Measures C-reactive protein levels as a marker of systemic inflammation. Used to assess infection, inflammatory conditions, and cardiovascular disease risk.
CRP measures a protein your body produces in response to inflammation. Doctors order this test to screen for infections, assess inflammatory conditions like rheumatoid arthritis, or evaluate cardiovascular disease risk—especially when combined with other heart-health markers.
When elevated: An elevated CRP suggests active inflammation or infection somewhere in your body. This can indicate acute illness (such as bacterial infection or pneumonia), chronic inflammatory conditions (like rheumatoid arthritis), or cardiovascular risk. When low: A low CRP is generally favorable and suggests minimal systemic inflammation. Very low or undetectable levels are normal and expected in healthy individuals without active infection or inflammatory disease.
Elevated CRP can indicate excessive training stress, inadequate recovery, or underlying infection that may impair performance or increase injury risk. Some athletes monitor CRP trends to optimize training load and detect overtraining syndrome, though it's not specific enough to use alone for this purpose. Chronically elevated CRP also signals cardiovascular stress worth addressing for long-term health.
