I am sorry that you were not satisfied with the laboratory that processed your specimen and that you needed to have your blood drawn a second time so that the laboratory could produce a result. Your feedback is important because we are not the laboratory but the phlebotomist that collect the specimen and send it to a clinical laboratory. Because we use the sterile equipment provided by laboratories, it is impossible to obtain a contaminated specimen. The vacutainers provided automatically stop when they are filled. I do not believe you have laboratory experience as you would not have made such an accusation. If you contacted the office an asked to speak to management your questions would have been explained. I am proud of my staff and the quality of their work. they are compassionate and thoughtful. We also realize that our patients are sick and often suffering and we keep that in mind even if they complain.
