Heat distribution unit. The Heat Distribution Unit (HDU), also known as a Heat Interface Unit (HIU), provides domestic hot water (DHW) and space heating to properties that are serviced from district heating or centralised boiler plants.
Called hypoglycemia, this deficiency of glucose in the blood is considered critical at, or below, 40 milligrams of glucose per deciliter of blood, or 40 mg/dL. However, this figure must be adjusted individually, as the exact level at which an a person develops symptoms varies.
The second result of your 2âhour blood glucose test measures your glucose two hours after you drank the glucose drink. This level should be less than 140mg/dl. Normal levels of glucose mean that your body is able to use glucose the way itâs supposed to. High levels of glucose mean that you have impaired glucose tolerance (IGT). This means that your body has a hard time using glucose, and puts you at risk for developing diabetes.
