Protein fractions (Proteinogram)

Protein fractions (proteinogram) in biochemical blood analysis

Biochemical blood analysis is an important component of the diagnosis of various diseases and the state of the body in general. One of the important components of the analysis is the determination of protein fractions, which is sometimes called a proteinogram. Proteins in the blood perform many functions, and their concentration and ratio can be indicators of various states of the body.

A proteinogram is a separation of total blood protein into separate fractions based on their mobility in electrophoresis. The main protein fractions determined in a proteinogram include albumin, globulins, and fibrinogen. Let's take a closer look at these fractions and their role in biochemical blood analysis.

1. Albumin: This fraction accounts for about 60% of the total blood protein. Albumin is mainly synthesized in the liver and is responsible for maintaining the colloid osmotic pressure of the blood. It transports various substances such as hormones, drugs and minerals.
2. Globulins: Globulins are divided into alpha, beta and gamma globulins, each of which performs different functions. Alpha globulins mainly transport metal ions and some fatty acids. Beta globulins include fibrinogen, which plays a key role in blood clotting. Gamma globulins are antibodies, which are important for the immune system and fighting infections.
3. Fibrinogen: This fraction is also synthesized in the liver and is important for blood clotting. Fibrinogen is converted into fibrin, which forms clots in the blood that stop bleeding.

Why is it important to analyze protein fractions in the blood? Here are a few reasons:

1. Disease diagnostics: Changes in the concentration or ratio of protein fractions can indicate various diseases. For example, a decrease in albumin levels can be a sign of liver disease, and an increase in gamma globulins can indicate immune disorders.
2. Treatment monitoring: In the treatment of certain diseases, such as myeloma (a plasma cell tumor), a proteinogram can be used to determine the effectiveness of therapy.
3. Nutrition assessment: Albumin levels can indicate the state of nutrition and protein metabolism in the body.
4. Inflammation detection: Elevated globulins, particularly gamma globulins, may be a sign of inflammatory conditions.

Thanks to biochemical blood analysis and determination of protein fractions, we obtain valuable information about the state of the body and possible deviations from the norm. This helps doctors prescribe appropriate treatment and detect diseases in time, which increases the chances of successful treatment and recovery of the patient.
