Inflammation & Immunity

CRP Test (Inflammation)

C-reactive protein — the most common marker of inflammation in the blood.

A CRP test measures C-reactive protein in your blood, a marker that rises with inflammation. A high-sensitivity CRP (hs-CRP) test can also be used as part of cardiovascular risk assessment.

What it measures

CRP

Standard C-reactive protein — rises with infection, injury or chronic inflammation.

hs-CRP

High-sensitivity CRP — used to detect low-grade inflammation linked to cardiovascular risk.

Why it matters

Chronic low-grade inflammation is linked to cardiovascular disease and metabolic conditions.
Acute infections or injuries can raise CRP dramatically — clinicians usually retest once recovered.
Results are most useful alongside other markers such as cholesterol and HbA1c.

How testing works

Order CRP or hs-CRP as a standalone test or as part of a wellness panel.
Avoid testing within 1–2 weeks of an acute illness or injury for a true baseline.
Results are typically returned in 2–4 working days.

Frequently asked questions

What is a normal CRP level?

Standard CRP is usually under 5 mg/L in healthy adults. For hs-CRP, a level under 1 mg/L is considered low cardiovascular risk, 1–3 mg/L moderate risk and above 3 mg/L higher risk.

What raises CRP?

Infection, injury, autoimmune conditions, obesity and smoking can all raise CRP. Even an intense workout can transiently elevate it.
