What is the test? Cyclospora by smear examination is a microscopic stool test used to detect Cyclospora cayetanensis, a parasite that can cause intestinal infection. The examination typically uses a specially stained stool smear to identify characteristic round, acid-fast oocysts.
Why is it done?
Persistent or recurrent watery diarrhea
Abdominal cramps and bloating
Nausea or loss of appetite
Unexplained weight loss
Suspected parasitic intestinal infection
Travel- or food-associated diarrheal illness
Sample Required:
Fresh stool sample
Properly collected in a clean, sterile container
Method: Microscopic examination of a prepared stool smear using appropriate staining techniques, commonly modified acid-fast staining, for detection of Cyclospora oocysts.
Result:
Positive: Cyclospora oocysts detected
Negative: No Cyclospora oocysts detected in the examined specimen
Important Note: Cyclospora may be shed intermittently. Therefore, a single negative result does not always exclude infection, and repeat stool examination may be recommended when clinical suspicion remains high.
Clinical Significance: A positive result supports the diagnosis of Cyclospora infection (cyclosporiasis) and should be interpreted along with the patient's symptoms and clinical history.
