A simple score from triglycerides and HDL that hints at how plaque‑forming your blood fats may be.
The atherogenic index of plasma (AIP) is a calculated value, not a separate blood test. It is the base-10 logarithm of triglycerides divided by HDL cholesterol, with both in mmol/L. It reflects the balance of triglyceride-rich and protective lipoproteins, and indirectly the size of LDL particles.
A higher AIP suggests more small, dense, harmful LDL particles and a more atherogenic lipid profile. It has been studied as a predictor of cardiovascular risk and is often more informative than triglycerides or HDL alone. It is a research-derived index used alongside the standard lipid panel.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
These are interpretive cut-offs from research, not lab ranges, and the calculation requires SI units (mmol/L).
| AIP value | Interpretation |
|---|---|
| Below ~0.1 | Lower cardiovascular risk |
| ~0.1 to 0.24 | Intermediate risk |
| Above ~0.24 | Higher cardiovascular risk |
Triglycerides change with recent meals, alcohol, and illness, so a non-fasting sample can raise AIP. Pregnancy and some medicines also shift the components. The index must use mmol/L, since using mg/dL gives a different number.
Best read with its components, triglycerides and HDL cholesterol, plus LDL, ApoB, and overall cardiovascular risk.
What does my result mean? Higher values suggest a more plaque‑promoting lipid pattern; lower values suggest the opposite. Always view it with your full cholesterol profile.
Do I need to fast? Fasting is not required for this index. Your clinician may ask for a fasting repeat if triglycerides are very high.
What can affect the result? Recent alcohol, big fatty meals, illness, intense exercise, and many medicines can shift triglycerides and HDL.
How often should I test it? Many people recheck with routine lipid panels, often every 3 to 12 months, or after changing lifestyle or medications.
How quickly will I get results? Results are usually ready in about 7 days.
What should I discuss with my clinician? Review LDL or ApoB targets, overall heart risk, and steps to improve triglycerides and HDL if needed.
