Diafarm CMT-test should also be used for checking somatic cell count in milk after mastitis treatment. Diafarm CMT-test should not be used when the cow produces raw milk (colostrum), should not be used before the third day after calving. Diafarm CMT-test should not be used after drying-off has been started. Diafarm CMT-test liquid is an in vitro diagnostic test that will not provide a conclusive

Instruction for test performance
1. Clean each teat separately.
2. Discard the foremilk.
3. Apply milk samples from each quarter into the individual cavity of the paddle dish.
4. Discard excess milk in order to collect 2-3 ml milk (approx. ½ teaspoon) to react with equal amounts of Diafarm CMT-test.
5. Add 2-3 ml Diafarm CMT-test to each paddle.
6. By making circular movements with the paddle dish the content will be mixed. At the same time observe for reaction like viscous change of the mixture. Read the result within 10 second. The reaction may disappear after a short while. In case of doubt the test should be repeated.
7. Rinse paddle carefully after each test.
