A simple ratio comparing inflammation (CRP) to good HDL cholesterol to add heart-health context.
The CRP/HDL ratio is a calculated value, not a separate blood test. It is C-reactive protein (a marker of inflammation) divided by HDL cholesterol (a protective lipoprotein). It combines an inflammation signal with a lipid signal in one number.
A higher CRP/HDL ratio means more inflammation relative to protective HDL, a combination linked in research with higher cardiovascular and metabolic risk. It is an emerging research index rather than a routine clinical test, and is read alongside the underlying CRP and HDL values.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
This is an emerging research index with no firmly established clinical cut-off. It depends on whether standard or high-sensitivity CRP is used and on the units, so it is best read as a trend with its components.
| Pattern | Interpretation |
|---|---|
| Higher ratio | More inflammation relative to HDL; studied as higher risk |
| Lower ratio | Less inflammation relative to HDL |
Thresholds are not standardised. Source: CRP to HDL ratio and cardiometabolic risk research.
CRP rises sharply with any infection, injury, or recent illness, which can transiently inflate the ratio. HDL changes with diet, alcohol, exercise, and some medicines. A recent cold or vaccination can make the result misleading.
Best read with its components, high-sensitivity CRP and HDL cholesterol, plus the full lipid panel.
What does a high or low CRP/HDL mean? A higher ratio points to more inflammation relative to your HDL level. A lower ratio suggests less inflammation compared with your HDL.
Do I need to fast for this test? Fasting is not required. If your clinician asked for a fasting lipid panel, follow their instructions.
What can affect my result? Illness, recent vaccines, hard workouts, smoking, alcohol, dehydration, pregnancy, and medicines like statins or steroids can shift results.
How often should I test it? Many people recheck every few months when adjusting lifestyle or treatment. Your clinician can suggest a timing that fits your risk.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Review your hs-CRP, full lipid panel, family history, symptoms, and habits. Ask how this ratio fits your overall heart-risk plan.
