Negative acute-phase reactant; affected by liver function and nutrition.

The wider testing context

Iron studies are most useful as a pattern. Collection time, fasting status, inflammation, liver disease, and supplementation can shift results.

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.
