Diagnostic Considerations

Many laboratories do not routinely test for Cryptosporidium, and in many cases the tests used for the organism are insensitive. [1] However, failure to consider Cryptosporidium as the cause of diarrhea, particularly in cases with prolonged symptoms, may cause expensive diagnostic tests and consultations to be undertaken.

Rotavirus enteritis is one disorder to consider in the differential diagnosis of cryptosporidiosis. Other infections to consider include the following:

  • Giardia lamblia

  • Microsporidia

  • Cyclospora cayetanensis

  • Clostridium difficile
