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), serum gel tube(s) is acceptable. Spin down and send 1 mL of serum frozen in a plastic vial.



Draw blood in a green-top (lithium heparin) tube(s), plasma gel tube(s) is acceptable.  Spin down and send 1 mL lithium heparin plasma frozen in a plastic vial.


Separate specimens must be submitted when multiple tests are ordered.

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




Cold reject; Warm reject
