At What Other Times Should Blood Glucose Levels Be Measured

Blood glucose should be measured any time you feel unwell or think your blood sugar level is too high or low.

If you have Type 1 diabetes and have more than 20mmol/l of glucose in your blood, you should use a urine strip to check for the presence of ketones.

If ketone bodies are present in your urine, it’s a warning sign of diabetic acidosis. If this is the case, you should consult your doctor immediately.
