Quinolones (QNS) Rapid Test Strip Quick Safety Test for Milk
Quinolones (QNS) Rapid Test Strip
Store at 2-8℃ in dry environment.
Expiry date: 12 months
The test strip is used for detecting Quinolones family in raw
commingled cow milk above or below tolerance and/or safe levels.
The kit is a competitive colloidal gold immunoassay method. Sample
is added to sample hole, if there is Quinolones (QNS) in samples, it
will combine with marked antibodies, preventing the marked
antibodies from combining the Quinolones (QNS) antigens of NC
Kit sensitivity: 20/50 ppb (ng/ml) (Final detection limit)

【Milk Sample Preparation】
1. Collect milk sample from butch, or farm
2. Make sure the milk has no clot.

3. Take the milk sample, drop 200ul (about 4-5drops) into the
sample-well, and thoroughly dissolve the milk with reagents for
5 minutes till the milk presents pink color.
4. Insert the test strip into the sample-well, read the results
after 5 minutes.
Negative(-): control line(C) display red, test line(T) color is
deeper than the control line or the same as the C line, the
result shows that (QNS) concentration is less than detection
Limits or not containing (QNS).
Positive(+): control line(C) display red, test line(T) color is
shallower than the control line or no color, the result shows
that (QNS) concentration is higher than detection Limits.
Invalid: control line (C) doesn’t display, it means the
