CRP Blood Test

May 4, 2026

CRP Blood Test

A CRP (C-reactive protein) blood test measures levels of this inflammation marker in your blood—produced by the liver in response to inflammation from infection, injury, autoimmune disease, or chronic low-grade inflammation that increases cardiovascular risk. CRP is one of the most useful general markers for detecting that something inflammatory is happening in your body.

At Blood Test London, CRP testing costs from £245 with results in 2-3 days. A doctor always reviews every result.
