What it is

A CRP test measures C-reactive protein, which the liver makes when there is inflammation in the body. It is used to look for infection or inflammatory conditions and to follow how they respond to treatment.

What the price covers

The price usually covers the CRP test only. The blood draw is often billed separately.
