SUPPORT BOUNDARIES

Drug Test Guide publishes careful, source-backed tools for understanding testing concepts, biomarkers, detection windows, cutoffs, and uncertainty. It is built for orientation, not for predicting a specific lab, court, workplace, medical, treatment, probation, or forensic outcome.

Primary Tool

The EtG Field Guide

The current guide is an interactive EtG calculator and reference for urinary ethyl glucuronide timing, common cutoff levels, and model limits.
