HelpTest 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 MTBXS / Mycobacterium tuberculosis Complex, Molecular Detection and Rifampin Resistance, PCR, Sputum.
Shipping Instructions
