Specimen Type Describes the specimen type needed for testing


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.

Submit one of the following:



Draw blood in a plain, red-top tube(s). (Serum gel tube is acceptable.) Spin down within 2 hours of collection, pour off and send 1 mL of serum frozen in a plastic vial.



Draw blood in a lavender top (EDTA) or pink top (K2EDTA) tube. Spin down within 2 hours of collection, pour off and send 1 mL EDTA plasma frozen in a plastic vial.


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.
