Giardia Antigen, EIA, Stool details

Giardiasis is recognized as an important human intestinal disease in most areas of the world. The causative organism, Giardia duodenalis (lamblia), is the most frequently identified protozoan parasite in stool specimens submitted to public health laboratories. This parasite has been implicated in a number of epidemics, and the endemicity in the U.S. is well recognized. Acute symptoms of Giardiasis may include diarrhea, malabsorption, abdominal cramps, anorexia, nausea, weight loss, flatulence, anemia, and general weakness lasting from several weeks to several months. Chronic infections can also occur with or without an acute phase, are often associated with treatment failure, and may result in recurrent symptoms. Infection with Giardia may also be asymptomatic.
