Order Apolipoprotein B Test, (Apo-B)Apolipoprotein B (Apo-B) testing measures the concentration of apolipoprotein B in the blood. Apo-B is the primary protein component of several atherogenic lipoproteins, including low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), and lipoprotein(a). Because each of these particles contains exactly one molecule of Apo-B, the test provides a direct count of the number of circulating atherogenic particles rather than an estimate based on cholesterol content.
About Apolipoprotein B Test, (Apo-B) in San Buenaventura
Apolipoprotein B Testing, (Apo-B) is a blood test that quantifies the concentration of apolipoprotein B, a structural protein found on the surface of atherogenic lipoproteins.
Apolipoprotein B serves as the principal protein constituent of LDL, VLDL, IDL, and lipoprotein(a). Each of these particles carries a single Apo-B molecule, so the measured concentration reflects the total number of these particles in circulation. This distinguishes Apo-B from standard lipid panel measurements, which assess the cholesterol carried within lipoproteins rather than the particle count itself.
The test is typically ordered to evaluate cardiovascular risk, particularly when a standard lipid panel may not fully capture the burden of atherogenic particles. Some individuals may have normal LDL cholesterol levels but an elevated Apo-B concentration, a pattern that can indicate an increased number of small, dense LDL particles. Apo-B testing may also be used to monitor the effectiveness of lipid-lowering therapies.
Sample collection involves a standard venipuncture, with blood drawn into a collection tube and sent to a laboratory for analysis. Turnaround time is usually one to three business days. Preparation instructions should be followed as provided by the laboratory performing the test.
