Basal rate

In biology, basal rate is the rate of continuous supply of some chemical or process. In the case of diabetes mellitus, it is a low rate of continuous insulin supply needed for such purposes as controlling cellular glucose and amino acid uptake.

Together with a bolus of insulin, the basal insulin completes the total insulin needs of an insulin-dependent person.

An insulin pump and wristop controller is one way to arrange for a closely controlled basal insulin rate. The slow-release insulins (e.g, Lantus and Levemir) can provide a similar effect.
