How to read this marker
Diet, kidney function, microbiome, timing, and assay affect results.
The wider testing context
These tests generally lack universal cross-platform reference intervals. Any Purser Wellness interpretation must specify the exact laboratory, method, specimen, and clinical purpose.
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.
A question to bring to your visit
Which parts of the TMAO rule apply to my report’s method, units and collection conditions, and what other findings should we review alongside it?
Approved by Dr. Daniel Purser, MD · PW-LABS-1.0. The source laboratory’s interval remains separate.
