Drugs of Abuse Screen, Meconium 5
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.
Chain of Custody is recommended for this test. Chain-of-Custody Meconium Kit (Supply T653) is available upon request.
Container/Tube: Stool container (Supply T288)
Specimen Volume: 1 g (approximately 1 teaspoon)
Collection Instructions: Collect entire random meconium specimen.
1. For chain-of-custody information, see Chain-of-Custody Meconium Kit (Supply T653).
2. Specimen that arrives with a broken seal does not meet the chain-of-custody requirements.
3. The laboratory recommends sending chain-of-custody specimens by overnight shipment.
4. If heroin use is suspected, specimen must be sent frozen to prevent loss of 6-monoacetylmorphine (6MAM, heroin metabolite). When refrigerated, a significant percentage of 6MAM will convert to morphine in <24 hours.
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.
0.45 g (approximately 0.5 teaspoon)
Grossly bloody reject; Pink OK
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
