Always make a 7 AM appointment (for fasting tests) and usually get called in within 5 minutes of appointment time. Consistently good. We always go to the location at Lake Mead and Buffalo. Staff is pleasant and competent.\nOf course, today I called to get the results and was told that one test was still \""pending\"". The lab didn't receive the specimen until after midnight today despite the fact that the blood draw was taken at 7 AM yesterday. That's the last time I make an appointment for a Friday :-).\nOtherwise, I recommend this location highly.
