HelpTest ID LCMSP Microsporidia species, Molecular Detection, PCR, Varies
Useful For
Detection of Enterocytozoon bieneusi and Encephalitozoon species in fecal and urine specimens to support the clinical diagnosis of microsporidiosis
Highlights
This test is intended to be used for immunocompromised patients with persistent, watery diarrhea. See the Parasitic Investigation of Stool Specimens Algorithm.
This test is intended to be used for the detection of Enterocytozoon bieneusi and Encephalitozoon species DNA in fecal and urine specimens to support the clinical diagnosis of microsporidiosis. Other sources should be tested using MTBS / Microsporidia Stain, Varies.
A negative result indicates the absence of detectable DNA from Enterocytozoon bieneusi and Encephalitozoon species in the specimen, but does not rule out ongoing microsporidiosis. See Interpretation for more information.

VariesAdvisory Information
For specimens other than feces or urine, MTBS / Microsporidia Stain, Varies should be ordered since it will detect other microsporidia that are not targeted by this assay.
Necessary Information
Specimen source is required.
