How to read this marker
Assay-specific. Acute infection, injury, and chronic inflammation may elevate.
The wider testing context
Autoimmune tests are not interpreted as simple high/low values. Pretest probability, titer, pattern, repeatability, symptoms, and organ findings matter.
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.

Approved by Dr. Daniel Purser, MD · PW-LABS-1.0. The source laboratory’s interval remains separate.
