Question about blood tests?

I am a tech and am pretty good at it. It usually does not hurt, but there are no guarantees in life. Go in with a good attitude about it. Dont move and do whatever the tech tells you to do. The quicker the tech can start, the quicker they can finish. 1 stick should get all the blood needed, unless you are flopping around in the chair and you make the needle come out the vein. Then it may take 2 sticks. Really up to you. Also, drink plenty of water the day before to get well hydrated, that makes it easier sometimes.
