Booking appointments with Quest is a breeze. You can do it right after you’re done placing an order.
It's that simple!
You’ll see the option to cancel/reschedule the appointment in the confirmation email that you’ll receive after scheduling the appointment.
You can book your appointment here: https://www.labcorp.com/labs-and-appointments
Same as Quest, you should be able to cancel/reschedule from the email or find instructions to reschedule or cancel on the confirmation you received. Once on the LabCorp page, this box will be located to the bottom right of the page. This is also the same way to schedule an appointment.
