Cholesterol Tests (cont.)

During the Procedure
During this procedure, a blood sample will be taken from a vein in your arm. To do so, a tourniquet (an elastic band) is tied around your arm just above the elbow. A needle is then inserted into a vein in your arm near the inside of your elbow. Once the needle is positioned, a small amount of blood is withdrawn and collected in a vial or a syringe. After the blood is collected, the needle is removed from the vein, and the tourniquet is removed from your arm. A small cotton ball is pressed over the puncture site to stop any bleeding. A bandaid may be placed to protect clothing should a small amount of blood leak out of the puncture site.
