Test ID TBSP Mycobacterium tuberculosis Complex Species Identification, PCR, Varies

Infectious


Ordering Guidance


This test should be used to identify the species within the Mycobacterium tuberculosis complex from a known M tuberculosis complex isolate.

 

For identification of M tuberculosis complex from isolate growth, order CTBID / Culture Referred for Identification, Mycobacterium and Nocardia, Varies.

 

For rapid identification of M tuberculosis complex directly from a specimen, order MTBRP / Mycobacterium tuberculosis Complex, Molecular Detection, PCR, Varies or MTBXP / Mycobacterium tuberculosis Complex, Molecular Detection, PCR, Sputum.



Shipping Instructions


1. See Infectious Specimen Shipping Guidelines in Special Instructions.

2. Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance.
