Diagnosis of Cyclosporiasis
Stool tests To diagnose cyclosporiasis, a stool sample is examined under a microscope forCyclosporaeggs. Specialized techniques can be used to increase the chances of identifying the eggs. Molecular techniques are available in some reference laboratories to identify parasite DNA. When stool examination does not reveal a cause of persistent diarrhea, doctors may use a flexible viewing tube ( Endoscopy ) to examine the upper part of digestive tract and obtain a sample of tissue (a biopsy) to be examined under a microscope and analyzed for parasite DNA.
