1. Is hs-CRP specific for predicting heart disease?
Since CRP is a marker of
inflammation, its elevation may reflect a low level of inflammation that may manifest in the future in different ways. Most studies to date have focused on
heart disease, but new research shows that having CRP in the high normal range may also be associated with other diseases such as
colon cancer, complications of
diabetes, and obesity.

2. I have had cholesterol tests but never an hs-CRP test. Why?
The traditional testing methodology for
CRP has been available for a number of years; however, the hs-CRP test is fairly new, and experts still don't agree on when and how often this test should be ordered. As more clinical studies are completed in addressing cardiovascular problems, this test may be more frequently ordered.

3. What is the difference between regular CRP and hs-CRP tests?
Both tests measure the same molecule in the blood. The hs-CRP test is for seemingly healthy people to determine their risk of
cardiovascular disease. It measures CRP in the range from 0.5 to 10 mg/L. The
CRP test is ordered for patients at risk for
bacterial or
viral infection (such as following surgery) or patients with
chronic inflammatory diseases (such as
rheumatoid arthritis). It measures CRP in the range from 10 to 1000 mg/L.
