Giardia Lamblia Ag

Giardia Lamblia Rapid Test Cassette (Feces) is based on the use of a membrane
technology with colloidal gold. A nitrocellulose membrane is sensitized with antibody
directed against Giardia Lamblia. The test’s specificity is ensured by an antibody specific to
a Giardia Lamblia antigen that is conjugated to the colloidal gold. This conjugate is dried on
a membrane.
The fecal sample must be diluted into the extraction buffer that is supplied with the test.
When extracted specimen come into contact with the strip, the conjugate migrates with the
sample by passive diffusion and the conjugate and sample material come into contact with
the anti-Giardia antibody in the T line. If the sample contains the G. lamblia antigen, the
conjugate-antigen complex will remain bound to the anti-Giardia reagent and a red line will
develop. Solution continues to migrate to encounter a second reagent that binds the
migration control conjugate, thereby producing a red control line that confirms that the test
is working properly. The result is visible within 10 minutes
