United4Rare is a mission-driven, for-profit consulting and medtech company dedicated to transforming the rare disease landscape. With over 45 years of combined experience, we specialize in connecting clinical innovation with the real needs of rare disease patients.

Our work is grounded in decades of adrenal insufficiency advocacy and system change. We now apply that experience to advancing new cortisol diagnostics, including the developing CortiCheck initiative. We help innovators and research teams understand real world adrenal needs, align around shared goals, and create the pathways needed to move future testing solutions forward.

For investors and collaborators, United4Rare brings credibility, access, and a clear path forward in adrenal insufficiency innovation. For clinicians and research partners, we offer the insight needed to understand real world adrenal needs and build meaningful engagement. Together, we can advance cortisol diagnostics with precision, alignment, and a shared commitment to improving adrenal care.

CortiCheck is our developing initiative to create the first handheld rapid cortisol blood test for real time adrenal monitoring. Through the Global Adrenal Testing Consortium, we are bringing together clinicians, researchers, engineers, and industry partners to shape its design, feasibility, and clinical pathway. We are actively seeking stakeholders who want to help build CortiCheck and move adrenal diagnostics forward.
