H.Pylori AntigenInfectious Disease Blood Tests , Feces Specimen Blood Test Kit One Step H.Pylori Antigen Rapid Test , to detec Helicobacter Pylori Antigen,Feces specimen,gold colloidal method

 

Product Name:


One Step H.Pylori Antigen Rapid Test (Cassette)

One Step Helicobacter Pylori Antigen Rapid Diagnostic test

 

 

Intended Use:

 

The H. Pylori Ag Rapid Test Device (Feces) is a rapid chromatographic immunoassay for the qualitative detection of antigens to H. Pylori in feces to aid in the diagnosis of H. Pylori infection.

 

 

Test Principle:

 

 

The 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.

 

 

TEST PROCEDURE

 

Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.

 

Specimen collection and pre-treatment:

 

Use the specimen collection container for specimen collection. Best results will be obtained if the assay is performed within 6 hours after collection.

 

For solid specimens: 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 to collect approximately 50 mg of feces (equivalent to 1/4 of a pea).

 

For liquid specimens: Hold the pipette vertically, aspirate fecal specimens, and then transfer 2 drops (approximately 50 µL) into the specimen collection tube containing the extraction buffer.

Place the applicator back into the tube and screw the cap tightly. Be careful not to break the tip of the dilution tube.

 

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.

 

 

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.

Using a piece of tissue paper, break the tip of the dilution tube. Hold the tube vertically and dispense 3 drops of solution into the specimen well (S) of the test device.

 

Avoid trapping air bubbles in the specimen well (S), and do not drop any solution in observation window.

 

As the test begins to work, you will see color move across the membrane.Wait for the colored band to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.

 

Note: If the specimen does not migrate (presence of particles), centrifuge the extracted specimens contained in the extraction buffer vial. Collect 80 µL of supernatant, dispense into the specimen well (S) of a new test device and start afresh following the instructions mentioned above.

 

INTERPRETATION OF RESULTS

 

POSITIVE:* Two lines appear. One colored line should be in the control line region (C) and another apparent colored line should be in the test line region (T).

 

*NOTE: The intensity of the color in the test line region (T) will vary depending on the concentration of TP antibodies present in the specimen. Therefore, any shade of color in the test line region (T) should be considered positive.

 

NEGATIVE: One colored line appears in the control line region (C). No line appears in the test line region (T).

 

INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
