Specimen Type Describes the specimen type needed for testing

Plasma 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 sufficient blood in a lavender-top (EDTA) tube(s). Spin down and transfer to a plastic Amber vial (T192) to protect from light within 30 minutes of collection. Freeze and send 4 mL EDTA plasma frozen on dry ice.

Note: Collection date 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.
