|Note: ||INTERPRETIVE INFORMATION FOR CRP, HS (hsCRP): |
CRP is a non-specific indicator for a wide range of disease processes. Increases in CRP values are non-specific and should not be interpreted without a complete clinical history. Recent medical events resulting in tissue injury, infections, or inflammation, which may cause elevated CRP levels, should be considered.
Follow-up testing of patients with elevated CRP values should be performed. Patients with persistently unexplained CRP levels above 10 mg/L after repeated testing should be evaluated for non-cardiovascular sources of infection or inflammation.
