Apolipoprotein A1, Serum

Diagnostic Use

Apolipoprotein A (ApoA) is the principal protein associated with high-density lipoprotein (HDL) particles, which plays a role in reverse cholesterol transport.

HDL cholesterol (HDL-C) and ApoA concentrations are inversely related to the risk for coronary artery disease (CAD). There are a variable number of ApoA proteins per HDL particle, thus ApoA is not strictly a surrogate marker for HDL-C.

It is not to be confused with lipoprotein (a), which has a fundamentally different role and interpretation.
