What is this test?
hs-CRP measures very low concentrations of CRP. In the absence of acute infection, it can complement the assessment of cardiovascular risk.
Why might it be ordered?
- As part of an overall assessment of cardiovascular risk in certain people.
- To measure low-grade inflammation when standard CRP is not sensitive enough for the specific purpose.
What sample is needed?
A healthcare professional collects a venous blood sample. Depending on the method, the laboratory uses serum or plasma.
How should you prepare?
Tell the laboratory about all medicines, hormone treatments, vitamins and supplements you take. Do not stop or change treatment unless your clinician tells you to. Follow any instructions about fasting and the time of collection.
How should you understand the result?
The value is interpreted with cholesterol, blood pressure, smoking, diabetes and other risk factors. Your result is interpreted using the reference interval on the laboratory report and in the context of your symptoms, medical history and other test findings.
