Overview
Other Diagnostic Studies
Diagnosis of cryptosporidiosis is made by microscopic identification of the oocysts in stool or tissue with acid-fast staining or direct immunofluorescence. Other diagnostic tests useful for the diagnosis of cryptosporidiosis include the following:
- Antigen-detection by enzyme-linked immunosorbent assay or immunochromatographic tests can be used for the diagnosis.
- Molecular methods such as polymerase chain reaction (PCR) are helpful in confirmation of the diagnosis and have high sensitivity.
- Cryptosporidial enteritis also can be diagnosed from small sections from intestinal biopsy.
