Increased protein in the blood. Excess of total protein in the blood, causes of this condition, methods of diagnosis and treatment

Biochemical blood test gives important information about the work of certain organs and the whole organism as a whole. One of the leading roles in assessing the patient’s condition is played by a blood test for total protein, TBC. This concept means the presence in the blood of all protein molecules in total, including all kinds of fractions and subtypes. A deviation in this level may indicate unfavorable changes occurring in the body. We will tell you more about the indicator in this article.

Total protein in the blood, what is it?

Protein serves as the most important building material for almost all organs and tissues, as well as for creating cellular structures and plasma. It creates a kind of framework on which other cellular and molecular structures are attached. There is not a single cell or liquid substance in the human body that does not contain at least the slightest amount of protein.

There are a large variety of protein fractions: globulins, albumins, fibrinogens, etc., each of which has its own tasks and functions. For example, albumins maintain optimal cell structure, globulins are responsible for the activity of immune processes, fibrinogens are responsible for proper blood clotting. Norm total protein in the blood is determined by the method of the total concentration of all available components. Their insufficiency indicates the inferiority of the structures and functionality of organs and tissues.

Thus, protein plays the following significant roles in the body, namely:

Transports various substances, including nutrients, to organs and tissues;
Provides viscosity and ductility of blood;
It is the most important reserve storage of amino acids;
Regulates normal level Blood pH;
Retains elements of iron, calcium, copper and other useful substances in the blood;
Maintains the required volume of blood in capillaries and vessels.

Thus, establishing the level of OBC is one of the primary coefficients of complete protein metabolism, which is determined by the method of studying serum and blood plasma.

Normal level of total protein in blood

The OBC indicator is considered within normal limits if it is 65-85 g/l. However, such figures are very average and can change throughout life. Therefore, for each age category of patients, certain acceptable limits are established:

newborns - 48-75 g/l;
one-year-old children - 47-73 g/l;
children from 1-4 years old - 60-75 g/l;
children from 5 to 7 years old - 52-78 g/l;
children 8-15 years old - 58-76 g/l;
teenagers from 16 years old. and adults - 65-85g/l;
elderly people from 60 years old - 70-83 g/l.

The total protein norm in adult and healthy men should be in the range of 66-88 g/l. Whereas, the total protein norm in women’s blood may be slightly reduced, by about ten%, due to their physiological characteristics, since women have a greater need for protein, but a lower ability to produce it in the liver.

In addition, sometimes a situation is acceptable when the total protein level in the blood during pregnancy deviates downward by 30%, due to changes occurring in the woman’s body, due to increased needs and expenses associated with her current situation. The doctor concludes that total protein in the blood is reduced during pregnancy due to physiological reasons, only if the patient has no complaints and pathological symptoms.

Reasons when total protein in the blood is low

The condition when total protein in the blood is low is called hypoproteinemia in medicine. She may be; relative, absolute, and also physiological.

Hypoproteinemia is considered physiological if its development is not associated with any pathologies in the body. Typically, total protein is reduced during pregnancy, during breastfeeding, as well as in babies whose internal organs are not yet fully adapted to the formation of a full amount of protein molecules. A decrease in level can also be observed when the patient remains in the hospital for a long time. supine position, subject to bed rest. Or, on the contrary, frequent long-term physical exercise and overwork can provoke a decrease in the indicator.

Following strict diets or complete fasting can also lead to protein deficiency.

Relative hypoproteinemia is usually associated with an increase in fluid in the human circulatory system, and this happens for several reasons, for example:

an increase in the blood of the hypothalamus hormone, which is capable of retaining water in the body;
disturbance of normal urination (anuria);
intravenous administration of glucose in large doses;
drinking too much water (water poisoning).

Often, total protein is reduced in a patient as a result of the development of certain diseases, inflammatory processes. In this case, they talk about absolute hypoproteinemia, and it is usually associated with:

inflammatory diseases in the gastrointestinal tract associated with deterioration of protein absorption;
receiving extensive burns;
development of tumor formations;
exhaustion of the body as a result of a long-term serious illness;
disruption of the thyroid gland;
disorder of protein production in the liver, as a result of diseases such as cirrhosis or hepatitis;
HIV and other immunodeficiency states.

Only a doctor can determine the true reason for the decrease in BBC, based on the results of a complete examination. If necessary, the specialist will prescribe the “right” form of treatment, diet and medications to normalize protein levels.

Reasons why total protein in the blood is elevated

The situation when total protein in the blood is increased is called. hyperproteinemia. With such a condition in medical practice occurs much less frequently, and may be a sign of certain pathologies:

severe dehydration (with severe diarrhea/vomiting);
bleeding disorders;
severe intoxication;
allergic reactions;
intestinal obstruction, resulting in disruption of water balance.

