HelpTest Code LAB3588 C-Reactive Protein (CRP) High Sensitivity, Cardiac Risk, Plasma or Serum
Additional Codes
| Test Name in EPIC | EPIC Test Code | Mnemonic |
|---|---|---|
| CRP HI SENS CARD | LAB3588 | CRPHS |
Useful For/Utility
Useful as an aid in identification and stratification of individuals at risk for cardiovascular disease. When used in conjunction with traditional clinical laboratory evaluation of acute coronary syndromes, Cardiac CRP may be useful as an independent marker of prognosis for recurrent events, in patients with stable coronary disease or acute coronary syndrome.
Methodology
Turbidimetric/Immunoturbidimetric
This test is recommended for cardiovascular risk assessment only.
Clinical Information
Studies have shown that measurement of CRP using a sensitive assay is a strong independent predictor of risk for future cardiovascular and peripheral vascular disease.1 CRP measurements have also been shown to add to the predictive value of other markers used to assess the risk of cardiovascular and peripheral vascular disease.2-4 Elevated CRP values determined by Cardiac CRP may be indicative of the prognosis of individuals with acute coronary syndromes, and may be useful in the management of such individuals.
Specimen Requirements
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Plasma
Container/Tube: Light-green top (lithium heparin gel)
Specimen Volume: 1 mL
Specimen Minimum Volume: 0.5 mL
Collection Instructions:
1. Separate plasma from cells within 2 hours of draw.
2. If plunger filters are used, immediate removal of plasma is indicated unless an air gap can be created between the device and specimen.
Additional Information: Label specimen appropriately (plasma).
Alternate:
Specimen Type: Serum
Container/Tube: Red top with clot activator or serum gel
Specimen Volume: 1 mL
Specimen Minimum Volume: 0.5 mL
Collection Instructions:
1. Separate serum from cells within 2 hours of draw.
2. If plunger filters are used, immediate removal of serum is indicated unless an air gap can be created between the device and specimen.
Additional Information: Label specimen appropriately (serum).

Reference Values
0-3 mg/L
RELATIVE RISK CATEGORIES FOR CORONARY HEART DISEASE
Low: 0-1 mg/L
Average: 1-3 mg/L
High: >3.0 mg/L
Values >14 mg/L may indicate an underlying inflammaory condition, and this result should not be used to assess coronary risk. Repeat testing after resolution of inflammatory condition is suggested.
