C-Reactive Protein, High Sensitivity
Also known as: HSCRP
Use
Patients with higher hs-CRP concentrations are more likely to develop stroke, myocardial infarction, and severe peripheral vascular disease. CRP is a nonspecific marker of inflammation, and a variety of conditions other than atherosclerosis may cause elevated concentrations. If the first result is greater than 3.0 mg/L, recommend repeating the test at least 2 weeks later in a metabolically stable state, free of infection or acute illness. The lower of the two results should be used to determine the patient's risk.
Special Instructions
Not recommended for general cardiovascular disease risk assessment in asymptomatic adults. May aid in CVD risk stratification in specific populations.
Limitations
CRP is a nonspecific marker of inflammation and the test cannot differentiate between causes of elevated levels. Significantly decreased CRP values may result from patients treated with carboxypenicillins. This test is not recommended for general cardiovascular disease risk assessment in asymptomatic adults.
