AFB Identification : 0060999

Mnemonic: MC AFBID

Methodology: Standard reference procedures for identification of AFB. DNA probes available for M. tuberculosis complex and M. avium-intracellulare complex. DNA sequencing and other molecular techniques are used for other mycobacteria species.
Performed: Sun-Sat
Reported: Varies (depends on organism growth)
Specimen Required: Collect: Actively growing organism, in pure culture.

Specimen Preparation: Transfer viable organism to sealed container.

Storage/Transport Temperature: Room temperature.

Submit specimen according to Infectious Substance, Category A, shipping guidelines.


Remarks: Indicate source of organism and any other pertinent information: growth rate of the organism, DNA probe results.
Probes can be performed directly from Middlebrook 7H9 broth. MGIT is not suitable for direct probe testing.


Unacceptable Conditions: Mixed cultures or non-viable organisms. Organisms submitted on an agar plate.

Stability (collection to initiation of testing): Ambient: 2 weeks; Refrigerated: 2 weeks; Frozen: 2 weeks
Reference Interval:
Complete identification of clinically significant isolates.
Interpretive Data: For identification by DNA sequencing:

Refer to Statement B under Testing Information at http://www.aruplab.com.
Note: A handling fee will be billed for all organisms submitted that are not in pure culture as requested in the specimen requirements.
Identification of AFB isolates is billed by individual probes and tests performed.
CPT Code(s): CPT codes for identification vary based on method.
Cross References: Identification, Mycobacteria (AFB Identification), Organism Identification, AFB (AFB Identification)
