SCREEN VERIFICATION TEST H. Pylori antigen Description In vitro diagnostic medical device CE 0123. Rapid test for the qualitative detection of Helicobacter pylori (H. pylori) antigens in human feces. For in vitro self-diagnostic use only. Precautions 1. For in vitro self-diagnostic use only. 2. Do not eat, drink, or smoke in the sample or kit handling area. 3. Store in a dry place between 2-30°C (36-86°F), avoiding areas with excessive humidity. If the sealed pouch is damaged or opened, do not use the test. 4. Use a clean container to collect the stool sample. 5. Carefully follow the indicated times. 6. Use the test only once. 7. Do not disassemble or touch the test window on the stand. 8. The kit should not be frozen or used after the expiration date printed on the package. 9. After use, all components should be disposed of in household waste. 10. Keep out of reach of children. How to use 1. Wash your hands with soap and rinse with clean water. 2. For fecal sample collection: The fecal sample should be collected on the stool collection sheet or in a clean container. Please use the stool collection sheet, avoiding contamination of the sample by taking appropriate precautions to ensure that the sample or the part of the paper containing the sample does not come into contact with other contaminants, including bathroom products. 3. To analyze stool samples: Unscrew the cap of the sample collection tube, then randomly insert the collected sample with the applicator into the stool sample at least 3 different places. Do not shake the stool sample. Replace and secure the cap on the collection tube, then shake the sample collection tube vigorously to mix the sample and extraction buffer. 4. Allow the package to reach room temperature before opening. Remove the test device from the sealed package and use it as soon as possible. Best results are obtained if the test is performed immediately after opening the package. 5. Open the cap of the sample collection tube and break off the tip. Invert the tube and place 2 full drops of the extracted sample into the sample well (S) on the test device, then start the timer. Avoid trapping air bubbles in the sample well (S). 6. Read results after 10 minutes. Do not read results after 20 minutes. Reading the results POSITIVE*: Two lines appear. Both the T (Test) line and the C (Control) line appear. This result indicates the presence of H. pylori antigen in the stool and you should consult a doctor. NEGATIVE: A colored line appears in the control region (C). No line appears in the test region (T). This result indicates that the presence of H. pylori antigen could not be detected in the stool. NULL: Control line does not appear. The most likely reasons for the control line not appearing are insufficient sample volume or improper procedural techniques. Review the procedure and repeat the test with a new kit. If the problem persists, discontinue use of the kit immediately and contact your local distributor. The intensity of the color in the test region (T) varies depending on the concentration of H. pylori antigen present in the sample. Therefore, any shade of color in the test line (T) is considered positive. limitation 1. The H. pylori Antigen (Fecal) Test is for in vitro diagnostic use only. The test is to be used only for the detection of H. pylori antigens in stool specimens. This qualitative test does not allow for the determination of the quantitative value or rate of increase in the concentration of H. pylori antigen. 2. The H. pylori antigen (fecal) test will only indicate the presence of H. pylori in the sample and should not be used as the sole criterion for establishing H. pylori as the causative agent of peptic or duodenal ulcers. 3. As with all diagnostic tests, all results must be interpreted in conjunction with other clinical information available to the physician. 4. If the test result is negative and clinical symptoms persist, further testing using other clinical methods is recommended. A negative result does not in any way exclude the possibility of H. pylori infection. 5. In the case of some antibiotic treatments, the concentration of H. pylori antigens may fall below the minimum detectable level of the test. Therefore, diagnosis during antibiotic treatment should be made with caution. Conservation The kit can be stored at room temperature or in a refrigerator (2-30°C). The test is stable until the expiration date printed on the sealed package. The test should remain in the sealed pouch until use. DO NOT FREEZE. Do not use after the expiration date.
