6. Operation procedures

6.1 Take out the test card from Aluminum foil bag, use it in 1 hour.

6.2 Put the test card flatly, use dropper to drop 1~2 dropsof sample (or use micropipette to take 60 ul) in the Sample collect region vertically.

6.3 Wait for 3~5 min to read the result. (It’s valid in 10 minutes)

 

7. Test Result Interpretation

7.1 Negative: Red T line appears. It means there is no total aflatoxins residue in sample or the residue is lower than detection limit.

7.2 Positive:Red T line is invisible. It means the residue is higher than detection limit.

7.3 Invalidation: C line isn’t seen wine red.It means the test card is out of efficacy, out of date or improper operation. Please run the test again using another package. If the invalid tests keep happening, please contact the local distributor.   

 

8. Specificity

This product has no cross-reaction with chloramphenicol, streptomycin, tetracycline, sulfonamides, quinolones and other types of drugs.

 

9. Precautions

1) The test card can be used only once at room temperature, do not use test card out of expiry date.

2) Every test card and dropper is single use only, to avoid cross pollution.

3) Do not touch the white membrane surface in the middle of test card, avoid sunlight and fan blowing directly.

4) Tap water, distilled water or deionized water can not be taken as negative control sample.

5) Use this card to test again when getting positive result.

6) Because of sample difference, sometimes the T line color may be lighter or gray, but only red line appears, it can be judged as Negative.
