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.
A high-sensitivity CRP (hs-CRP) test measures low levels of CRP using laser nephelometry. The test gives results in 25 minutes with a sensitivity down to 0.04 mg/L.RP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes). It is a member of the pentraxin family of proteins. It is not related to C-peptide (insulin) or protein C (blood coagulation).
