Founded 2010 in Lee’s Summit, MO by veteran laboratory executives Cory Zuehlsdorf & Cristian Saez. We spent our initial years developing the science, validating our methods, and implementing compliance to obtain our CAP Accreditation and CLIA License. In 2014 we co-developed the most innovative blood serum separation and transportation container used for screenings today. In 2017 we expanded our innovations in capillary analysis with our micro sample collection and testing technology that offers a venipuncture like test menu from a specimen collected via fingerstick.

CoreMedica’s specimen analysis capabilities span across multiple collection modalities and methods, fingerstick or venipuncture. Specimens, from all across the country, are processed at our single site laboratory daily. Our centralization allows for industry leading turn around time, consistency and quality.​
