Method

Polymerase Chain Reaction -

PCR for Mycobacterium tuberculosis is done by GeneXpert on request.

Sputum - will be decontaminated before PCR testing.
Pleural fluid - >5mLs undiluted or in EDTA tube.
Blood or bone marrow - Collect into EDTA tube.
FNA or tissue biopsy - Collect into sterile container.
CSF - Minimum 1.0 mL but preferably 5.0 mLs or more (consultation with Microbiologist desirable).

Seegene AnyPlex testing available for non-tuberculous mycobacteria after consultation with Microbiologist.

Additional Information

GeneXpert allows for detection  of M.tuberculosis and determination of Rifampicin susceptibility from direct specimens within 24 - 48 hours of receipt in the laboratory. For M.tuberculosis on ZN positive respiratory specimens sensitivity and specificity is close to 100%.  There is decreased sensitivity for ZN negative respiratory specimens and non-respiratory specimens.

Seegene AnyPlex allows for detection of MTB or other (non-speciated) mycobacteria.

Susceptibility testing, both genotypic and phenotypic, are completed when a M. tuberculosis culture has grown. First line susceptibilities include Rifampacin, Isoniazid, Ethambutol, Streptomycin and Pyrazinamde. For second Line susceptibilities please phone Microbiologist.
