Apolipoprotein A1 and B
This test looks at two proteins that carry cholesterol through your bloodstream: Apolipoprotein A1 (found in HDL, "good" cholesterol) and Apolipoprotein B (found in LDL, "bad" cholesterol). Some research suggests these markers predict heart disease risk more precisely than a standard cholesterol test, particularly for people with diabetes or metabolic syndrome.

Overview
About This Test
Apolipoprotein A1 and B are proteins that transport cholesterol through your bloodstream. ApoA1 is the main protein in HDL ("good") cholesterol, while ApoB is found in LDL ("bad") cholesterol and other artery-clogging particles. Because ApoB reflects the actual number of these particles rather than just how much cholesterol they carry, some research suggests it can be a more precise indicator of cardiovascular risk than a standard cholesterol panel alone, especially for people with diabetes or metabolic syndrome. This test is often ordered as a follow-up when standard cholesterol results don't fully match a person's overall risk profile, or when there's a strong family history of heart disease.
