What does the Lipoprotein(a) (Lp(a)) - Lp(a) blood test mean? Get a free analysis of your blood test now. Here's what you get with our free analysis:
Lipoprotein(a), or Lp(a), is a type of lipoprotein that carries cholesterol in the blood. It's similar to LDL cholesterol but has an additional protein called apolipoprotein(a) attached to it. Lp(a) levels are largely determined by genetics and remain relatively stable throughout life. High levels of Lp(a) are associated with an increased risk of cardiovascular disease, including heart attacks and strokes. This test is used to assess cardiovascular risk, especially in individuals with a family history of early heart disease or those with unexplained atherosclerosis. Unlike other lipid markers, Lp(a) levels are not significantly affected by diet or lifestyle changes, making it a unique risk factor for heart disease.
A low Lp(a) reading, below the range lower limit, is generally not a cause for concern. In fact, lower Lp(a) levels are associated with a reduced risk of cardiovascular disease. Individuals with low Lp(a) levels may have a genetic predisposition to produce less of this lipoprotein. However, it’s important to note that a low Lp(a) level does not guarantee protection against heart disease, as other risk factors may still be present. Always consider Lp(a) results in conjunction with other lipid markers and overall cardiovascular risk assessment.
A high Lp(a) reading, above the range upper limit, indicates an increased risk of cardiovascular disease. Elevated Lp(a) levels are associated with a higher likelihood of developing atherosclerosis, heart attacks, and strokes. This risk is independent of other lipid markers and traditional risk factors. High Lp(a) levels are largely genetic and not significantly influenced by diet or lifestyle changes. Individuals with high Lp(a) may require more aggressive management of other cardiovascular risk factors and closer monitoring. In some cases, specific treatments targeting Lp(a) may be considered, although options are currently limited.
