A: The doctor sent me over here to have my blood drawn. B: Certainly, please have a seat and roll up your left sleeve. A: What is this test for? B: Well, today your doctor wants us to check your white blood cell count. A: What does that tell him? B: Well, if it is elevated, you might have an infection. A: Will the blood test hurt? B: It is only a little pin stick. I am going to put a tourniquet on your arm to puff your veins up. A: Ouch! B: There we go! I got the blood that I needed.
