APO B | Apolipoprotein B

The test is performed only with the determination of apolipoprotein A1. The concentration of apolipoprotein B in the blood is determined to calculate the Apo A1/Apo B ratio. The higher this ratio, the lower the risk of atherosclerosis. Apolipoprotein B is associated with LDL cholesterol ("bad" cholesterol), so its lower values are a favorable prognostic factor in atherosclerosis, coronary heart disease.

Determination of apolipoproteins is important when: 1) elevated or moderately elevated lipid values are determined for the patient (by examining cholesterol, LDL cholesterol, triglycerides); 2) persons suspected of lipid metabolism disorders (for example, 10% of all myocardial infarction patients are diagnosed with familial combined hyperlipidemia).

Lipid values when Apo should be tested:

Cholesterol - 5.2-7.8mmol/l;
Triglycerides – 2.3–4.6 mmol/l;
LDL cholesterol - 3.5-4.5 mmol/l.
