Mycobacteria and Nocardia Culture, Varies
Use
This test is used for the detection and identification of Mycobacterium species, Nocardia species, and other aerobic actinomycetes. It is clinically significant for diagnosing infections caused by these organisms, which can lead to significant morbidity and mortality in both immunocompromised and immunocompetent hosts. Identification of these organisms to the species level is essential for guiding appropriate therapy, and culturing is necessary for antimicrobial susceptibility testing.
Special Instructions
Not provided.
Limitations
The recovery of mycobacteria depends on the number of organisms present in the specimen, the collection methods, and the processing methods. The use of BBL MGIT PANTA antibiotic mixture, essential for nonsterile specimens, may inhibit some mycobacteria. There is also a low yield from swab specimens, and appropriate specimen collection and handling are essential for accurate results. Certain specimen types and conditions could cause specimen rejection, like blood, serum, or fixed tissue.
