Maybe it is just the thought.. it looks like a lot of blood, but its not that much...
got this from yahoo...someone asked about getting 3 vials drawn..
The volume of blood that a Vacutainer tube draws out of you is small, and can range from about 1 ml (for the tiny pediatric tubes) to about 10 ml for the normal sized tubes. There may be larger ones that I'm not familiar with.
The three tubes that were withdrawn from you represent about 30 ml at the most, which is one ounce (like a small medicine cupful)
In contrast, blood donation is about a pint, or 450-500 ml (they actually weigh the blood, so the volume varies), and that's about 10% of what most people have in their bodies.
I. am. not. a. doctor.
