Nocardia Stain, Varies
Use
Detecting Nocardia species and other partially-acid fast aerobic actinomycetes in clinical specimens is crucial for diagnosing infections, especially in immunocompromised patients. These infections can result in serious conditions such as pneumonia, skin abscesses, bacteremia, brain abscesses, eye infections, and joint infections. The modified acid-fast stain allows for direct detection of these species in clinical specimens.
Special Instructions
When ordering this test, ensure that the specimen source is appropriately documented. If not ordered electronically, complete the Microbiology Test Request form (T244) and send it with the specimen. Tissue processing may be performed for an additional charge based on the results and interpretations of the initial tests.
Limitations
Artifacts may exhibit nonspecific staining and could be confused with organisms. Not all aerobic actinomycetes are partially acid-fast, and a negative stain result does not exclude infection. Culture should be performed to improve detection accuracy. Nocardia and other aerobic actinomycetes can grow well on mycobacterial culture media, so cultures like CTB/Mycobacteria and Nocardia Culture are recommended.
