Additional Information: Lp(a) measurements can help determine risk for cardiovascular disease (CVD), and does so independently of other lipids. The level of Lp(a) is genetically determined and is not easily modified by lifestyle changes or drugs. However, some non-genetic conditions may lead to elevated Lp(a). These include estrogen depletion, familial hypercholesterolemia, severe hypothyroidism, uncontrolled diabetes, chronic renal failure, and nephrotic syndrome. There are no known problems associated with low Lp(a). Many individuals have no detectable Lp(a) in their blood.
