Help Launch CortiCheck: A Lifesaving Tool for Rare Disease Warriors

We’re confident in our incredible science team and fully believe in CortiCheck’s potential to become a reality.

While every innovation comes with some level of uncertainty, we’re moving forward with care, skill, and determination.

This project was born from the needs of our own rare disease community, and your support is helping us take a critical step toward a safer, more empowered future for thousands of patients.

Please note that contributions to this campaign are non-refundable, even if unexpected challenges prevent the monitor from being completed or sold.

CortiCheck™

Real-Time Cortisol Testing. In Your Hands.

No prescriptions. No waiting. No guesswork. CortiCheck is the first handheld cortisol monitor built by patients, for patients—designed to prevent adrenal crisis, support steroid tapering, and empower real-time decision-making.

Why CortiCheck?

Every year, thousands of people with adrenal insufficiency are hospitalized due to cortisol crashes.
And yet—there’s still no FDA-cleared at-home cortisol test.

CortiCheck changes that.

✅ Portable, user-friendly design

✅ Fingerstick blood test with smartphone integration

✅ OTC-accessible: No prescription required

✅ Designed for: Adrenal Insufficiency, Addison’s, Chronic Steroid Users, and more
