How to read this marker
Consider altitude and iron/B12/folate status. Pregnancy requires trimester-specific ranges.
The wider testing context
Typical adult starting intervals. Review altitude, smoking, hydration, pregnancy, age, ethnicity, medications, and local analyzer 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.
