Ketone strips will also be available in the pharmacy section of most large grocery stores. The strips are also available through major online retailers.

You can purchase disposable plastic cups at any grocery store. Check the dental section or the section containing plastic plates and plastic ware.

If you’re urinating while seated, try not to dip the ketone strip into the toilet water. This will dilute the urine and ruin the sample.

Waiting too long to read the results—or not waiting long enough—can result in a misleading reading.

It may be the case that the color of your urine strips fits in between 2 of the color squares on the packaging. In this case, assume that the higher reading is a more accurate result.

The colors will also correspond to numerical values: 0. 5, 1. 5, 4. 0, etc. These measure the amount of ketone in your urine in units of milligrams per deciliter, or units of millimoles per liter. Healthy people not on a keto diet will have extremely low levels of ketone in their urine.

This can include cutting out more carbs, or consuming more protein.

Once your body has become used to burning stored fat for energy, it will have less ketone to eliminate via urine.

Other signs of high blood sugar include: weakness, nausea or vomiting, extreme thirst, and difficulty breathing.
