Quest Diagnostics offers COVID-19 antibody testing by appointment, along with routine blood and urine testing, pediatric specialty services, and wellness programs. The facility is located in the Dignity building behind Mercy General Hospital, with an entrance on the first floor. Appointments can be scheduled online. Reviews note that staff members are often gentle, careful, and patient when drawing blood, with some going above and beyond to assist patients. The check-in process is automated using a kiosk that scans identification and insurance cards. Wait times are frequently reported as short, with patients sometimes seen earlier than their scheduled appointment. Patients are advised that sharing lab results with non-ordering doctors is now the patient's responsibility.
I liked the experience at the clinic and the staff are great. However I can not recommend this location due to the parking situation you have to pay for parking. Also finding the place is a hassle and very difficult.

The walk in service at Mercy San Juan Downtown was exceptional. Imelda was very thorough and my Lab results were process for next day appointment.
