How is microsporidiosis diagnosed?

There are several tests available to diagnose microsporidia infection. Microscopic examination of stained samples of body fluids, primarily fecal samples, allows for rapid diagnosis, although the exact species of microsporidia may not be identified. Urine samples can also be used to detect spores when the kidney and/or bladder are involved.

A powerful microscope, called a transmission electron microscope, is needed to identify the species of microsporidia. However, this form of testing is expensive, and it is not available for routine use in all laboratories.

Other methods, such as immunofluorescence assays and polymerase chain reaction (PCR) testing, can also identify microsporidia infection in the research-laboratory setting.

Finally, blood tests and imaging studies can also assist in detecting microsporidiosis.
