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.
Your doctor will discuss what your CRP test result means. If you're having an hs-CRP test to evaluate your risk of heart disease, these are the current risk levels used: 1  Low risk. 2  You have a CRP level of less than 1.0 milligram per liter (mg/L). 3  Average risk. 4  You have a CRP level between 1.0 and 3.0 mg/L. 5  High risk.
