To collect the 5-10 ml of blood needed for this test, a healthcare worker ties a tourniquet on the patient's upper arm, locates a vein in the inner elbow region, and inserts a needle into that vein. Vacuum action draws the blood through the needle into an attached tube. Collection of the sample takes only a few minutes.
The patient should avoid strenuous exercise and have nothing to eat or drink, except water, for eight to ten hours before this test.
— Nancy J. Nordenson
