【健康】进行血液检测-Having a Blood Test in the Lab（打印版）

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.
