BHBCheckTM blood ketone test is an accurate and affordable test that uses one drop of blood to provide
quantitative results in 5 seconds. The test measures β-Hydroxybutyric Acid (BHBA) concentration in blood which is the “gold standard” for sub-clinical ketosis testing in dairy cows.

Test Principle
The test strip contains a reagent with an enzyme that measures the level of D-3-hydroxybutyrate in whole blood. This method is based upon the oxidation of D-3-hydroxybutyrate to acetoacetate by the enzyme D-3-hydroxybutyrate dehydrogenase. The reaction generates hydrogen ions which are converted to an electrical current and measured by the meter.
