Urine drug tests require either 30 or 45ml of specimen. If a donor is not able to produce sufficient specimen, the shy bladder process is begun.
A donor is permitted up to 3 hours and up to 40 ounces of water. Most are able to produce a specimen in 20-30 minutes. Water is provided by staff and logged. All attempts to provide a specimen are also logged. Donors are not required to drink the water.
After 3 hours, if the donor does not provide a specimen, the donor is dismissed and we report the event to the MRO and to the employer. For DOT collections, the MRO will request the donor to provide a medical explanation. If none is provided, it becomes a Refusal to Test. Non-DOT employers treat it according to company policy.
