Samonella Paratyphi Ag

The Salmonella paratyphi Antigen Rapid Test Cassette (Feces) is a qualitative, lateral flow
immunoassay for the detection of S. paratyphi antigen in human feces. In this test, the
membrane is pre-coated with anti-S. paratyphi antibodies on the test line region of the test.
During testing, the specimen reacts with the particle coated with anti-S. paratyphi antibodies.
The mixture migrates upward on the membrane by capillary action to react with anti-S. paratyphi
antibodies on the membrane and generate a colored line. The presence of this colored line in the
test region indicates a positive result, while its absence indicates a negative result. To serve as a
procedural control, a colored line will always appear in the control line region indicating that
proper volume of specimen has been added and membrane wicking has occurred.
