Acid-fast Organism Identification by PCR, MALDI-TOF and/or Sequencing

Test Number 183158

Test number copied

CPT 87150

Synonyms

AFB Culture, Identification

Test Details

Methodology

Identification by PCR, MALDI-TOF and/or nucleic acid sequencing

Result Turnaround Time

15 - 24 days

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

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 VersaTREK liquid-based broth submissions only. Organisms not identified by PCR will have additional charges for identification by MALDI-TOF and/or nucleic acid sequencing.

Special Instructions

If reflex test is performed, additional charges/CPT code(s) may apply.

Limitations

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.

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, bioMerieux 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
