Capillary Blood Glucose - Target Range 

It is important to know what capillary blood glucose (CBG) targets are aimed for.  

Generally: 

• Default target CBG is 6-10mmol/L.
• Consider 8-12mmol/L for:
  • Elderly and frail patients.
  • Patients with reduced / no hypoglycaemia awareness.
• Consider 8-15mmol/L for patients on an end-of-life pathway.
• Consider more liberal targets if clinical circumstances indicate e.g. cognitive / behavioural / psychiatric issues.
