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

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.
Necessary Information
Specimen source and suspected organism identification are required.
Specimen Required
Supplies: Infectious Container, Large (T146)
Specimen Type: Mycobacterium tuberculosis complex isolate growing in pure culture
Container/Tube: Growth on solid slant media eg, Middlebrook 7H10, 7H11 and Lowenstein Jensen.; growth in broth medium eg, Mycobacteria Growth Indicator Tube, 7H9 broth BACT/ALERT MP or VersaTREK. Turnaround time for results may be delayed, if subculture to Middlebrook agar medium is needed to ensure purity.
Specimen Volume: Isolate with visible growth on solid media; if broth is sent, ≥3 mL of broth culture
Collection Instructions:
1. Organism must be in pure culture, actively growing. Do not submit mixed cultures.
2. Place specimen in a large infectious container and label as an etiologic agent/infectious substance.
