Can you drink regular coffee before a CRP blood test?

Coffee contains caffeine, which can temporarily increase inflammation levels in the body. This could affect the accuracy of the CRP blood test, which measures the level of C-reactive protein (CRP) in the blood. High levels of CRP can indicate inflammation in the body.

Avoiding caffeine and certain foods and beverages for a period of time before a CRP blood test is recommended to ensure accurate results. Your doctor will provide specific instructions on what to avoid before the test.
