Quest Diagnostics in Willow Plaza offers routine lab tests, blood and urine testing, drug screens for DOT and non-DOT purposes, pediatric specialty services, glucose tolerance tests, and COVID-19 antibody testing by appointment. The entrance is located between Sherwin Williams and Nikko Nail Salon in suite 700. Appointments can be scheduled online, with specific hours for drug screens and TSPOT tests. Many patients report friendly, skilled, and helpful staff, with efficient service leading to little or no wait time. The online appointment system is generally easy to use, and self check-in is fast. However, some customers experience frustrations with the software and check-in process. Issues include difficulty storing insurance information, problems with appointment confirmations and QR codes, and challenges with canceling appointments or opting out of reminders. Occasionally, doctor's orders do not appear in the system promptly, causing confusion. The location is noted by some as being understaffed. Management has been commended for being responsive and helpful in establishing special, urgent orders. Patients are advised to visit the website for test preparation tips and scheduling.
