post meal 150 a1c 6.1 but no symptoms of diabetes in child

Two continuous glucose monitoring systems are currently available for clinical use. The system manufactured by MiniMed Medtronic involves inserting a subcutaneous sensor (rather like an insulin pump cannula) that measures glucose concentrations in the interstitial fluid for 72 hours. The glucose values are not available for evaluation at time of measurement — the data are downloaded to a computer in a physician's office after collection. The other system ("Glucowatch") measures glucose in interstitial fluid extracted through intact skin by applying a low electric current (reverse iontophoresis). This process can cause local skin irritation, and sweating distorts the glucose measurement. Both systems require calibration with finger blood glucose measurements. The main value of these systems appears to be in identifying episodes of asymptomatic hypoglycemia, especially at night.
