Method Name
Modified Acid-Fast Stain
Forms
If not ordering electronically, complete, print, and send a Microbiology Test Request (T244) with the specimen.
Useful For
Detecting Nocardia species and other partially-acid fast aerobic actinomycetes in clinical specimens
Specimen Minimum Volume

Clinical Information
Nocardia species and other aerobic actinomycetes can cause significant disease in immunocompromised patients. Clinical presentations can include, but are not limited to, pneumonia, skin abscess, bacteremia, brain abscess, eye infection, and joint infection.
The modified acid-fast stain can detect Nocardia species and other partially-acid fast aerobic actinomycetes directly from clinical specimens.
Interpretation
Patients whose specimens are reported as partially acid-fast positive should be considered potentially infected with Nocardia species or other aerobic actinomycetes, pending definitive diagnosis by molecular methods or culture.
