Modified ZN Stool Stain - Parasitology Applications

Low-acid carbol fuchsin formulation preserves acid-fast oocysts across diarrheal disease diagnosis in immunocompromised patients.

Parasitology laboratories detect 1% H2SO4-resistant oocysts confirming cryptosporidiosis. Red oocyst preservation differentiates from yeasts preventing false negatives.

Quality control confirms 1% acid stability, oocyst retention, and fecal debris contrast. Stool-specific modification prevents tissue digestion.
