Collection:
Remove any creams, lotions, deodorants, talcum, etc. prior to the collection of scrapings as these materials may interfere with this test. Incise vesicle around periphery with a sterile scalpel. Lift back the top of the lesion and remove excess fluid by gently blotting with a sterile swab. This swab can be placed in UTM and transported on ice for culture. Scrape the base of the lesion with a sterile scalpel blade and spread the collected cells thinly within the circles of 2 microscope slides. Allow slides to air dry.
Comments:
The FA stain is more sensitive than VZV culture if adequate cellular material is collected.
