Meconium Methadone Screen

Specimen Type Describes the specimen type needed for testing

Meconium

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.

Collect specimen into the same leak proof, sterile plastic collection vial until 3 g of meconium have been collected or until the first milk stool appears. Between collections, store specimen in a secure refrigerator. When at least 3 g of meconium has been collected, tightly screw on the cap of the collection vial and send specimen refrigerated.

 

Note: Specimens from different voiding may be pooled if necessary.

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.