Even after the analysis has shown that total protein is increased, it is not worth drawing unambiguous conclusions about the state of health. Only a comprehensive examination will allow the doctor to diagnose accurate diagnosis and appoint complex therapy.

The level of total protein in the blood of men and women should be regularly checked in order to promptly identify and prevent negative phenomena in the body.

The presence of protein in urine is determined using biochemical analysis urine. Normally, the protein should either be completely absent or present in trace amounts, and temporarily.

The filtration system of the kidneys physiologically filters out high molecular weight particles, while small structures can be absorbed into the blood from urine while still in the renal tubules.

Normal protein in urine

For men

The maximum norm for protein content in urine for representatives of the stronger sex is considered to be up to 0.3 grams per liter - this concentration can be explained by powerful physical shock loads on the body, stress, and hypothermia. Anything above this value is pathological.

For children

For most cases, no protein should be detected normally in children. The maximum value of this parameter should not exceed 0.025 grams per liter of urine. A deviation from the norm of up to 0.7-0.9 grams per liter of urine is sometimes observed for periods in boys aged from six to fourteen years - this is the so-called orthostatic or postural protein. It appears, as a rule, in daytime urine and is a feature of the kidneys during the period of teenage puberty of the stronger sex, most often due to increased physiological activity, against the background of a long stay of the body in an upright state. Moreover, the phenomenon is not periodic, i.e. in a repeated sample, the protein is often not identified.

For women

For pregnant women, up to thirty milligrams is considered normal, from thirty to three hundred milligrams is microalbuminuria. At the same time, a number of studies show that the concentration of up to three hundred milligrams of protein per liter of liquid in a classic daily biochemical analysis on later does not cause complications for the mother and fetus, so this indicator can be attributed to physiological proteinuria.

Causes of high protein

Increased protein in urine can be caused by a number of reasons.

Physiology

Powerful physical activity.
Excessive use food rich in protein.
Long stay V vertical position with corresponding disruption of blood flow.
Late pregnancy.
Long stay in the sun.
Hypothermia of the body.
Active palpation of the kidney area.
Severe stress, concussions, epileptic seizures.

Pathology

Congestion in the kidneys.
Hypertension.
Nephropathies of various etiologies.
Amyloidosis of the kidneys.
Pyelonephritis, genetic tubulopathies.
Tubular necrosis.
Rejection of transplanted kidneys.
Multiple myeloma.
Hemolysis.
Leukemia.
Myopathies.
Feverish conditions.
Tuberculosis and kidney tumors.
Urolithiasis, cystitis, prostatitis, urethritis, bladder tumors.

What does increased protein in urine mean?

In adults and children

Excess normal indicators in adults and children, it usually means the presence in the body of physiological or pathological problems that require identification, correct diagnosis and appropriate treatment.

Exceptions, as mentioned above, are made for representatives of the stronger sex in adolescence, if the increase in protein concentration is of an irregular, non-systemic nature.

Mild degrees of proteinuria (up to one gram of protein per liter of urine) are usually eliminated quite quickly, moderate (up to 3 g/l) and severe (over 3 g/l) require not only the highest quality diagnosis, but also a fairly long complex treatment, since they are usually caused by serious pathologies.

In pregnant women

Modern research shows that physiological changes in the body in pregnant women, especially in the later stages, with a protein concentration of up to 0.5 grams per liter of urine do not affect negative influence for the fetus and the woman, however, if the above parameters exceed the specified limit of 500 milligrams/liter of urine, then the fair sex interesting position will be needed comprehensive diagnostics and treatment, naturally taking it into account physiological state, as well as a competent assessment of the risks for the unborn child.

Treatment

Specific treatment of proteinuria, regardless of the gender and age of the patient, is aimed at eliminating the causes pathological condition, as well as neutralizing negative symptomatic manifestations.

Because to be called increased protein in urine can be caused by a number of factors, then specific therapy is prescribed by a qualified physician only after a thorough diagnosis of the patient and an accurate determination of the disease or physiological condition.

With moderate and severe manifestations of proteinuria with manifestation nephrotic syndromes of different etiologies, a person requires hospitalization, bed rest, a special diet with maximum restrictions on salt and liquids. The groups of drugs used (depending on the cause of the condition) are immunosuppressants, corticosteroids, cytostatics, anti-inflammatory/antirheumatic, antihypertensive drugs, ACE inhibitors, as well as blood purification by hemosorption or plasmaformesis.

