Ketone test overview
Normally no ketones are found in the urine. In low carbohydrate metabolism situations, ketones appear in the urine in large amounts before serum ketones are elevated. The reagent detects as little as 5-10 mg/dl acetoacetic (ketones) in urine.

Ketone testing procedure
Ketone urine-testing strips has a small absorptive pad, it contains a chemical reagent that changes color (usually within 15-20 seconds) in the presence of ketones in the urine. The keytone-strips change to varying shades of pink and purple. The ketone-strips' container has a scale on the label, with illustrative blocks of color to help you identify the shade of your ketone-testing strip.

Keytone test strips handling procedure
The chemical reagent on the ketone test strip is very sensitive to moisture, including moisture in the air, so be sure to keep the lid of the container tightly closed at all times. And be sure that your hands are dry when using strip. Once the container seal is opened, ketone strips has a shelf-life of only 6 months for reliable result.

  • It is best to collect first morning urine sample in a clean, dry container.
  • Confirm that your hand is dry, other wise dry it.
  • Take out one reagent strip from the bottle and immediately close container tightly, to minimize exposure to moisture.
  • Immerse the tip of the reagent strip in the urine sample and then takeout immediately to avoid dissolving of reagent in the strip.
  • Run the edges of strip against the rim to avoid urine spills.
  • Wait for some seconds (15 – 20 seconds) for the reaction to carry over and color change to take place.
  • Compare the color change of reagent strip to that of the color chart provided in the container.
