Mosaic Diagnostics (formerly The Great Plains Laboratory) has operated from 9221 Quivira Road since 2007. The company is a CLIA-certified clinical laboratory specializing in advanced diagnostic testing for complex chronic health conditions: metabolic, nutritional, and toxicological testing serving healthcare practitioners nationwide and internationally. In June 2025, Mosaic Diagnostics was acquired by Microbac Laboratories. Mosaic is vacating the Quivira Road facility in December 2026. The building’s continuous use as a fully operational diagnostic laboratory means the lab infrastructure, HVAC, plumbing, electrical, and waste systems have been maintained and upgraded to meet clinical laboratory standards throughout its occupancy.
