The innovative HAV IgG/IgM Test Cassette from QL Biotech forms the most reliable solution for rapid tuberculosis (TB) antigen detection. This scientifically advanced device operates based on the lateral flow chromatographic immunoassay concept, further enhanced by the double antigen-sandwich technique principle. As a cutting-edge technological tool, our HAV IgG/IgM Test Cassette provides quick and precise results, offering an essential aid in the timely diagnosis and subsequent treatment of tuberculosis. This test cassette has been specifically designed to ensure the utmost accuracy in the detection of the TB antibody, thereby contributing to improved patient outcomes. Underpinned by the double-antigen sandwich technique, our HAV IgG/IgM Test Cassette leverages two primary components - the pre-coated gold conjugate pad containing recombinant TB antigens conjugated with colloid gold (TB conjugates) and nitrocellulose membrane coated with a TB antigen. This protocol ensures high sensitivity and specificity for TB antibody detection. Upon adding the specimen to the sample well, the TB antigens bind with any present TB antibodies forming TB antibody-antigen complexes. As the specimen migrates along the membrane by capillary action, these complexes are captured by the TB antigens coated on the membrane, thereby forming a colored test line in the device, an indication of a positive result.

• ASSAY PROCEDURE

  • 1. Bring the specimen and test components to room temperature. Place the test device  on a clean, flat surface. 
    2. Be sure to label the device with specimen’s ID number. 
    3. Fill the plastic dropper with the specimen. Holding the dropper vertically, dispense 2  drops (about 80 µL) of specimen into the sample well making sure that there are no  air bubbles. Then add 1 drop of buffer into the sample well. Set up timer. 
    4. Results can be read in 10 minutes. Positive results can be visible in as short as 1  minute. Don’t read result after 10 minutes. To avoid confusion, discard the test  device after interpreting the result.

  
  

  INTERPRETATION OF RESULTS

  
  

  •  

In the absence of TB antibodies in the specimen, there will not be a color change, indicating a negative result. This intuitive, color-based result presentation makes the HAV IgG/IgM Test Cassette easy-to-use and extraordinarily helpful in prompt TB detection. In summary, QL Biotech's HAV IgG/IgM Test Cassette offers a revolution in the speed and accuracy of TB antibody detection. Its state-of-the-art technology ensures reliability, giving healthcare professionals a tool they can trust in the fight against tuberculosis.
