C-Reactive Protein
Alternate Names : CRP
How is the Test Performed?
Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band or blood pressure cuff is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to swell with blood.
A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
CRP is detected with the use of antiserum (serum that contains antibodies for a particular antigen) in several tests that measure the protein and protein-bound molecules.
