A ketones in blood test measures the level of ketones in your blood. Ketones are substances that your body makes if your cells don’t get enough glucose blood sugar. Glucose is your body’s main source of energy. Ketones can show up in blood or urine. High ketone levels may indicate diabetic ketoacidosis DKA, a complication of diabetes that can lead to a coma or even death. A ketones in blood test can prompt you to get treatment before a medical emergency occurs. A ketones in blood test is mostly used to check for diabetic ketoacidosis DKA in people with diabetes. DKA can affect anyone with diabetes, but it is most common for people with type 1 diabetes. If you have type 1 diabetes, your body does not make any insulin, the hormone that controls the amount of glucose in your blood.

As well as being an effective way to lose weight, studies have shown this high-fat, low-carb diet may deliver other health benefits, including reducing seizures in children with epilepsy and protecting brain function. The keto diet is similar to the Atkins and other low-carb diets in that it involves drastically reducing the amount of carbohydrates you eat and replacing them with fat. Carbohydrates usually account for at least half of the typical American diet. By restricting your carbohydrate intake, your body is forced to burn fat instead of glucose for energy — putting it into a metabolic state called ketosis. During ketosis, fat is converted into ketones in the liver. These ketones are released into your bloodstream, where they are used by your muscles and other tissues for fuel. People with diabetes regularly test their blood sugar levels to avoid blood sugar spikes and hypoglycemia dangerously low blood sugar.
As you go through this guide, keep in mind that many of the normal reference ranges were developed on populations eating a high carb diet, and therefore in some cases you may need to adjust your concept of normal for a patient following a low-carb lifestyle. In addition, many normal values vary based on the individual lab, the patients gender, size, etc. We try to clarify where these caveats are most important. ALT is a liver enzyme test measuring hepatocellular damage. It can often be elevated in metabolic syndrome and obesity most commonly due to non-alcoholic fatty liver disease NAFLD. Excessive alcohol intake and liver infections such as hepatitis can also cause elevations. Once the weight loss is over, this elevation tends to disappear and ALT usually normalizes.
