Apolipoproteins Profile (A1, B & Ratio)
This profile reports Apo A1, Apo B and their ratio. It compares two different sides of lipid transport in one blood sample.

Understanding the test
What does the Apolipoproteins Profile (A1, B & Ratio) test measure?
Also called Apo A1 / Apo B Ratio Panel
A clinician may request both proteins when evaluating a mixed lipid pattern. The ratio shows their relationship while the individual values show what drives it.
When it may be requested
One pair of protein results
Seeing each value helps explain what drives the ratio.
A family history
When cardiovascular disease occurred early in the family, the protein profile may add context to routine lipids.
Inside this test
What the laboratory looks for
Panel components
- Apolipoprotein B (Apo B)
- Apolipoprotein A1 (Apo A1)
- Apo B/Apo A1 ratio (calculated)
Before your sample

Your checklist
The apolipoprotein pair itself usually needs no fast. If a full lipid panel is also being drawn, follow its preparation and bring your previous lipid or Apo results.
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
A change in either protein can move the ratio. The clinician therefore looks at the numerical pair as well as the ratio and your other cardiovascular risk factors.
What can affect it
- A ratio may conceal different changes in its numerator and denominator.

Open your laboratory report
Look for Apolipoproteins Profile (A1, B & Ratio) in your report. Use the sample type and collection time when comparing it with an earlier report.
Explore Smart Report
Discuss the next step
Ask which component explains the ratio. A discussion of Apo A1 and Apo B separately can be more informative than tracking the ratio alone.

Patient questions
Before you book
Does the ratio show whether an artery is blocked?
The ratio helps assess risk over time. It cannot show an obstruction or locate plaque in an artery.
Why report a ratio rather than the two results on their own?
The ratio condenses the balance between cholesterol delivery and removal into one figure that has tracked risk well in large studies. The individual results are still reported, because the same balance can arise in very different ways.
What if my Apo B looks good but my Apo A1 is low?
A low Apo A1 means there is less of the main HDL protein in your blood. The test measures an amount of protein, not how well your HDL works. Your clinician interprets both protein levels alongside your LDL cholesterol and other heart risk factors when discussing treatment.
