Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Measurement of CRP by high sensitivity CRP assays may add to the predictive value of other markers used to assess the risk of cardiovascular and peripheral vascular disease.2-8
Increases in CRP values are nonspecific. CRP is an indicator for a wide range of disease processes 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 also be considered when interpreting results. Serial analysis of CRP should not be used to monitor the effects of treatment.
Immunochemiluminometric assay (ICMA)
Average hs-CRP level:1
• Low risk: <1.00 mg/L
• Average risk: 1.00-3.00 mg/L
• High risk: >3.00 mg/L
