Interventions

Type I diabetic participants take their usual insulin dose and provide blood and urine samples at baseline and for up to 24 hours. Non diabetic participants are administered intravenous (IV) Actrapid insulin 0.05iu/kg at visit 1, 70g oral glucose at visit 2 and placebo at visit 3. Blood and urine samples are collected at each visit at baseline then for up to 24 hours. There is a 5 day washout period between visit 1 (insulin administration) and visit 2 (glucose administration).
