Specimen Requirements

Specimen

Isolated acid-fast bacillus (AFB) on agar or egg-based media; broth system positive for AFB (ensure it is not contaminated with non acid-fast bacteria)

Volume

Entire container

Container

Screw cap agar-slant tube; bacterial swab transport inoculated with isolated colonies from a pure culture; liquid-based broth tube from BD, bioMrieux or Versatrek (Slant, swab or liquid-based broth must be packed as an etiologic agent)

Storage Instructions

Maintain specimen at room temperature.

Causes for Rejection

Specimen received leaking or in broken transport tube or vial; unlabeled or name discrepancy between specimen and request label; primary clinical specimen received

Test Details

Use

This test is used to identify acid-fast bacteria referred from another laboratory that has performed the culture of the clinical sample. Note: PCR testing for identification of M. avium complex and M. tuberculosis complex will be performed on liquid-based broth submissions only. Organisms not identified by PCR will have additional charges for identification by MALDI-TOF and/or nucleic acid sequencing.
