How is the Test Performed?

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a tourniquet (elastic band) or blood pressure cuff is placed around the upper arm to apply pressure, which restricts blood flow through the vein.

This causes veins below the tourniquet to distend (fill with blood). A needle is inserted into the vein, and the blood is collected in air-tight vials or a syringe. During the procedure, the tourniquet is removed to restore circulation.

Once the blood has been collected, the needle is removed, and the puncture site is covered with gauze or a bandage to stop any bleeding.
