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.

Draw blood in a plain, red-top tube(s).  Separate within 1 hour of collection, freeze immediately. Send 0.5 mL serum frozen.

Note:    1. Serum gel tube is okay, but must pour off into a plastic screw cap vial and freeze.

           2. Minimum volume does not permit for repeat analysis


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.

0.1 mL
NOTE: Minimum volume does not allow for repeat analysis.
