Drop off your specimen shortly after collection (within 2 hours). Drop off your sample in the drop off bin adjacent to the vending machine. Your sample will be picked up on weekdays at 3:00 pm. Samples submitted after that time will be collected on the following collection day. Samples should not be dropped off from Fridays at 3:00 pm to Sundays at 3:00 pm. Samples provided during this period will become expired and rejected by the lab.
