I called the lab on Thursday the 25th of May. I was greeted by a young woman who answered my questions, and told me no appointment was needed for a fasting blood draw there. Today (26 May) I went to the laboratory and was greeted warmly by the receptionist, signed in and within 10 minutes was taken to the drawing station. The phlebotomist, Ilina, was courteous and professional. She checked all the paperwork and labeled the specimens and had me check for accuracy. I am very impressed by the staff and the cleanliness of this Sonora Quest Lab Facility.
