Milk Sample Preparation

1. Collect milk sample from butch, or farm

2. Make sure the milk has no clot.

3. Milk at room temperature, don’t heat or freeze.

4. Thoroughly mix with the reagent before testing.

3. Take the milk sample, drop 200ul (about 4-5drops) into the sample-well, and thoroughly dissolve the milk with reagents for 30seconds minutes till the milk presents pink color.

4. Insert the test strip into the sample-well, read the results after 5 minutes.
