TEST PRINCIPLE
PocTell® H pylori ag Rapid Test Device (Feces) is a non-invasive lateral flow assay, rapid, precise and easy to perform.This test makes use of specific antibodies against H. Pylori antigen adsorbed onto a reactive membrane. If H. Pylori is present in stool specimen, the specific antigen is bound by the second antibody which is conjugated with colloidal gold particles. A generic antibody, fixed onto the reactive membrane, in shape of the band, is able to capture the second conjugated antibody, assuring the correctness of the test performance.
DIRECTIONS FOR USE
Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.
1.Specimen collection and pre-treatment:
1)Unscrew and remove the dilution tube applicator. Be careful not to spill or spatter solution from the tube. Collect specimens by inserting the applicator stick into at least 3 different sites of the feces.
2)Place the applicator back into the tube and screw the cap tightly. Be careful not to break the tip of the dilution tube.
3)Shake the specimen collection tube vigorously to mix the specimen and the extraction buffer. Specimens prepared in the specimen collection tube may be stored for 6 months at -20°C if not tested within 1 hour after preparation.
2.Testing
1)Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. To obtain a best result, the assay should be performed within one hour.
2)Using a piece of tissue paper, remove the tip of the dilution tube. Hold the tube vertically and dispense 2-3 drops of solution (approximately 80-120 μl) onto the sample pad of the Test Device.
Avoid trapping air bubbles onto the sample pad, and do not drop any solution in observation window.
As the test begins to work, you will see color move across the membrane.
3.Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
