    The lab technicians/employees are always so nice and thorough. The wait usually isn't too long depending on the time you get there but they always move quickly.

    Female employee asked to raise my sweater so she can see my waistline, for a URINE sample. That alone is a violation. Lawsuit is on its way

    I love the Quest - Alton location. All of the ladies I've encountered have been very sweet, thorough, and efficient. I would suggest making an appointment though, because I've never been there and it not be booked and busy. All the people saying that they waited a long time were due to not making an appointment and being a walk in.