If a person has a weak form of proteinuria caused by an orthostatic or functional factor, then medications, as a rule, are not used: normalization of circadian rhythms is relevant, correct selection diet, as well as giving up a number of bad habits.

Blood test for total protein is undeniably important, since protein is responsible for many functions in the human body, namely:

responsible for the ability of blood to coagulate and for its fluidity;
sets the volume of blood in the vessels;
responsible for the transmission of vital important substances By blood vessels(these substances include fats, hormones, and other compounds);
responsible for the stability of blood pH; supports protective functions body.

Total blood protein includes albumin and globulins. Albumin is mainly produced in the liver, and globulins are synthesized by lymphocytes.

Blood protein must be determined in cases where the following diseases are suspected:

any violations related to reduced immunity (infectious diseases, various systemic disorders)
collagenosis
disorders of the kidneys and liver
neoplasms
thermal burns
anorexia, bulimia

In order to determine the amount of protein in the blood, it is necessary to take the test strictly on an empty stomach. morning time. The norm is a protein level of 66-88 g/l for adults and children over 14 years of age. For children under 1 year old, the protein norm is 44-73 g/l, for children 1-2 years old - 56-75 g/l, for children 2-14 years old this figure ranges from 60 to 80 g/l.

Protein deficiency in the blood can be observed when physiological changes in the body, that is, during pregnancy and breastfeeding, during long-term immobilization, as well as in children under 7 years of age. Reduced level protein in the blood is called hypoproteinemia . A relative decrease in blood protein levels usually occurs when the volume of blood in the system increases.

An absolute lack of protein in the blood can be a sign of the following diseases:

limited intake of proteins from food. This occurs during fasting, diets, refusal of protein foods, various functional disorders digestive system(pancreatitis and others), with prolonged inflammatory diseases intestines and other diseases accompanied by decreased digestibility of proteins;
various liver diseases that lead to disruption of protein synthesis;
extensive burns, constant bleeding, chronic disorders kidneys also lead to a decrease in protein levels in the blood, since in these conditions the body intensively loses protein;
protein breaks down when the body overheats for a long time, thermal burns, cancer, intense training and other stress, as well as hyperfunction thyroid gland(thyrotoxicosis);
in the case when the protein goes beyond the bed of the vessel;
water poisoning (excess water in the body).

Increased protein is rare and is a sign of the following pathologies:

autoimmune diseases, such as autoimmune thyroiditis;
acute infections;
chronic infections;
lack of water in the body;
malignant tumors with excessive production of harmful proteins.

An elevated level of protein in the blood is medically called hyperproteinemia .

When deciphering a blood test, it is necessary to take into account that excess or insufficient protein can be caused by taking certain medications, such as corticosteroids and estrogen-containing drugs ( oral contraceptives and others). It is also important to consider what time of day the analysis was taken. It is not for nothing that blood sampling is recommended to be done in the morning, since at night the level of protein in the blood changes slightly. Another factor to remember is what position the patient was in when the blood was drawn. The protein level always increases if the patient is lying down and suddenly stands up. If the tourniquet is applied too tightly to the arm when drawing blood, it can compress the blood vessels and cause an increase in protein levels.

Only a doctor can correctly decipher the result of a blood test, so if the protein is increased or decreased, the patient must contact his or her primary care physician. family doctor. Even if the deviation from the norm is insignificant, you should immediately consult with a specialist in order to prevent the condition from worsening and to identify pathology in time, if any. Protein levels outside the normal range are detectable medicinal correction, after which it is necessary to take a blood test again to determine the effectiveness of the therapy.

The content of total protein in the blood is determined by biochemical analysis. Such an examination is prescribed when various diseases or suspicion of them. Therefore, it is quite understandable that many are interested in: why is the total protein in the blood elevated, what does this mean? Protein is a necessary component of many processes. Changes in its content indicators are a reflection of various disorders and pathologies.

Briefly about the main thing

“Total protein” is a summary term that combines substances of protein nature that are contained in whey. They are needed for:

participation in coagulation processes;
maintaining oncotic plasma pressure;
maintaining blood pH within normal limits;
transport of substances throughout organs;
immune processes;
formation of “protein reserve”;
regulation of various physiological processes that occur in the body.

Protein formation occurs in immune system and liver. Any pathology associated with their functioning leads to disruption of protein metabolism.

Indicators are normal

in a newborn, the protein content in the blood is 45-70 g/l;
for a child up to 12 months - 50-75 g/l;
in a child over three years old - 60-81 g/l;
adult - 66-87 g/l;
elderly people blood protein - 62-82 g/l.

