Test ID: FPMET
Prometheus Thiopurine Metabolites
Specimen Type 
Describes the specimen type needed for testing
Whole Blood EDTA
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.
Draw 5 mL EDTA whole blood. Submit EDTA whole blood promptly
at refrigerated temperature.
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.
Pediatric Minimum Volume: 3 mL
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
