Doctor's Assessment Included

Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.

Cardiovascular

ApoB (Apolipoprotein B)

ApoB counts the atherogenic particles that drive heart disease. Knowing your number helps you take targeted action to protect cardiovascular health.

Reference Ranges

Male
g/l
Normal < 1.3 High

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the total number of atherogenic lipoprotein particles by quantifying ApoB protein. It is considered by many experts to be a superior marker of cardiovascular risk compared to LDL cholesterol.

Why It Matters

ApoB may be a stronger predictor of cardiovascular events than LDL cholesterol because it counts all atherogenic particles, not just cholesterol content. Elevated ApoB may increase risk even when LDL appears normal. Consult your healthcare provider.

When to Test

Testing is recommended for comprehensive cardiovascular risk assessment, particularly if you have metabolic syndrome, diabetes, or a family history of premature heart disease.

Symptoms

Low Levels

Low ApoB levels are generally favourable and suggest fewer atherogenic particles in circulation.

High Levels

Elevated ApoB does not cause direct symptoms but is associated with accelerated atherosclerosis and increased cardiovascular event risk over time.

Lifestyle Tips

A heart-healthy diet low in saturated fat and trans fat, regular exercise, maintaining a healthy weight, and managing metabolic conditions can all help lower ApoB levels.

Frequently Asked Questions

Is ApoB better than LDL for predicting heart disease?
Many experts consider ApoB a more accurate predictor because it measures the number of atherogenic particles rather than just the cholesterol they carry. Discuss with your healthcare provider which markers are most relevant for you.
Can ApoB be high with normal LDL?
Yes, this can happen when you have many small, dense LDL particles. Each carries less cholesterol but the same one ApoB, so particle count (ApoB) may be elevated even when LDL cholesterol appears normal.
How can I lower my ApoB?
Diet, exercise, weight management, and when necessary, medical treatment can help lower ApoB. Your healthcare provider can develop an appropriate plan for you.
