Comprehensive blood test to assess cardiovascular risk by measuring Apolipoprotein B levels.
This test measures the level of Apolipoprotein B (apoB) in your blood. High apoB levels are linked to increased cardiovascular disease risk, as it reflects the number of LDL ('bad') cholesterol particles, not just their cholesterol content. Understanding apoB, alongside other lipid markers, provides a more complete cardiovascular risk assessment. Regular monitoring can aid early detection and management of cardiovascular risk. This test is often included in our popular Cholesterol Blood Test panel subscription.
Key Details
Who Is This For?
Adults over 20 as part of routine cardiovascular risk screening. Anyone with a family history of heart disease, high cholesterol, or stroke. People monitoring the effectiveness of statins or other lipid-lowering medications. Those with metabolic syndrome, diabetes, or obesity who face elevated cardiovascular risk.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
4The primary protein on LDL and VLDL particles. Each atherogenic lipoprotein particle carries exactly one ApoB molecule, making it a direct measure of the number of particles that can enter artery walls. Considered a superior predictor of cardiovascular risk compared to LDL cholesterol.
The combined measure of all cholesterol in your blood, including HDL, LDL, and VLDL. While useful as an overview, the breakdown between HDL and LDL is more clinically meaningful for assessing cardiovascular risk.
Often called 'good' cholesterol, HDL carries cholesterol away from arteries back to the liver for removal. Higher HDL levels are protective against heart disease. Exercise, healthy fats, and moderate alcohol intake can raise HDL.
The most common type of fat in the body, stored for energy. Elevated triglycerides — often from excess sugar, alcohol, or calories — increase cardiovascular risk and can cause pancreatitis at very high levels.
