We are experiencing transient false positive ZN staining on skin biopies. Today a slide had clumped AFB over the majority of the slide where no tissue was present. Previous to this, only one or two bacilli were noted on the slide.
Has anyone investigated and found a contaminated waterbath or perhaps the Kinyoun's is the culprit as our lab reuses both? Any help would be appreciated.
