Scaling new heights in neurologic insights

We’re harnessing technological breakthroughs to transform how brain and spinal cord cancers are detected

As a team of neurosurgeons, scientists, and entrepreneurs, we founded Belay Diagnostics to help those diagnosed with brain or spinal cord tumors find the right path forward. Given the obstacles traditional methods of detecting brain or spinal cord malignancies present to both patients and their care teams, we see our proprietary molecular testing technology as a way to bridge the gap between today’s standards and a more clinically convenient future.

While there are options available to diagnose a malignant brain or spinal cord tumor, each presents potentially undesirable limitations in sensitivity, specificity, expense, and possible risks involved. By identifying and analyzing DNA in cerebrospinal fluid, our technology could lead the way to an economical, minimally invasive, and highly accurate alternative.
