Line 13:
Reference ranges that are given by this definition are sometimes referred as ''standard ranges''.
Since a range is a defined statistical value ([[Range (statistical)]]) that describes the interval between the smallest and largest values, many prefer to use the expression reference interval rather than reference range.
Regarding the target population, if not otherwise specified, a standard reference range generally denotes the one in healthy individuals, or without any known condition that directly affects the ranges being established. These are likewise established using reference groups from the healthy population, and are sometimes termed ''normal ranges'' or ''normal values'' (and sometimes "usual" ranges/values). However, using the term ''normal'' may not be appropriate as not everyone outside the interval is abnormal, and people who have a particular condition may still fall within this interval.
