How to read this marker
Morning collection preferred for men. Method and age matter; confirm unexpected low values.
The wider testing context
Most sex-hormone values require age, collection time, cycle phase, menopausal status, pregnancy status, assay method, and exogenous hormone context.
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.
