This visit my blood draw took place in the 1st floor lab due to high volume. The lab tach chose my right arm for the draw. She missed the vein 7 times. She then used my wrist vein. During the process she held the tube 6" above my wrist and complained with the 2nd vial that the blood was slow. So I told her to lower the tube which then sped up the process. I have a 7"x3.5" bruise down my wrist. I will never allow this tech to touch me. I do not have her name but you can get it off my records.

Doctor didn't explain anything to me. And didn't introduce himself to me when he come in. I had to ask if he was the doctor. FRANKLY he didn't impress me much. 5 minute consultation is not enough time. He acted nervous. And really didn't listen to me. 5 minutes.
