C-Reactive Protein Test – Normal Range

The normal range for c-reactive protein (CRP) is less than 1.0 mg per deciliter or less than 10 mg per liter.

CRP blood test can measure the content of c-reactive protein in blood.

Doctors use CRP tests to gauge the level of inflammation in the body, and elevated CRP levels usually mean a long-term illness or infection. Doctors use the test to monitor disease progression and therapeutic effects such as lupus, lymphoma, rheumatoid arthritis, giant cell arteritis or inflammatory bowel disease. Doctors can also use CRP blood tests to check for postoperative infections.

Blood levels of CRP are usually low. High or increased levels of c-reactive protein in the blood indicate the presence of inflammation, but do not determine its location.

In individuals suspected of having a severe bacterial infection, high CRP may be diagnostic. High levels of CRP in people with chronic inflammation indicate an exacerbation of the condition or a failure of treatment.
