Test Description

PAS-Green Stain Kit is used to identify fungi in tissue sections on the Artisan™ Link and Artisan™ Link Pro Staining Systems. The most commonly used application is for demonstrating fungi in skin infections. Unlike GMS, the PAS-Green technique will not stain all fungi and yeast. However, fungi typically found in dermatologic specimens are commonly identified using PAS-Green. Positive fungi: magenta and the remaining tissue elements: blue/green.
