Diagnostic Blood Test:
Lipoprotein(a) is a form of low-density lipoprotein (LDL) or “bad” cholesterol. This protein is smaller and denser than other types of LDL, allowing it to lodge into blood vessel walls more easily. High lipoprotein(a) levels can indicate an elevated risk of developing a heart attack, stroke, or heart disease. Levels of Lp(a) are largely genetically determined.
