A high lipoprotein(a), or Lp(a), result can signal inherited cardiovascular risk even when standard cholesterol numbers look normal. A low result is usually reassuring, but it does not cancel out other heart-risk factors.
A lipoprotein(a) blood test measures an inherited cholesterol-related risk factor that is not included in a standard lipid panel. Learn who should consider testing, how to prepare, what results mean, and how to compare direct-to-consumer lab options.
High ApoB usually means more artery-plaque-forming lipoprotein particles; low ApoB often means fewer particles, but very low results may need follow-up if unexpected.
An apolipoprotein B blood test measures ApoB, a marker of the number of cholesterol-carrying particles that can contribute to artery plaque. Learn when it is useful, how to prepare, and how to interpret results with your clinician.
A lipid panel blood test measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides to help estimate cardiovascular risk and guide prevention conversations.
