Apolipoprotein A1 (Apo A1)
Apo A1 is the main protein on HDL particles. Measuring the protein offers a different view of lipid transport from measuring the cholesterol inside HDL.

Understanding the test
What does Apolipoprotein A1 (Apo A1) measure?
Also called HDL Structural Protein
Apo A1 may be considered when the routine lipid profile leaves a cardiovascular risk question unresolved. Family history may influence the decision to test.
When it may be requested
An HDL-related question
The protein concentration can provide context when HDL cholesterol is unusual.
A wider lipid assessment
A clinician may compare Apo A1 with Apo B and other cardiovascular risk factors.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
No fast is generally needed for Apo A1 alone. Follow lipid-panel fasting instructions if other lipids share the draw, and note any recent acute illness.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
The protein concentration adds information about HDL-associated transport. A single measurement cannot assess the function of each HDL particle.
What can affect it
- Apo A1 measures a protein concentration. It neither counts HDL particles directly nor measures how well they function.

Patient questions
Before you book
Is Apo A1 the same measurement as HDL cholesterol?
No. One measures protein and the other measures cholesterol. They often move together, but the results have different units and answer different questions.
Can I raise my Apo A1?
Regular aerobic exercise, stopping smoking, losing excess weight and improving triglycerides all tend to raise it. Medicines that raise it directly have not been shown to reduce heart attacks, so lifestyle remains the practical route.
Does a good Apo A1 cancel out a high Apo B?
No. They describe opposing processes but do not offset one another. Your doctor looks at both, and often at the balance between them, rather than letting one excuse the other.
