1. Very stable reproducibility.
2. Quick and rapid result in 5 minutes.
3. Interpretation is easy.
4. High sensitivity - 0.45 ppb (fish, shrimp, chicken, pork); 2 ppb (whole egg, milk).

The Quinolones antibiotics(QNS) are often used for treating and preventing the spread of disease caused from animals and fish farming in high concentration. In order to prevent the adverse effects which are caused from the residue QNS damage the public health, lots of countries trend to avoid using it in poultries and seafood farming, and also strictly execute Quinolones residue relative examination and monitoring projects of imported meat and seafood products.
The Quinolones Rapid test kit is based on the specific immuno-chemical reactions between antigen and antibody. It relies on the competition between Quinolones residues in the sample and the Quinolones immobilized on T line on the membrane for the Quinolones antibody-dye conjugate. Since the drug has been presenting in the sample, it will compete with the drug immobilized on T line, to the limited amount of dye-antibody. As a sufficient amount of drug in the sample is presenting, the drug will saturate the antibody. Consequently, it will show an extremely light or even invisible T line, indicating a positive result. On the other hand, if there is a negative sample (or the amount of the residue drug is lower than the minimum detectable concentration), it will generate two obvious lines in both the T and C line section.
