Blood Ketones testing

Ketones are acids which can quickly make you feel very unwell. They may make you vomit or you may become breathless.

If Ketones persist you may develop Diabetic Ketoacidosis (DKA). DKA may cause your child to become extremely unwell and they may require urgent hospital treatment.

Blood Ketones may still be produced when a child is ill even if blood glucose levels are low.

The Freestyle Optimum Neo-meter tests for blood Ketones. The advantage of measuring Ketones in the blood is that an increased level can be detected earlier than in the urine, and trends can be followed over several hours.

Therefore please follow these guidelines:

  • Always test for blood ketones if your child has an unexplained or unexpectedblood glucose levels above 14mmol/l
    Always test for blood ketones when your child is illeven if blood glucose levels are low
    Always test blood ketones when your child is vomiting or feels sick,even if the blood glucose level is low


Below 0.6 mmol/l– levels below 0.6 mmol/l are in the normal range. Follow your healthcare professional’s advice before you make any changes to your child’s diabetes medication programme.

Between 0.6 and 1.5 mmol/l– when the blood ketone level is between 0.6mmol and 1.5 mmol/l and the blood glucose level is higher than 14 mmol/l this may indicate the development of a problem that may require medical assistance. Follow your healthcare professional’s instructions.

Above 1.5 mmol/l– when blood ketone level is higher than 1.5 mmol/l and blood glucose level is higher than 14 mmol/l, your child may be at risk of developing diabetic ketoacidosis (DKA). Contact your healthcare professional immediately for advice.
