Z-N Carbol Fuchsin TB Stain - Mycobacteriology

Certified ZN kit (carbol fuchsin, acid-alcohol, methylene blue) confirms AFB positivity across sputum cytology and tissue biopsy workflows.

Microbiology laboratories quantify bacillary load (1+ to 4+) guiding anti-TB therapy. Red rod preservation withstands 3% acid-alcohol decolorization confirming mycobacterial identity.

Quality control verifies carbol fuchsin penetration, acid-fast retention, and counterstain contrast. Complete kit prevents component mismatch errors.
