I had an early morning appointment and I was in and out of there in 5 minutes. Siper easy check in and the staff was great!

Must have been my lucky day. I was a midday walk-in patient, prepared to wait for an opening. Thanks to a no-show, I was in and out within 30 min. The phlebotomist was personable and it was a successful draw. Still awaiting results a week later. Not sure what the norm is.
