It’s an inflammation biomarker. CRP is a protein produced by your liver. Typically, your blood contains low levels of CRP. However, if you have inflammation in your body, your liver releases more CRP into your bloodstream. Elevated CRP levels may indicate a serious health condition associated with inflammation. However it can not pinpoint where the inflammations are happening if they are inside the body.
