    I always prefer to use Quest diagnostics whenever possible... as I have never had a negative experience there. I do recommend making an appointment ahead of time, as I did for this blood draw. The whole experience was very satisfactory, and I was actually called in for the blood draw 10 minutes before the appointed time... In my 77 years of experience, I have found that many times it pays to arrive for an appointment a few minutes early, which I did this time, and I was first on the list, as no one else was waiting.

    These people made the absolutely careless mistake of putting Fentanyl on my labs. They said it could be a mistake, but that's one heck of a mistake to make. Avoid this place like the plague.

    Scheduled an appointment online with ease. Arrived on time for appointment at 1:40 and was out by 1:47. The phlebotomist was TOP NOTCH. She was professional, efficient, gentle, and quick: all things you are looking for in this profession. I read the poor reviews and have realized people love leaving only negative experiences so I decided to be sure and leave my POSITIVE experience. Thanks for making this dreaded task a comfortable one!

    The Quest phlebotomist was courteous, inviting and made me feel welcome. She let me know at each step of the way what was going to happen. I highly recommend Quest to friends, family and acquaintances. --Silveria
