[1] [2] [3] The parasite attaches to the intestinal epithelium by a ventral disc (syn.
According to the CDC, the detection of antigens on the surface of organisms in stool specimens is the current test of choice for diagnosis of giardiasis and provides increased sensitivity over more common microscopy techniques. [34] A trichrome stain of preserved stool is another method used to detect Giardia. [35]
