Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

10 mL random urine, after collection add 6N HCL to maintain a pH below 3. Submit in a sterile screw capped container shipped ambient.


Note: 1. Urine without preservative is acceptable if pH is below 6 and shipped frozen.

         2. Dietary Instructions:

             - Patient should avoid food high in indoles: avocado, banana, tomato, plum, walnut, pineapple, and eggplant.

             - Patient should also avoid tobacco, tea and coffee three days prior to specimen collection.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
