Microsporidia by PCR
Preferred test to diagnose Microsporidia in immunocompromised patients with persistent diarrhea if Encephalitozoon spp (E. intestinalis/E. hellem/E. cuniculi) or E. bieneusi is the suspected infectious agent.

A negative result does not rule out the presence of PCR inhibitors in the patient specimen or test-specific nucleic acid in concentrations below the level of detection by this test.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
This test detects and speciates Enterocytozoon bieneusi. The nucleic acid from Encephalitozoon intestinalis, Encephalitozoon hellem, and Encephalitozoon cuniculi will be detected by this test but cannot be differentiated.
