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 2 tubes of blood, 10 mL each in special Streck Black/Tan top tube kit (MML supply number T715). Ship ambient.

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.

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




Warm reject; Cold reject
