Diagnostic Blood Test:

Apolipoprotein A-1 (ApoA1)
Apolipoprotein B (ApoB)
ApoA1:ApoB Ratio

Apolipoprotein A-1 (ApoA1) is a protein that is part of high-density lipoprotein (HDL), also known as “good” cholesterol. It helps remove extra cholesterol from tissues and carries it to the liver to be recycled or removed from the body. Low levels of ApoA1 may signal a higher risk of developing heart disease.

Apolipoprotein B (ApoB) is a protein found in different types of “bad” cholesterol, including low-density lipoprotein (LDL), lipoprotein(a), and very low-density lipoprotein (VLDL). ApoB can transfer extra cholesterol into the body’s tissues. High levels of ApoB in the blood are linked to a higher risk of developing heart disease.
