Apolipoprotein B (ApoB) is the primary protein component of low-density lipoprotein (LDL). Apolipoprotein A1 (ApoA1) is the primary protein associated with high-density lipoprotein (HDL).
This test is to assess the risk in patients at target non-HDL-C (or LDL-C) and also to follow-up studies in individuals with non-HDL-C (or LDL-C) values inconsistent with risk factors or clinical presentation.
The normal range for apoB is 40-125 mg/dL. Usually less than 100 mg/dL is considered desirable in low or intermediate risk individuals. Less than 80 mg/dL is desirable in high risk individuals, such as those with cardiovascular disease or diabetes.
