- According to the American Diabetes Association, casual plasma glucose concentration ≥200 mg/dl (11.1 mmol/l) is indicative of type 2 diabetes in children. Casual is defined as any time of day without regard to time since last meal. Furthermore, concentrations of ≥140 mg/dl are considered to indicate pre-diabetes or Impaired Glucose Tolerance (IGT)37. Therefore, we envision that the web interface will provide system notifications at both of these values.
