What results indicate a somatic cell count of 400,000 to 1,500,000 in a CMT test?

In a California Mastitis Test (CMT), the formation of a distinct precipitate, but no gel, indicates a somatic cell count between 400,000 and 1,500,000 cells per milliliter. The CMT is designed to detect the presence of somatic cells, which are primarily white blood cells that increase in response to inflammation or infection in the udder.

When the somatic cell count falls within the range of 400,000 to 1,500,000, the test results show a distinct precipitate, which means there is a noticeable reaction that indicates an increase in somatic cells. However, there is no gel formation at this level, which distinguishes it from more severe conditions where gel formation is present, indicating an even higher somatic cell count typically associated with significant mastitis.

This level of response is critical for dairy producers, as it helps them monitor udder health and take necessary actions to manage mastitis in their herd. Recognizing the specific indicators of somatic cell counts through the CMT allows for effective herd management and milk quality assurance.
