How is blastocystosis diagnosed?

If you have gastrointestinal symptoms, your healthcare provider will:

• Discuss your medical history, including your travel history and contact with animals.
• Perform a physical exam.
• Collect a stool sample for identification of Blastocystis under a microscope.

Other tests can help detect Blastocystis and its subtypes but are usually only available in research settings. Even if you have blastocystosis, your provider will also look for other organisms that may be causing your symptoms.
