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.

Container/Tube: Amniotic fluid container

Specimen Volume: 10 mL

Collection Instructions:

1. Centrifuge at 1,000 rpm or 200 x G for 10 minutes, separate supernatant, and send both supernatant and sediment in separate plastic vials.

2. Label specimens sediment and supernatant.

Additional Information: Include estimate of duration of pregnancy (in weeks).

Forms:

1.     1. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.

2.     2. If not ordering electronically, submit a Biochemical Genetics Request Form (Supply T439) with the specimen.

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.
