Lipoprotein (a)
A Lipoprotein (a) Test measures the level of lipoprotein (a) in the blood and helps assess the risk of heart disease and stroke.About Test
The Lipoprotein (a) Test measures the level of lipoprotein (a), also known as Lp(a), in the blood. Lipoprotein (a) is a type of low-density lipoprotein (LDL) that carries cholesterol in the bloodstream.
High levels of lipoprotein (a) are associated with an increased risk of cardiovascular diseases such as heart attack, stroke, and narrowing of blood vessels. Elevated Lp(a) levels may contribute to the buildup of fatty deposits (plaque) in the arteries, which can restrict blood flow.
Unlike many other cholesterol markers, lipoprotein (a) levels are largely determined by genetics and may remain high even when lifestyle changes or medications control other cholesterol levels.
The Lipoprotein (a) test helps doctors better evaluate a person's overall heart disease risk, especially in individuals with a family history of early heart disease or unexplained cardiovascular problems.
