Why We Exist

The Silent Majority Has No Medical Option

Youth soccer players

Picture this
Your child takes a hard hit at soccer practice. She says she feels fine. The coach isn’t sure.

What do you do?

Today, parents and coaches face a difficult choice: an expensive and inconvenient hospital visit with tests that miss most concussions — or just wait and hope that the symptoms don’t worsen.

The Problem
3 Million
Youth concussions (mild traumatic brain injury, mTBI) in the U.S. each year. Concussions cause real brain damage, especially when repeated.
80%
Go undiagnosed — no objective hospital test is available for sport concussion and specialized concussion clinics are not widely available.
$2,000+
Cost of an ER visit — and CT scan still misses 85% of mTBI and most sport concussions.
The Solution

Accurate. Non-Invasive. 15 Minutes.

BrainGuardian™ is a rapid saliva test that moves concussion detection from the hospital to the sideline, the school nurse’s office, and the home.

  • Simple to Use: A non-invasive saliva swab. No needles, no blood draws, no specialized training.
  • Rapid Results: A clear, visual readout in under 15 minutes.
  • Extended Time Window: Detects concussion from 1 hour up to 9 days after injury — unlike blood tests limited to 24 hours.
  • Affordable: Under $30 retail compared to $2,000+ for an ER visit.

Our Scientific Moat

We Don’t Just Test Saliva Fluid. We Test Saliva Cells.

Competitors rely on TBI biomarkers in blood or saliva fluid. Gaia Medical Institute has unlocked a fundamental biological advantage: novel TBI biomarkers in saliva cells.

By capturing the analytically available cellular TBI biomarker in saliva, our patented technology increases assay sensitivity by up to 100 times. This makes possible a simple visual test for TBI.

Youth Sports

Youth Sports

60 million youth athletes in the U.S. deserve a simple, affordable way to detect concussions when and where they need the test. BrainGuardian puts lab-quality diagnostics where the need is: locker room, home, sport clinic, or pediatrician office.

U.S. Army Medical Corps

Military Medicine

Service Members need a deployable, rugged BrainGuardian test for rapid, noninvasive, and objective detection of concussion and blast exposure in far forward field settings to prevent further brain injury.
