The wider testing context

Routine chemistry intervals plus kidney staging. eGFR and albuminuria categories are clinical classifications, not simple normal ranges.

Using this reference

This is the approved adult, nonpregnant baseline unless the rule explicitly states otherwise. Keep the performing laboratory’s reference interval separate from this Purser Wellness rule. Match units and review the specimen, method, timing, medicines and relevant clinical context before interpreting a result. These pages do not calculate a personal high/low status or prescribe treatment.
