Quest Diagnostics is a healthcare provider that offers a range of services, including COVID-19 antibody testing, drug screenings, routine lab tests, and more. The company has a location near the corner of Lockwood Avenue and Sickles Place, though the entrance is actually on Van Guilder Avenue, which can be confusing for some patients. Overall, reviews of this Quest Diagnostics location are mixed. While some patients report quick and efficient service, with a friendly nurse who was able to draw blood without causing any pain, others note that the facilities appear old and run-down, with poor signage and a lack of staff at the reception area. One reviewer mentioned that the nurse seemed frazzled and overworked, suggesting the appointment schedule may be too packed. Despite these criticisms, many patients seem satisfied with the care they received. One reviewer who was initially hesitant due to negative reviews ended up having a positive experience, praising the nurse's kindness and professionalism. Another simply described the experience as "perfectly fine," noting that they were in and out in less than 10 minutes. While Quest Diagnostics could benefit from some improvements to its facilities and patient flow, the company appears to provide generally competent and reliable healthcare services to the local community.
