Annual Research Roundup

It’s that time of year when we bring research to you. We did the heavy lifting, scouring multiple peer-reviewed journals to find papers about the topics important to you. Let’s get reading! (Curious which papers were hot last year? Check out 2020’s research roundup.)

Here’s to a year of great research and we look forward to featuring more research in the future.

Instapath was founded in 2017 by the same engineers and scientists who developed the original prototypes. Our vision is to enable patients to immediately know their cancer diagnosis instead of waiting days or weeks for the results. Instapath builds microscopy platforms to improve patient care in the form of faster turnaround times and prevention of high risk and costly repeat biopsy procedures. Further, our goal is to provide users with a seamless, modernized digital pathology workflow with tools to complete all pathology evaluations needed to provide the most precise and efficient diagnoses for patients.
