C-Reactive Protein (CRP) is an inflammatory marker produced by your liver in response to injury, infection, or systemic inflammation. This blood test measures the concentration of CRP to assess your body's inflammatory state.
CRP is ordered to detect or monitor acute infections, inflammatory conditions, or chronic low-grade inflammation. It's also used to assess cardiovascular disease risk, since elevated CRP correlates with atherosclerosis and heart disease.
When elevated: An elevated CRP level indicates active inflammation somewhere in your body, which may signal infection, autoimmune disease, heart disease, or other inflammatory conditions. The higher the level, the more significant the inflammatory response, though CRP alone cannot pinpoint the cause. When low: A low CRP level is generally favorable and suggests minimal systemic inflammation. Low levels are typical in healthy individuals without active infection or inflammatory disease.
Athletes use CRP to monitor training-induced inflammation and recovery status; elevated levels may indicate overtraining, inadequate recovery, or underlying infection that could impair performance. Chronically elevated CRP can signal systemic inflammation that compromises health and longevity, making it relevant for long-term athletic sustainability.
