The body needs glucose (a kind of sugar from food) for energy. If it doesn’t get the glucose it needs, it starts burning fat. When fat is burned it produces a waste product called ketones. Ketones can build up in the blood and urine. This buildup can cause a dangerous condition called ketoacidosis. It’s for this reason that you should check for ketones at times when you are most at risk.
Check for ketones when any of the following is true:
Your blood sugar is above 300 mg/dL (milligrams per deciliter).
You are ill or under stress.
You have diarrhea (loose stool) or stomach pain.
You are very thirsty or need to urinate often.
You have a dry mouth.
You feel sick or nauseated, or you have vomited.
Check for ketones by using testing tablets or strips. Different types of test kits are available from your local pharmacy.
Depending on the type of test you buy, you can check for ketones in your urine or in your blood.
Record your test results in a notebook so that you can show them to your doctor.
Contact your doctor if you test positive for ketones.
Follow the package directions carefully.
Use a clean container (one washed with soap and water) to get a sample of your urine.
Place the test strip in the urine sample or pass the strip through your urine stream.
Gently shake excess urine off the strip.
Wait for the strip to change color. The directions will tell you how long to wait.
Compare the strip with the color chart on the bottle or package. This gives you a range for the number of ketones in your urine.
Record your results.
Use the meter and blood ketone strips as directed by your doctor.
