Product Description
The PortaBHB milk ketone test is a semi-quantitative dipstick for the detection of sub-clinical ketosis in dairy cows.
- 1 minute reaction time
- 2 year shelf life when stored at room temperature.
- Cow-side test. Squirt milk onto test strip and read results.
The reagent pad on the test strip contains an enzyme that converts BHB to acetoacetate. This reaction generates hydrogen ions that reduce nitrotetrazolium blue to formazan, which is purple in color. The darker the purple color, the higher the concentration of BHB.
Notes
- If the test strips or milk samples have been refrigerated, allow them to reach room temperature before testing.
- If the milk has been standing for some time, make sure to mix it thoroughly before performing the test.
- Close the strip container tightly after use. Test strips are light and moisture sensitive.
- This test is designed for use with milk only. Test results with other fluids have not been studied.
Storage and Handling
- Store at 2 ̊C – 25 ̊C (36 ̊F – 77 ̊F). Store refrigerated whenever possible. Product shelf life is 2 years from the date of manufacture if stored at room temperature.
- Avoid using test strips that have discolored after extended storage.
- The reagent pad on unused test strips should be yellow.
- Keep the test strip vial tightly closed.
- Do not touch reagent pad on the test strips.
Interpretation of Results
- 0-99 μmol/L – normal (-)
- 100-199 μmol/L – questionable (+/-)
- 200-499 μmol/L – positive (+)
- 500 + μmol/L – positive (++)
