Overview
The Dual Amylase / IgA LFD allows simultaneous measurement of two key biomarkers — salivary alpha-amylase (a marker of sympathetic nervous system activity) and secretory IgA (a marker of mucosal immune function) — from a single saliva sample.
Why Dual?
Together, sAA and sIgA provide a comprehensive picture of both stress load and immune status, helping practitioners make better-informed decisions about training and recovery.
