Test Catalog

Test ID: VIBC    
Vibrio Culture, Feces

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, the reflex tests may be performed and charged separately.

Specimen Type Describes the specimen type validated for testing


Additional Testing Requirements

1. If susceptibility testing is desired, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, MIC, Varies. If susceptibility testing is not needed (eg, due to lack of recovery of Vibrio species from feces), ZMMLS will not be performed and the order will be canceled.

2. In some cases, local public health requirements may impact Mayo Clinic Laboratories (MCL) clients, requiring submission of isolates to public health laboratories. Clients should familiarize themselves with local requirements and are responsible for submitting isolates to appropriate public health laboratories. Clients can obtain isolates of Vibrio species recovered from specimens submitted to MCL by calling 800-533-1710 as soon as possible after reporting to ensure viability of the bacterium.
