My doctor says that I need a blood test.
I can help you with that. Just have a seat and roll up your left sleeve.
What are you taking my blood for?
Your doctor has requested a check of your white blood count.
What information does that give him?
If your white blood cell count is off, it could signal an infection somewhere in your body.
Is a blood test painful?
I am putting a tourniquet on your arm to plump up the vein. It will only feel like a little pin prick.
Oh, my God, that hurts!
That was it! Thank you for coming in today.
