Question: How to diagnose Parasites - Fascioliasis (Fasciola Infection) ?
Answer: The standard way to be sure a person is infected with Fasciola is by seeing the parasite. This is usually done by finding Fasciola eggs in stool (fecal) specimens examined under a microscope. More than one specimen may need to be examined to find the parasite. Sometimes eggs are found by examining duodenal contents or bile. Infected people don't start passing eggs until they have been infected for several months; people don't pass eggs during the acute phase of the infection. Therefore, early on, the infection has to be diagnosed in other ways than by examining stool. Even during the chronic phase of infection, it can be difficult to find eggs in stool specimens from people who have light infections. Certain types of blood tests can be helpful for diagnosing Fasciola infection, including routine blood work and tests that detect antibodies (an immune response) to the parasite.

Question: What are the treatments for Parasites - Fascioliasis (Fasciola Infection) ?
Answer: The first step is to make sure the diagnosis is correct. For more information, patients should consult their health care provider. Health care providers may consult with CDC staff about the diagnosis and treatment of fascioliasis. The drug of choice is triclabendazole. In the United States, this drug is available through CDC, under a special (investigational) protocol. The drug is given by mouth, usually in one or two doses. Most people respond well to the treatment. More on: Resources for Health Professionals: Treatment
