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, may cause elevated CRP levels, and should also be considered when interpreting results.  For assessing cardiac risk, a highly sensitive assay should be ordered.
