Necessary Information

Specimen source is required.

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.

The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by Vancomycin-Resistant Enterococcus DNA is unlikely.
