Test Name: PAS-LG
Methodology: Special Stains
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.
A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen type or one (1) unbaked, unstained slide cut at 4-5 microns for H&E staining (required) and two to three (2-3) positively charged unstained slides cut at 3-4 microns for each test/antibody ordered.
Storage and Transport
Use cold pack during transport of paraffin blocks and unstained slides. Cold pack should not be placed in direct contact with the specimen during shipping
