World MS Day @WorldMSDay. May 30th 2018. Bringing the world together to campaign with & for everyone affected by multiple sclerosis. An initiative of the MS International Federation.
Why It Is Done. A C-reactive protein (CRP) test is done to: 1  Check for infection after surgery. 2  CRP levels normally rise within 2 to 6 hours of surgery and then go down by the third day after surgery. 3  If CRP levels stay elevated 3 days after surgery, an infection may be present.
However, the high sensitivity CRP (hs-CRP) test measures very small amounts of CRP in the blood and is ordered most frequently for seemingly healthy people to assess their potential risk for heart problems. It typically measures CRP in the range from 0.5 to 10 mg/L. The regular CRP test is ordered for those at risk for infections or chronic inflammatory diseases (see above). It measures CRP in the range from 10 to 1000 mg/L.
