Lipoprotein(a), or Lp(a), is a type of lipoprotein particle that is largely determined by genetics. It is structurally similar to LDL but with an additional protein called apolipoprotein(a).
Category: lipids
Also known as: lipoprotein a, lp(a), lpa, lp a, lipoprotein(a)
Reference range: 0–75 nmol/L (Source: ABIM)
Standard unit: nmol/L
High values may indicate
High Lp(a) levels may indicate increased risk of heart disease, stroke, aortic valve stenosis, and atherosclerosis, largely driven by genetic factors.
Low values may indicate
Low Lp(a) levels are generally favorable and associated with lower cardiovascular risk. There are no known clinical concerns with low Lp(a).
