About Quest Diagnostics
Quest Diagnostics offers a range of laboratory services, including routine blood and urine tests, pediatric specialty tests, glucose tolerance testing, and wellness biometrics such as height, weight, and blood pressure. The location now provides COVID-19 antibody testing by appointment, though it is not available to those experiencing COVID-19 symptoms within the last 10 days. Face coverings are required at all sites. The lab is situated inside the Hacienda Shopping Center, inside Safeway near the pharmacy, with clear instructions on scheduling tests via their website. Patients often praise the professional and courteous staff, especially phlebotomists who deliver quick and painless blood draws. One technician was noted for her kindness, genuine concern, and ability to make the process comfortable. Another praised a technician for her skill in drawing blood from the arm, which can be challenging at times. Customers appreciate the friendly service and the staff's efforts to recognize returning patients and check on their well-being. However, some reviews mention challenges with the check-in system, which requires using a tablet upon arrival and is not well-advertised. During busy times, wait times can grow due to only one technician working, as the appointment slots are scheduled for 10 minutes each, though 15 minutes may be more realistic. The lab rooms are small but functional, with a waiting area and restroom. Overall, the location is seen as a clean, efficient, and friendly place for lab testing, with suggestions for improved check-in procedures and staffing to reduce wait times.
