Giardia Antigen, Stool **

 
 
Clinical Information:
Giardia duodenalis (also known as G lamblia, G intestinalis) is a flagellated protozoan parasite found in contaminated natural streams, lakes, and surface water municipal reservoirs. Humans become infected when ingesting the environmentally resistant cysts in water, food, and by the fecal-oral route.
 
Reference Value:

Negative

 
Interpretation:
A positive enzyme-linked immunosorbent assay (ELISA) indicates the presence in a fecal specimen of Giardia antigens.
As per the manufacturer, the assay has a sensitivity of 96%, specificity of 97%, and a positive predictive value of 95%.
Interpretation of results should be correlated with patient symptoms and clinical picture.
Feces containing large amounts of leukocytes or red blood cells may give falsely positive results.
