How is a blood test performed in the lab?

Depending on the symptoms you are experiencing, your doctor may order a APTT and RBC test. In most hospitals APTT and RBC results can be obtained within three to six hours after blood is taken. The blood is usually drawn from a vein on the inside of the elbow or the back of the hand. Drink plenty of water before your appointment. If you experience any symptoms that you are concerned about are out of the ordinary, call your doctor immediately.
