Giardia Ag Rapid Test (RAP-5407 and RAP-5408) chromatographic immunoassay is a procedure for in vitro qualitative detection of Giardia antigens in stool samples. Giardia intestinalis, also called Giardia lamblia, is a gastrointestinal protozoan parasite infecting various species (mammals, birds, etc.). It causes a clinical picture that ranges from the symptom-free carrier to cases of acute or chronic diarrheic disease, especia…
