Ketone
test strips
Presence of
ketones in the urine is an
indication of the body start metabolizes fat. Both
diabetics and persons on low-carbohydrate diets may test their
urine for ketones on a daily basis.
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.
Ketone test
strips usage procedure:
- 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.
