Test ID: AFBIL    
Bilirubin, Amniotic Fluid

Specimen Type Describes the specimen type needed for testing

Amniotic Fld

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.

Collection Container/Tube: Amniotic fluid container

Submission Container/Tube: Opaque, amber vial (Supply T192)

Specimen Volume: 3.5 mL

Collection Instructions:

1. Centrifuge, separate supernatant, and send both supernatant and sediment in separate opaque, amber vials to protect from light.

2. Label specimens as sediment and supernatant.

Additional InformationGestational age at time of amniocentesis is required.

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.
