Description
✨ Overview
The GSL Cortisol Saliva Home Test Kit measures cortisol from a simple saliva sample collected at home. Salivary cortisol reflects the free, biologically active form of cortisol that circulates in your body. Your sample is analyzed in our LC-MS/MS lab for accurate assessment of your stress hormone level. This test provides information about cortisol and is not a diagnosis or a substitute for medical care.
🎯 Who this test is for
- People who prefer non-invasive saliva testing over blood draws
- Busy individuals wanting a quick snapshot of cortisol without leaving home
- Those monitoring stress-management or lifestyle changes
- Anyone sensitive to needles who still wants lab-grade cortisol data
🧬 Biomarkers measured
This test measures free, biologically active cortisol in saliva and cortisol metabolites, reflecting the portion of cortisol that is not bound to carrier proteins.
