If you’re reading this, then it’s likely that you’re looking to learn more about ketones, why they are important, and how you can check your ketone levels. We’ve got you covered! Read on to learn everything you need to know about ketones. 

What is a ketone? A ketone is a chemical compound produced by the liver when it breaks down fats. Our bodies usually use glucose as its fuel source. But when it isn’t readily available, our bodies use ketones as an alternative source of energy. 

If you feel tired or weak, it might be a sign that your body has started producing ketones. It’s important to keep an eye out for this so that you keep your health and wellness in check, because a high amount of ketones might indicate that you are imposing too many restrictions in your diet. 


If you have diabetes and experience any of the following, then it is critical that you check the ketone levels in your urine:

  • High levels of blood sugar
  • Frequent bathroom visits
  • Feeling more thirsty than usual
  • Having a dry mouth
  • Vomiting
  • Diarrhea

Even if you don't have diabetes and experience any of the following, it’s still worth checking your urine’s ketone levels:

You can check ketones in your body with  ketone tests strips, which provides you with information on your wellness. If you’re on a ketogenic diet, you can check whether you are in ketosis using ketone tests. 

Ketone tests use a sample of either your urine, blood, or breath. But today, we’ll focus largely on checking ketones in urine through at-home urine tests.

How to test ketone levels?

Ketones can be tested at home using a urine ketone strip, blood ketone strip, or blood ketone meter. However, blood ketone test strips and meters are more expensive, and can be more difficult to use.

At-home urine strips are one of the best ways to test ketone levels in your body because they are much more affordable and easier to use.

How to check ketones in urine?

A urine ketone test can be used to detect ketones in the urine. When these urine tests come into contact with your urine, they change color. The color that it turns into  corresponds to your urine's concentration of ketones, ranging from zero to high. The darker the color after urinating on the test, the higher your ketone level.

When you take a urine ketone test, it can be difficult to read your own results, because there is always room for error when trying to determine your urine ketone levels based on a change in color.
