    The phlebotomist who assisted me was cordial, but it became clear he was just doing as quick of a job as possible. Multiple bothersome observations: He didn't wash his hands before putting on gloves (I work in food service and even for food safety, I know how ridiculous it is to not wash hands before gloves: You are literally touching the outside of the gloves with your dirty hands when you put them on.) Then, just before he stuck the needle in, he needed to cough; which he did directly in front of me and ONTO HIS GLOVED HAND. Finally, when he removed the needle and put a cotton ball on the site, instead of putting a small piece of first aid tape, he WRAPPED THE TAPE AROUND MY ARM. Twice. When I took it off 15 min later, it literally ripped the hair off my arm. I'm 8 months pregnant so when a health professional does unsanitary things, it doesn't only bother me for my health, but my baby's as well. Unfortunately I do not know the name of my phlebotomist, but if Quest responds to this and cares to have a conversation with their employee, I'm happy to provide my full name & info so they could check who assisted me.

    My appointment was great. Very easy to set up my appointment on line, and I arrived I check in with my phone and they call me on time. The location is perfect for people in Sugar Land, Missouri City, Stafford. Is one of the few locations of quest that open early 6 a.m. I recommend this location
