LOINC
LOINC (Logical Observation Identifiers Names and Codes) is a universal language that healthcare systems use to name and identify medical tests, measurements, and observations. Think of it as a standardized dictionary that helps different hospitals and medical systems understand each other when they share patient information. For example, one hospital might call a blood sugar test "glucose level" while another calls it "blood glucose," but LOINC gives them a single, common code to use. This makes it easier to share patient records between different healthcare providers and ensures everyone is speaking the same language when discussing medical tests.