Modern diagnostic methods make it possible to accurately determine abnormalities in blood tests. Children must be tested once a year.

Causes of increased blood proteins

An increase in plasma protein is associated with impaired functioning of the body and its systems. It comes in three types. When absolute, the increase does not provoke an increase in blood volume. The relative type is characterized by thickening of the blood. The third option, when plasma protein is elevated, includes physiological abnormalities.

The reasons leading to the development of all options are different. Among those that can increase the amount of proteins in the first case are:

cancer diseases;
acute severe infection;
autoimmune diseases;
the presence of chronic inflammation.

The reasons that provoke the development of the relative form include:

acute intestinal infections;
intestinal obstruction;
poisoning;
sudden heavy bleeding;
long-term use of corticosteroids;
excess permissible quantity medications.

High protein with natural deviations from optimal indicators occurs when long-term use protein foods or bed rest. In addition, carrying a child, breastfeeding, and excessive physical activity are provoking factors. A false increased concentration of proteins is possible when the tourniquet is kept in the forearm for a long time during blood sampling; sudden change in bodily position.

Increased protein content can be detected when consuming: androgens, corticosteroids, insulin, progesterone, thyroid hormone preparations. Detection of excess levels of total protein in the body to confirm the diagnosis of the presence of a particular disease requires other examinations. In addition, the patient's medical history must be carefully collected. This is due to the fact that increased protein in the blood indicates the presence of pathology, but does not focus attention on the area of the disorder.

Reduced protein content

Reduced protein in the serum may indicate the presence of some disease, or some physiological shifts. In the first option, the causes are: hepatitis, constant bleeding, kidney pathologies, varied diets, fever, intoxication. The protein content can be reduced by: pregnancy, breast-feeding, exercise stress.

Proper preparation for the examination

In order for the indicators of biochemical analysis to be identified as accurately as possible, it is necessary to follow some rules. These include:

visiting the laboratory to donate blood in the morning, on an empty stomach;
the last meal should be approximately eight hours before the test;
the day before it is necessary to refuse large quantity protein foods, doctors mean meat, eggs, nuts;
avoid excessive physical activity, from which the indicator increases;
Do not drink a lot of fluids the day before.

The presence of such requirements is due to the characteristics of the measured indicators. Due to certain factors, they may change. In order for this analysis to show correct results, they should not be neglected.

What to do

Due to the fact that total protein may increase with serious illnesses, changes in blood counts during the examination should alert you. Health monitoring is required.

To do this, you need to visit a doctor.

After carrying out the necessary additional examinations, the specialist will find out why the increased protein in the blood occurred. In order to reduce its content, it is necessary to eliminate the root cause, that is, the underlying disease. And this is impossible without the intervention of a doctor. Folk remedies it is impossible to reduce the amount of total protein. The doctor will take into account all the factors that increase the indicators, make a diagnosis and prescribe medications.

Protein is the component without which harmonious functioning is impossible human body. Therefore, it is quite natural that when conducting research, one is interested in the question: why is the total protein in the blood elevated and what does this mean? Sometimes there is a clear excess of protein in the blood, which is clearly reflected in the analysis data. In some situations, indicators are on the border of normal, when not only increased, but also decreased protein is noted. In any case, the condition that has arisen means the need for medical supervision.

In contact with

If a person, when decrypting general analysis blood test (CBC), if elevated protein is detected in the blood, it is necessary to pay attention to this, because this condition often accompanies ongoing inflammatory phenomena in the body.

Because the high concentration proteins may be a symptom various pathologies, people are often lost, not understanding the reasons for this condition.

Therefore, the relevant questions are what functions do proteins perform in the blood, what is the normal level of their concentration, why is there an increased protein content in the blood, and what does this mean?

There are a lot of protein compounds in the human body. Having modern blood analyzers available, doctors identify about 30 protein compounds that are of interest for making a diagnosis and determining a particular pathology.

Most often isolated following products biochemical protein synthesis:

Albumin is the main protein component of blood plasma. It is a water-soluble protein consisting of about sixty amino acids;
globulins. The globulin family consists of globular proteins, the main function of which is considered to be the ability to clot blood. They do not dissolve in water as well as albumins, but they easily interact with salt compounds;
C-reactive protein. This protein is very important for diagnosing diseases, because an increase in reactive protein in the blood occurs, as a rule, in response to damage to any internal organ or tissue, penetration of an infection of any etiology into the body, or helminthic infestation;
hemoglobin. Gives blood its inherent red color, is part of red blood cells, and participates in oxygen metabolism.

If doctors say that the total protein in the blood is increased, they usually mean that the content of albumin and globulin is above the norm.

