Lipoprotein(a)

Understanding the marker

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle whose level is largely inherited. It adds information to cardiovascular risk assessment.

Lp(a) is assessed with other blood fats and health history. Its reported unit matters: mass units and particle-concentration units cannot be converted using one fixed factor. The need for repeat measurement depends on the clinical question.

What does high Lipoprotein(a) mean?

A high Lp(a) can add to cardiovascular risk. LDL, blood pressure, family history and other factors help determine its significance for an individual. Any prevention or treatment plan requires that wider assessment.

What does low Lipoprotein(a) mean?

Low Lp(a) means this particular risk factor is less prominent; it does not exclude other inherited or acquired cardiovascular risk.
