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 only 1 of the following specimens:



Draw blood in a plain, red-top tube(s). Spin down and transfer 0.7 mL serum to a screw-top plastic vial. Submit frozen.

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



Draw blood in a yellow-top (ACD) or lavender-top (EDTA) tube(s). Spin down and transfer 0.7 mL ACD or EDTA plasma to a screw-cap plastic vial. Submit frozen.

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.

0.3 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

Specimens other than

Serum, plasma

Anticoagulants other than





Warm OK 48 hrs; Cold OK





Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
