Specimen Type 
Describes the specimen type needed for testing
Varies
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:
Serum
Draw blood in a plain, red-top tube(s). (Serum gel tube is not
acceptable.) Spin down and send 3 mL of serum refrigerate in
plastic vial. Trough levels are most reproducible.
Plasma
Draw blood in a green-top (Sodium or Lithium) tube(s). (Plasma gel
tube is not acceptable.) Spin down and send 3 mL of heparinized
plasma refrigerate in plastic vial. Trough levels are most reproducible.
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.
0.6 mL
Note: Submission of the minimum volume results in an elevated
reporting limit and inability to repeat analysis.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
