The PortaSCC®  line of somatic cell tests grew out of our pioneering work with remote site testing of white blood cells for human diagnostic applications — work that has yielded a US patent. In 2004, the PortaSCC® cow milk test was announced at the World Dairy Expo in Madison, Wisconsin, and by 2008 it was being distributed in over 60 countries worldwide.

After repeated requests from dairy goat producers for their own on-farm test, PortaCheck developed the PortaSCC® goat milk test and brought it to the market in January 2009. The next addition to our product line was the PortaBHB milk ketone test which hit the market in the spring of 2010. The latest product introduced by PortaCheck in April 2011 was the PortaSCC Quick test which met the needs of those customers looking for quicker results in a semi-quantitative test.

Dedicated Development - Thorough Testing

lab work

The PortaSCC® line of tests has been developed with a dedication to excellence. The scientists at PortaScience have continually improved it during four years of development. University researchers and extension agents have tested it in the lab and on the farm.

Experts agree that the PortaSCC® milk test is an effective, reliable tool for on-farm herd health management.  Click below for published studies.

The following PortaBHB milk ketone test study was completed at the University of Montreal and submitted to the 2011 AABP Conference.

Explanation of Technology

The PortaSCC® milk test is based on a chemical reaction between a dye on the test strip and an enzyme on the cells. This reaction causes the test strip to change color...the greater the number of cells, the higher the color intensity. The test strip can be compared visually to a color chart or read in the digital reader (cow test only) to obtain an approximate cell count. Since this test is based on enzyme activity which degrades over time, it is important to use fresh milk that is no more than 8 hours old.
