Labcorp cannot find lab order. This occurred three time in past 12, months. Scheduling an appointment is unacceptable secondly after arriving for scheduled visit for routine lab work the Labcorp assistant say they cannot find lab order. I call my doctors office ( John Muir Medical )and was told the order is in the system but Labcorp states they cannot find it. This has occurred three times to me in the past 12 months. I am also com[plaing about their scheduling process. Very cumbersome to schedule an appointment. Locations randomly closed.
