In a healthy individual, the normal blood ketone levels are typically less than 0.6 mmol/L.
Levels of 0.6 to 1.5 mmol/L indicate a state of increased ketone production, commonly seen during fasting or low carbohydrate diets.
Levels above 1.5 mmol/L may indicate a more significant state of ketosis.
Values above 3.0 mmol/L can be a sign of diabetic ketoacidosis (DKA) in diabetics, a condition that requires immediate medical attention.
It’s important to interpret ketone levels in the context of the individual’s overall health and any underlying medical conditions.
