A highly sensitive blood test that reflects low-grade inflammation and helps refine heart risk.
hs-CRP is a high-sensitivity test for C-reactive protein, a marker your liver releases when there is inflammation in the body. The high-sensitivity version can detect the low levels that matter for heart risk.
Unlike standard CRP, which is used for infections, hs-CRP is used to pick up the low grade, ongoing inflammation linked to cardiovascular disease.
A raised hs-CRP, once infection and recent illness are ruled out, points to low grade inflammation that adds to the risk of heart attack and stroke. It is used alongside cholesterol to refine cardiovascular risk.
A low hs-CRP is reassuring. Because the value can jump with any infection, it is usually repeated and read when you are well.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
| Cardiovascular risk | hs-CRP (SI) |
| Lower risk | below 1.0 mg/L |
| Average risk | 1.0 to 3.0 mg/L |
| Higher risk | above 3.0 mg/L |
Ranges are guidance only. Values above 10 mg/L usually reflect an active infection or illness rather than heart risk, and the test should be repeated. Read against your own lab's interval.
Any recent infection, injury, surgery, or flare of an inflammatory condition raises hs-CRP sharply, so test when you are well. Obesity, smoking, and pregnancy raise it, while statins and exercise can lower it. Fasting is not required.
Read alongside the lipid panel (LDL and HDL) and HbA1c to build an overall cardiovascular and metabolic risk picture.
What does an hs-CRP result mean? It reflects the level of low-grade inflammation in your body. Higher values suggest more inflammation and may signal higher heart risk.
Do I need to fast for hs-CRP? No. Fasting is not required. Testing when you’re well gives the most useful result.
What can affect my result? Illness, recent vaccination, injury, hard workouts, smoking, pregnancy, and some medicines can raise or lower hs-CRP.
How often should I test? Many people repeat it in 2 to 3 weeks if elevated, or every 3 to 12 months to track trends, based on clinician advice.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Share any recent illness, exercise, or new medicines, and review your overall heart risk and next steps.
