Apolipoprotein В, Apo B

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Apolipoprotein B (Apo B) is the main structural protein of atherogenic lipoproteins, including LDL cholesterol (“bad cholesterol”), VLDL, and other particles involved in transporting cholesterol to tissues.

Apo B levels reflect the total number of atherogenic lipoprotein particles in the blood and may provide a more accurate assessment of the risk of developing atherosclerosis and cardiovascular diseases compared with traditional lipid profile parameters.

An increased Apo B level indicates a higher number of particles capable of entering the arterial wall and contributing to the formation of atherosclerotic plaques. This test is useful both for cardiovascular risk assessment and for monitoring the effectiveness of cholesterol-lowering therapy.

Indications

Apo B testing is recommended:

• for global cardiovascular risk assessment and evaluation of atherosclerosis risk;
• in individuals with cardiovascular risk factors (high blood pressure, diabetes mellitus, obesity, smoking, family history of cardiovascular disease);
• for patients with a history of cardiovascular disease or atherosclerosis;
• when LDL-cholesterol levels may not fully reflect the actual cardiovascular risk;
• for patients with elevated triglycerides or lipid metabolism disorders;
• for monitoring the effectiveness of lipid-lowering therapy.

Test method

Measurement of apolipoprotein B concentration in blood is performed using the immunoturbidimetric method (or another validated immunochemical method depending on the laboratory platform used).

The method is based on the specific reaction between antibodies and apolipoprotein B molecules in the blood sample, allowing quantitative measurement of its level.

Procedure

The test is performed by collecting a venous blood sample.

The sample is analyzed in the laboratory to determine Apo B concentration. The result is interpreted by a physician together with other lipid profile parameters and individual cardiovascular risk factors.

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or a worsening of your condition, it is essential to consult a healthcare professional for proper diagnostic tests and treatment. Only a qualified specialist can make an accurate diagnosis and determine the appropriate treatment. To obtain the most accurate and consistent evaluation of your test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use different methods and units of measurement for similar tests.
