Modified Acid Fast Stain Nocardia/Actinomycetes
Also known as: Partial Acid Fast Stain
Use
Used to detect partial acid-fast organisms such as Nocardia spp. and aerobic actinomycetes in various clinical specimens. This microscopic stain provides presumptive identification of these organisms, which have characteristic partial acid-fast appearance and may require further confirmatory testing.
Special Instructions
Not provided.
Limitations
As a presumptive stain, it does not provide definitive identification to species level and may require follow-up culture or molecular testing for confirmation. Interpretation is dependent on sample quality and adequate organism load; false negatives may occur in paucibacillary specimens.