The work that proteins do in human blood is enormous.

Below are some of their functions:

necessary maintenance of blood clotting ability;
regulation of colloid osmotic pressure of blood plasma. Its decrease leads to urinary retention and edema;
provide the necessary acid-base balance body;
carry out transport functions for the delivery of oxygen, fats, minerals, vitamins and hormones to internal organs;
immunoglobulins protect the body from the penetration of foreign harmful microorganisms;
created in the liver necessary for a person a supply of amino acids, which in case of insufficient consumption of protein products will be used by the brain, heart and other internal organs;
participate in the activity of the enzymatic system.

Proteins are produced mainly by the liver, so any disturbance in its functionality immediately affects the amount of proteins in the blood.

Their total concentration directly depends on the rate at which protein metabolism occurs and how quickly albumins and globulins are generated and utilized.

Root causes of increased protein

Depending on age, the protein content in the blood of people varies. Thus, a newborn child may have a minimal amount of protein fractions in the blood - from 43 to 69 g/l.

in children under one year of age – from 49 to 72 g/l;
in children from one to four years of age - from 50 to 75 g/l;
from 5 to 7 years – 52-79 g/l;
from 8 to 15 years – 58-80 g/l;
in adults – 65-81 g/l;
in elderly people over 65 years old – 65-85 g/l.

Based on the equipment used by a particular laboratory, the units of measurement of proteins in the blood may vary, as well as the average normal values.

Therefore, when diagnosing any disease, doctors are guided by significant deviations from the upper and lower limits of protein concentration.

Violation normal amount proteins may depend on physical condition healthy person.

Thus, a condition where reactive protein in the blood is elevated can be observed when athletes engage in intensive cardio training and consume large amounts of protein foods.

In addition, in people with disorders cerebral circulation can be fixed high level proteins in the case when they suddenly rise from the bed.

However, these types of physiological factors influence the total protein concentration slightly, changing it upward by a maximum of 10%.

Most often, the situation when a person’s blood has a stable increase in protein indicates some kind of pathological processes taking place in his body.

Therefore, doctors, when issuing a referral for biochemical research the amount of protein in the blood is guided by the following indications:

a person has extensive damage skin as a result of injuries or burns;
possible pathological abnormalities in the activity of the liver and kidneys;
damage to the body by various infectious invasions;
pregnancy status;
suspicion of malignant neoplasms;
state of anorexia.

Absolute hyperproteinemia occurs when protein concentration increases without a decrease in blood volume.

The reasons for its occurrence may be the following:

the formation of large septic foci in the body as a result of an infectious lesion;
the chronic nature of inflammatory processes, which is characterized by constant destruction of certain tissues;
cancer tumors that have their own increased protein metabolism;
autoimmune processes in which the immune system “takes arms” against healthy cells the body, considering them foreign and harmful, and produces autoantibodies and C-reactive protein.

Relative hyperproteinemia is associated with a decrease in total blood volume.

This condition can be caused by the following factors:

dysentery, cholera and other severe infectious diseases accompanied by significant dehydration due to uncontrollable vomiting and diarrhea;
state intestinal obstruction, in which water stops being absorbed into the intestinal walls;
excessive blood loss leading to a decrease in blood volume in the human body.

Long-term treatment hormonal drugs and insulin, as well as vitamin A deficiency can also lead to blood thickening and relative hyperproteinemia.

A course of treatment

Both absolute and relative hyperproteinemia are conditions that are corrected by treating the disease that caused them.

Therefore in case high content proteins in the blood, doctors, first of all, pay attention to general state patient, his medical history, complaints about health and prescribe additional examinations to make an accurate diagnosis and eliminate the cause of high protein concentrations.

If the total protein in the blood is increased, then we can talk about a variety of diseases accompanying this phenomenon.

It’s another matter when a high concentration of C-reactive protein (CRP) is detected in the blood. It is considered an indicator of inflammatory phenomena occurring in the human body because it is more sensitive to them than the erythrocyte sedimentation rate (ESR).

Reasons for high content C-reactive protein in the blood most often serve:

various allergies, characterized by concomitant inflammatory phenomena;
septic lesions, meningitis, tuberculosis and other severe infections in the acute stage;
type II diabetes mellitus and other disorders of the endocrine system;
myocardial infarction as a result of necrosis of cardiac tissue, extensive abdominal surgery.

If none of these factors of high CRP have been identified, and its content in the blood is high, then additional examinations are necessary.

Perhaps the doctor will order an MRI of the brain, ultrasonography internal organs, because in this case there is a high probability malignant neoplasms, which cause this kind of deviation from normal values SRP concentrations.
