Keystone Lab

Keystone Laboratory is open to serve our community in this difficult time. We are committed to helping our partners provide the highest quality patient care. This means opening our doors to your patients for toxicology testing. We understand that many of your locations are temporarily unable to provide drug screening collections and Keystone is here to help. We are happy to handle your routine collections at our Laboratory in Asheville so that you may continue to provide reliable treatment, and your patients have a continuity of service from your practice.
