Specimen:
Sputum
Collection Medium:
Sterile container
Minimum:
3 mL of sputum
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.
Specimen Instructions:
Send specimen in a screw-capped, sterile container. Maintain sterility and forward promptly to laboratory.
Analytic Time:
Upon report.
Reference Range:
Negative
Interpretive Data:
A positive result indicates the presence of Mycobacterium tuberculosis complex DNA. Members of the Mycobacterium tuberculosis complex detected by this assay include Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium bovis BCG, Mycobacterium africanum, Mycobacterium canetti, and Mycobacterium microti. The other species within the Mycobacterium tuberculosis complex (Mycobacterium bovis subspecies caprae and Mycobacterium pinnepedi) should, in theory, be detected using the primer and probe sequences in this assay, but they have not been tested at this time. This assay method does not distinguish between the species of the Mycobacterium tuberculosis complex.
Comments:
It is highly recommended that this test only be ordered after consultation with Infectious Disease or the Microbiology Laboratory pathology resident. This is not a front-line screening test for tuberculosis and has limited negative predictive value.
Methodology:
Polymerase Chain Reaction (PCR)
