The document discusses the CDC's LabHIT program which aims to facilitate laboratory test ordering and reporting in electronic health records. The program develops and disseminates standardized terminology and code sets to support clinical data capture and interoperability. It also works with various stakeholders to engage in terminology development, promote semantic interoperability, and ensure usability and patient safety. The long-term goal is a single national reference database for recommended vocabulary sets to achieve full-scale interoperability for laboratory data.
