Fecal Giardia lamblia Antigen ELISA Kit


This ELISA (enzyme-linked immunosorbent assay) kit is intended for the qualitative detection of Giardia lamblia antigen in stool samples. The assay is a useful tool in the diagnosis of active Giardia lamblia infections in acute or chronic gastroenteritis.

Giardiasis is a diarrheal illness caused by Giardia lamblia after ingestion of Giardia cysts. Once a person has been infected by Giardia, the parasite lives in the intestine and is passed in stool; one bowl movement can release millions of these parasites. Giardia is found in soil, food, water, or surfaces that have been contaminated with the feces from infected humans or animals. Because the parasite is protected by an outer shell, it can survive outside the bodiardiay for long periods of time.

Giardia lamblia has become one of the most widespread causes of chronic diarrhea globally. An infection can cause a variety of intestinal symptoms, either acute or chronic, which include diarrhea, gas or flatulence, greasy stools that tend to float, stomach cramps, upset stomach, and nausea. Some people with giardiasis have no symptoms at all. Giardia cysts are still shed in these asymptomatic cases.

The method used for the diagnosis of giardiasis in the past has been the detection of Giardia cysts in stool by microscopy. Tecently, specific Giardia antigen ELISA greatly simplified the diagnostic procedure and is as sensitive as the microscopic method. Another advantage of using Giardia antigen ELISA is that it does not require the intact organisms in the test specimen.
