Rapid Detection with HCV Cassette: Strep A Test Device
In the ever-evolving landscape of biotech innovation, QL Biotech stands at the forefront, particularly with our flagship product - the Strep A Rapid Test Device/Strip. Enhanced for swift and reliable detection, this product embodies a significant leap in diagnostic methodologies, especially when integrated with the precision of HCV Cassette technology. The essence of our product is not just in its functionality but in its promise to deliver results that healthcare professionals can trust.
The core technology of the Strep A Rapid Test lies in its sophisticated lateral flow immunoassay mechanism. Designed to qualitatively detect the presence of Strep A carbohydrate antigen from a simple throat swab, the test strip showcases the remarkable fusion of speed and accuracy. The intersection of biotechnology with user-friendly design principles ensures that the product is accessible not only to healthcare professionals but also to institutions aiming for high standards in health diagnostics. The inclusion of HCV Cassette further accentuates the product's reliability, providing a clear, concise reading that underscores our commitment to precision in medical diagnostics. Expanding upon the foundation laid by traditional methods, our Strep A Rapid Test Device innovates at every level. Its application extends beyond the mere identification of the Strep A antigen; it paves the way for a quicker diagnostic process, allowing for timely intervention and treatment. The significance of integrating HCV Cassette technology cannot be overstated. It enhances the test's sensitivity and specificity, ensuring that each diagnosis is not just a result but a step towards a solution. Our commitment to advancing healthcare through technology is reflected in every aspect of the product, from its conceptualization to its real-world application. At QL Biotech, we believe in revolutionizing diagnostics to empower healthcare professionals and, ultimately, to improve patient outcomes.
PRINCIPLE
The Strep A Rapid Test Device/strip is a qualitative, lateral flow immunoassay for the detection of Strep A carbohydrate antigen in a throat swab. In this test, antibody specific to Strep A carbohydrate antigen is coated on the test line region of the test. During testing, the extracted throat swab specimen reacts with an antibody to Strep A that is coated onto particles. The mixture migrates up the membrane to react with the antibody to Strep A on the membrane and generate a color line in the test line region. The presence of this color line in the test line region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

PROCEDURE
- Allow the test device, reagents, throat swab specimen, and/or controls to reach room temperature (15-30°C) prior to testing.
1. Remove the test device from the sealed foil pouch and use it as soon as possible.
Best results will be obtained if the test is performed immediately after opening the foil pouch.
2. Hold the Reagent A bottle vertically and add 4 full drops (approximately 240 µL) of Reagent A to an extraction test tube. Reagent A is red in color. Hold the
Reagent B bottle vertically and add 4 full drops (approximately 160 µL) to the tube. Reagent B is colorless. Mix the solution by gently swirling the extraction test tube. The addition of Reagent B to Reagent A changes the color of the solution from red to yellow.
3. Immediately add the throat swab to the extraction test tube of yellow solution. Agitate the swab 10 times in the tube. Leave the swab in the tube for 1 minute. Then press the swab against the side of the tube and squeeze the bottom of the tube as the swab is withdrawn. Discard the swab.
4. Fit the dropper tip on top of the extraction test tube. Place the test device on a clean and level surface. Add 3 full drops of solution (approx. 100 µL) to the specimen well (S) and then start the timer.
5. Wait for the colored line(s) to appear. Read the result at 5 minutes. Do not read the result after 10 minutes.
INTERPRETATION OF RESULTS
- NOTE:
- 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 can not be determined by this qualitative test.
- Insufficient specimen volume, incorrect operation procedure, or performing expired tests are the most likely reasons for control band failure.
