Antibiotics Residue In Milk Rapid Test(Quinolone Rapid Test) INTENDED USE Quinolone Test is a competitive immunoassay for the semi-quantitative detection of the presence of Quinolone in milk. Cut-off: 50 ppb Assay Time: 10 - 15 min Sample: milk PRINCIPLE OF THE ASSAY Quinolone Test is based on competitive lateral flow immunochromatographic assay. The Quinolone conjugate in the test zone will capture the immuno-gold, when there is very little dissociative Quinolone in the sample. A visible red test band indicates a negative result when the control line shows that the card is valid. The test band will be not visible if Quinolone is present in concentration of 50 ppb and above which explains a positive result.
