How much blood will be drawn?

0

Less than one ounce of blood is drawn from a vein and collected into a few vials. Please advise the examiner if you have had previous problems such as nausea, fainting, bruise easily, have difficulty clotting or are currently taking any medication.

We know it looks like a lot, but it’s really not! A typical tube holds about 1 teaspoon of blood. A typical person has about 14 pints of blood in their body, which is about 1,344 teaspoons. Even if we draw more than one tube of blood, you can see that it’s not very much compared to how much you have in your body.
