Albumin in biochemical analysis of blood

Biochemical blood tests today are used very often as an auxiliary method in diagnosing. Moreover, the definition of certain indicators is important for specialists of all areas and profiles. One of the commonly encountered indicators is albumin or protein fractions in a biochemical blood test. So if the doctor has appointed to pass the analysis for protein or protein fractions, then you will be interested and helpful in our article. Let's take a closer look at what albumin is and why do you research this component?

Albumin in the blood, what is it?

Albumin is the main, key protein in human blood plasma, and makes up approximately 50-65% of the total amount of plasma. This component is synthesized in the liver, and the period of albumin life is approximately 15-20 days.1 albumin molecule includes a great variety of amino acids, up to six hundred varieties. But still these protein fractions of blood belong to a low molecular weight, simple protein group. The main composition of proteins is located in the peripheral blood, but there is also a “spare” part, which is located in the lymph, in the fluids of the spinal cord and in the extracellular space.

Proteins are extremely important for the full activity of the human body. Albumin is not an exception, circulating in the blood, it performs a number of vital purposes:

  • binds and transports various substances in the body( for example, hormones, acids, bilirubin, calcium, cholesterol, etc.), i.e.performs a transport function in the body - this is one of the main tasks of this protein fraction;
  • maintains pressure in the blood plasma, thanks to this, in a person whose blood is within the normal range of albumin in the blood, there are no fluids and no blood flow and no swelling;
  • still can not fail to note the backup function of albumin, because protein molecules contain huge amounts of amino acids, which are essential for the proper functioning of the body, with prolonged fasting, they are primarily consumed.

Protein fractions of blood are separate subgroups of proteins, the change in the ratio of which may give the doctor more important information when diagnosing than the result of the analysis for “total protein”.

The level of albumin is the most important value by which overall human health is assessed. In addition, the deviations of the indicator can signal the presence of rheumatic and oncological diseases, liver or kidney pathologies.

Blood normTherefore, speaking of the normal values ​​of albumin, the doctor relies only on the age scheme of division.

So, for children of early age, the indicator from 25 to 50 g / l is considered normal;

For older children up to 14 years old, an indicator from 38 to 54 g / l will be acceptable;

For a more adult population from 14 to 60 years old, albumin has a blood norm of 33-55 g / l;

And in older people older than 60, a slight decrease in the level to 34-48 g / l is permissible.

In a biochemical study, the analysis may show a reduced protein in the blood during pregnancy, as well as during lactation, and is most often equal to 30-34 g / l. After giving birth or ending breastfeeding, the rate should return to normal.

If it is revealed that albumin in the blood is increased or decreased, then this may be due to both external and hidden internal changes that often signal the development of an “unhealthy” process in the body.

Albumin is elevated

A doctor states hyperalbuminemia if the result of the study showed that this protein in the blood is above normal. This is most often evidence of dehydration. This happens, for example, with prolonged diarrhea, vomiting, and severe fluid loss. In the state of dehydration, the blood of a person is strongly thickened, which can negatively affect the general state of health.

A situation where albumin is elevated in the blood is quite rare. However, nevertheless, hyperalbuminonemia may accompany some pathological processes occurring in the body. If blood protein is elevated, the causes may be associated with the development of the following diseases:

  • cholera;
  • intestinal obstruction;
  • lupus erythematosus;
  • diabetes;
  • hepatitis or cirrhosis;
  • diabetes;
  • received multiple burns;
  • taking certain medications( such as corticosteroids or bromsulfalein).

There are some non-drug ways to lower protein in the blood. First of all, you need to revise your usual way of life. It is recommended:

  • to follow a diet, eating foods low in protein and carbohydrates, avoid fried, salty and sweet;
  • not to consume alcoholic beverages, since the kidney, which struck alcohol, can not fully synthesize and absorb proteins;
  • does not smoke, as in chronic smokers there is an increased risk of developing hypertension, and more often blood pressure rises, but it is better to gradually give up the bad habit;
  • to drink more fluids is the main recommendation with an increased level of albumin, since dehydration is the most common cause of overestimation.

For more severe situations, medical intervention is likely to be necessary. In this case, only the doctor will be able to select the desired drug from the group of inhibitors or statins.

Causes of

reduction Hypoalbuminemia is a condition in which the level of the protein fraction under consideration is lowered and is less than 25-30 g / l. Reduced protein in the blood is the reason for the doctor to suspect that a person has certain pathological conditions, such as:

  • tumor formation;
  • nephrite;
  • leukemia, blood poisoning;
  • heart failure;
  • hepatic insufficiency;
  • rheumatic diseases;
  • severe injuries and burns;
  • suffered prolonged and heavy bleeding;
  • . Other hereditary diseases, leading to a decrease in body proteins.

If we are not talking about pathological, but about physiological reasons, then it is often found that blood protein is lowered during pregnancy, because a woman “shares” with him all the necessary components, including protein, during the child's pregnancy. You can fill the gap with the help of a well-chosen balanced diet.

It is important to note that a decrease in albumin sometimes occurs while taking certain medications, especially if there is an overdose.

Also, there is often a decline in cigarette lovers. The same applies to people who abuse alcohol.

With regard to ways to increase albumin in the blood, first of all, experts advise to pay attention to the products that are consumed daily, and to give preference to the fact that the composition has a high protein content. These include eggs, dairy / dairy drinks, meat / chicken, oatmeal, fish and seafood.

Bad indicators are often associated with deterioration of the liver, and therefore the second task is the elimination of all negative factors for it. To a large extent, this is excessive salt intake, alcohol abuse, the presence of acute infectious / viral diseases, the presence of obesity, long-term drug treatment.

Another effective way to increase protein in the blood is to use a special herbal drink, which can be found in the pharmacy as a liver tea or collection. It will help to normalize the proper functioning of the liver, clean it from harmful and toxic substances, and improve the general well-being of a person. This drink has no practical contraindications and side effects, but still before use, it is better to coordinate the reception with your doctor.
