Generic synonyms: Quantity

### Definition of Parameter

1. n. A term applied to some characteristic magnitude whose value, invariable as long as one and the same function, curve, surface, etc., is considered, serves to distinguish that function, curve, surface, etc., from others of the same kind or family.

### Medical Definition of Parameter

1. A variable whose measure is indicative of a quantity or function that cannot itself be precisely determined by direct methods, for example, blood pressure and pulse rate are parameters of cardiovascular function and the level of glucose in blood and urine is a parameter of carbohydrate metabolism.
