How to Test for Ketones

Ketones are a byproduct of incomplete fat metabolism. A ketone blood test is necessary if you are diabetic and have symptoms of diabetic ketoacidosis, which include nausea, vomiting and abdominal pain. The following steps describe the procedure for the ketone urine test, using test strips.

Instructions

1

Read the instructions that accompany the testing strips and follow the manufacturer's directions. The strips are chemically treated and change colors when dipped in the urine.

2

Use a clean container to collect your urine sample. Testing for ketones in the urine doesn't have to be done using sterile techniques, but do try to keep the sample as clean as possible. Avoid contaminating the urine with pubic hair, menstrual blood or stool.

3

Remove one of the strips from the bottle, dip it into the urine sample and remove it immediately. Tap the excess urine off, keep the test strip horizontal and wait about 15 seconds for the results.

4

Compare the color of the strip after it reacts with the urine with the color chart on the side of the bottle. This test is less precise than a blood test, but is usually safe for someone who is on a low carbohydrate or high protein diet and is concerned that they may not be getting enough carbohydrates. The test is also useful for a pregnant woman who has developed a temporary form of gestational diabetes and must monitor her urine periodically for ketones.

5

Follow your physician's instructions regarding the results of your test.
