Testing begins with immunoassay screen. Positives are confirmed and quantitated by liquid chromatography-tandem mass spectrometry (LC-MS/MS) at an additional charge.
Chain of Custody is recommended for this test. Chain-of-Custody Meconium Kit (T653) is available upon request.
Container/Tube: Stool container (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 (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.
