Apolipoprotein A2 (ApoA2)

What is Apolipoprotein A2 (Apo A2)?

Apolipoprotein A2 is a protein component of High-Density Lipoprotein (HDL), also known as the "good" cholesterol. Apo A2 plays a role in fat metabolism and can influence the enzymatic activity involved in the conversion of dietary fats. Although it is less prominent than Apo A1, Apo A2 contributes to the stability and functionality of HDL particles in the blood.

Why should you test Apolipoprotein A2 (Apo A2)?

Testing for Apo A2 can provide insight into the composition and functionality of HDL cholesterol, which can help in evaluating the risk of cardiovascular disease. It may be particularly important for individuals with a known history of heart disease or for whom standard cholesterol tests provide insufficient information about their risk profile.

What does it indicate?

Apo A2 levels can help in assessing the quality of HDL cholesterol and the effectiveness of the body's cholesterol transport mechanism. This can offer additional insights beyond traditional cholesterol measurements.

What does a high level of Apolipoprotein A2 mean?

A high level of Apo A2 may indicate a healthy composition of HDL cholesterol, which can potentially lower the risk of cardiovascular disease. However, the interpretation of Apo A2 levels must always be considered in combination with other lipid values and risk factors.

What does a low level of Apolipoprotein A2 mean?

A low level of Apo A2 may indicate a less favorable composition of HDL cholesterol or disturbances in fat metabolism, which may increase the risk of cardiovascular disease.
