Scantibodies Clinical Laboratory in Santee has manufactured medical diagnostic components from its Abraham Way campus since 1976, operating under California clinical laboratory license CLF 11679. The facility produces monoclonal and polyclonal antibodies, heterophilic blocking reagents, calibrators, and custom controls that feed into immunoassay platforms at reference laboratories including Sharp Rees-Stealy Santee Laboratory and clinical systems nationwide. A dedicated bulk serum department custom-formulates human and animal sera to specification, with every vial weight-checked before release. The immunoassay components manufactured at the Abraham Way facility are the type of reagent used in point-of-care testing panels at urgent-care endpoints including AFC Urgent Care Santee on Mission Gorge Road. The largest lyophilization operation on campus spans 2,756 square feet of freeze-dry shelf capacity rated for pharmaceutical-grade cycle protocols across multiple chambers.
