In the realm of medical diagnostics, rapid and accurate testing is a cornerstone of effective treatment and control of infectious diseases. Amongst these, typhoid fever remains a significant global health challenge, necessitating tools that offer not only precise but also swift results. QL Biotech is proud to introduce an innovative solution in this domain - the Typhoid Ag Rapid Test Device, an essential addition to our product line that epitomizes the fusion of convenience with reliability. Our state-of-the-art Typhoid Ag Rapid Test Device is specifically designed to meet the exigent requirements of fast-paced clinical settings. Utilizing a lateral flow chromatographic immunoassay method, this device is engineered for the qualitative detection of typhoid antigens in feces - a critical advancement in the field of infectious disease diagnostics. The principle behind this transformative diagnostic tool hinges on the rapid identification of the presence of typhoid antigens, facilitating the swift initiation of appropriate medical interventions.

• ASSAY PROCEDURE

  • 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 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. 
    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.

  
  

  INTERPRETATION OF ASSAY RESULT

  

• NOTE:

  • 1.The intensity of the color in test region (T) may vary depending on the concentration of aimed substances present in the specimen. Therefore, any shade of color in the test region should be considered positive. Besides, the substances level cannot be determined by this qualitative test.
  • 2.Insufficient specimen volume, incorrect operation procedure, or performing expired tests are the most likely reasons for control band failure.
