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.

Submit only 1 of the following:


-Collect 1 24-hour urine with 6N HCL added at the beginning of collection.

Mix well and submit 4 mL aliquot. Ship refrigerate.


-Collect 24-hour urine without preservative. Submit 4 mL aliquot.

Ship refrigerate.


Note: 1. Total Volume required

              2. Avoid direct sunlight

              3. Avoid taking allergy causing drugs, antihistamines, oral

                   corticosteroids, and substances which block H2 receptors

                   for at least 24 hours 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.
