Stewardship guidance for PNA-FISH reporting^a

PNA-FISH result	Reported organism	Comment
C. albicans/parapsilosis	C. albicans/parapsilosis	Unable to differentiate between C. albicans and C. parapsilosis. Both organisms are typically susceptible to fluconazole. Culture identification to follow.b
C. glabrata/krusei	C. glabrata/ krusei	Unable to differentiate between C. glabrata and C. krusei. Culture identification to follow. Use Micafungin until final susceptibilities are available.c
C. tropicalis	C. tropicalis	Typically susceptible to fluconazole.
Not-detect	The Yeast seen on Gram stain will be identified by routine culture. The yeast could not be identified by the PNA FISH.b
PNA-FISH culture discordant result	Corrected report	This isolate was originally Not Detected by the PNA FISH.

^aThe stewardship guidance is based on institutional practice and guidelines and may not be generalizable.

^bRemove comment when culture results are updated.

^cRemove comment when sensitivity results are updated. C. krusei is intrinsically resistant to fluconazole.

PNA indicates peptide nucleic acid; FISH, fluorescence in situ hybridization.
