Low C-Reactive Protein (CRP): what it means
A C-Reactive Protein (CRP) result below the normal range is considered low. Here is what a reduced C-Reactive Protein (CRP) can point to, and when it is worth discussing with a doctor.
Reference range: <3 mg/L low cardiovascular risk; >10 mg/L active inflammation
Understand your full resultWhat a low C-Reactive Protein (CRP) can mean
- No active inflammation — the expected state in healthy adults.
- A low CRP is a strong negative predictor — useful for ruling out bacterial infection in primary care.
When to discuss with a doctor
CRP above 100 mg/L typically indicates a bacterial infection or major inflammatory process and warrants prompt evaluation. Persistent values in the 10–40 range warrant a primary-care work-up for autoimmune disease, chronic infection or malignancy. For cardiovascular risk, hsCRP >3 mg/L on two readings without acute cause is associated with elevated 10-year risk and may guide statin decisions.
