3 mL FROZEN URINE Light Protected in an Amber tube or foil wrapped
On collection of random urine, it is advisable NOT to use first voided morning specimen, late evening specimen after 8 PM, or specimen obtained following excessive fluid intake. Transfer the urine into a plastic AMBER frozen transport tube with amber cap. If ordered with delta ALA, pH must be <6. Label the container with the patient's name and date. The specimen should be FROZEN immediately and maintained frozen until tested. (If amber tube and cap are not available, cover a clear plastic transport tube COMPLETELY from top to bottom with aluminum foil. Identify the specimen with the patient's name directly on the transport tube AND the outside of the aluminum foil. Secure with tape. To avoid delays in turnaround time when requesting multiple tests on frozen samples, PLEASE SUBMIT SEPARATE FROZEN SPECIMENS FOR EACH TEST REQUESTED.
