Quinolones Rapid Test Strip is a one-step lateral flow immunochromatographic assay that determines a qualitative level for the presence of quinolones and is intended for use in raw milk. the total test can be finished within 5 to 20 minutes, this method is suitable for the rapid on-site test.
Limit of Detection:
5-80g/kg(g/kg=ppb)

Raw milk
Interpretation of the Results
A color line always appears in the upper section of the test strip to indicate that the test strip is working properly. this line is the Control Line (C). A line in the lower section of the test strip indicates the test results. this line is the Test Line (T).
Negative Sample (-):2 lines are visible. the intensity of test line (T) is greater than or equal to control line (C) indicates the sample contains quinolones less than limitations. (Please see image above).
Positive Sample (+): the intensity of test line (T) is less than control line (C) or only control line (C) is visible. this indicates the sample contains quinolones greater than or equal to the limitations. 
Invalid results:
If there is no line in control zone, the test is invalid and the sample should be re-tested by using a valid test strip.
