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.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space.
