Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
ApoA1 (Apolipoprotein A1)
ApoA1 reflects your HDL's protective capacity against heart disease. Cardiovascular risk increases after menopause, making this marker especially relevant for women.
What It Measures
This test measures the level of ApoA1 protein in your blood. It provides a direct measure of the functional component of HDL cholesterol.
Why It Matters
Higher ApoA1 levels are generally associated with lower cardiovascular risk. ApoA1 may provide a more accurate cardiovascular risk assessment than HDL cholesterol alone. Consult your healthcare provider.
When to Test
Testing may be recommended as part of advanced cardiovascular risk assessment, especially when standard lipid panels are inconclusive or when there is a family history of heart disease.
Symptoms
Low Levels
Low ApoA1 may be associated with increased cardiovascular risk. There are typically no direct symptoms, but it suggests reduced cholesterol clearance from arteries.
High Levels
High ApoA1 levels are generally considered protective and are not associated with adverse symptoms.
Lifestyle Tips
Regular aerobic exercise, moderate alcohol consumption, omega-3 fatty acids, and a diet rich in healthy fats can support healthy ApoA1 levels. Avoiding smoking and maintaining a healthy weight also help.
Frequently Asked Questions
How is ApoA1 different from HDL cholesterol?
HDL cholesterol measures the cholesterol carried by HDL particles, while ApoA1 measures the protein that makes HDL functional. ApoA1 may better reflect cardiovascular protection.
What is the ApoB/ApoA1 ratio?
This ratio compares atherogenic to protective lipoproteins and may be a powerful predictor of cardiovascular risk. Your healthcare provider can explain what your ratio means.
Can exercise increase ApoA1?
Yes, regular aerobic exercise is one of the most effective ways to raise ApoA1 and HDL levels.
