Therefore, this article provides you with the best methods on how to test your ketone level and why you need to test your ketone levels, and many more.

Reasons for testing your Ketones Levels

Ketones are a very powerful source of energy for the liver and other body functions.

During ketosis, the body breaks down healthy fats to build up energy.

Testing your blood ketones is essential for weight loss and to check your ketone level when you are living with diabetes.

Actually, when the body has inadequate insulin, your organs can produce ketones to boost your insulin level, especially for diabetes people.

There are three most common conditions that may influence you to test for your ketone level are:

  1. Any time your blood sugar is over 17 mmol/l (300 mg/dl)

When your blood sugar arises to over 17mmol/l, then it is the right time to test your ketone level.

Remember the earlier the better. Sometimes you may not know until you check your blood sugar level which may give you a clue to do further testing of your ketone level.

            2. In case your sugar levels have repeatedly been over 13 mmol/l (230 mg/dl)

when your blood glucose reading persists over 13mmol/l, you can go further and test your ketone level.

This may be a sign of your ketone levels increasing. You need to check your ketone level in this case.

  • Beta-hydroxybutyrate available in the blood
  • Acetoacetate present in the urine

The three types of ketones in the body can be measured in your breath, blood, or urine using different equipment.

Methods to Check ketones levels in the body

There are three effective methods to test your ketone level if you are following ketogenic diet.

They are discussed as follows.

  1. Testing for ketones in blood 

Blood ketone meter is used to check the level of beta-hydroxybutyrate in the blood to indicate ketosis levels.

How to test blood ketone using a blood ketone meter?

This equipment work the same way the glucose meter works.

If you know how to use a glucose meter, then this is not a big issue.

Here we go,

  1. Put a blood ketone strip into the meter
  2. Prick your finger using the lancing device and placed a small drop of blood on a strip that is inserted into the meter
  3. Allow blood to the ketone strip
  4. relax for some minutes for the reading to validate
  5. Now, under control discard the test strip

It will show you the level of beta-hydroxybutyrate in your blood.

However, this equipment is very expensive.

           2. Testing for ketones in urine at Home

The presence of ketone level that is acetoacetate in urine is measured using the ketone urine strips.

  4. check the instructions and  compare the color of the test area to the color chart on the side of the tub of strips
  5. Note that, any color changes after the set time frame  should be disregarded

The strips will change to pink or purple depending on the level of acetoacetate present in the urine.

Precisely, a darker color indicates that you have a higher level of ketones.

The good news is that ketone urine strips are easy to use and not very expensive.

The ketone test results readings should be as follows;

  • Under 0.6 mmol/L – This is a normal blood ketone value for a healthy person
  • 0.6 to 1.5 mmol/L – This ketone test result indicates that more ketones are being produced than normal. this can vary with time, therefore, you need to test again later to see if there is any change.
  • 1.6 to 3.0 mmol/L – The readings indicate that your body is producing excess ketones that can lead to a risk of ketoacidosis. Therefore, you need to seek medication if possible
  • Above 3.0 mmol/L – The Highest level of ketones that is very dangerous and require immediate medical  attention 

Which is the most accurate ketone test kit for ketone testing at home?

Using the most accurate ketone test kits is all you need.

From the list above, the most accurate ketone test kit is the blood ketone test kit followed by the ketone urine test kit and breath ketone kit test.

However, the blood ketone test kit is very expensive
