Test ID: SSF1 Nocardia Stain, Varies

Reporting Name

Nocardia Stain

Useful For

Detection of Nocardia species and other partially-acid fast aerobic actinomycetes in clinical specimens

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.
