During a blood test, a healthcare professional will:
1. Clean the area where the blood will be drawn, usually the inside of your elbow. 2. Apply a tourniquet to make your veins more visible. 3. Insert a needle to draw blood into one or more vials. 4. Remove the needle and apply a bandage to the site.
The process is generally quick and minimally painful, although you may feel a slight pinch.
