Outage notice:

Due to the global information outage that occurred Friday, Quest is taking swift action to respond, recover and restore our operations. Our Patient Services are operating with reduced capacity so you may experience longer wait and service times. Our Customer Contact teams are currently unavailable. We appreciate your patience as we work toward returning to normal operations.
