    Make an appointment to drop off urine samples. Otherwise, you wait as a walk-in 30-60 mins+ while the sample deteriorates past your doctor's 1 hr drop off timeline.

    Danny was great! I was even taken in early. Maybe 20 minutes total time from parking to leaving. I applaud the service I received.

    Quest test did not specify 7am to 9am window for one of the tests. This forces me to return for another appointment. This could have been avoided if proper test requirements were communicated.
