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. Serum should be separated from cells within 1 hour from time of collection or kept on ice prior to separation.
Spin down and send 1 mL of serum frozen in a plastic vial.
Draw blood in a heparin (green-top) tube(s). Plasma should be separated from cells within 1 hour from time of collection or kept on ice prior to separation. Spin down and send 1 mL of 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.
