Laboratory result concept sets are collections of standardized terms, codes, and concepts used to represent the results of laboratory tests conducted on patient samples (such as blood, urine, or tissue samples). These concept sets help organize and categorize laboratory test results, ensuring that they are recorded and analyzed consistently across different healthcare systems, research studies, and clinical settings.

Laboratory tests are essential for diagnosing, monitoring, and managing a wide range of medical conditions. The results from these tests provide valuable insights into a patient's health status, helping healthcare providers make informed decisions regarding treatment, prevention, and follow-up care. Laboratory testing may include hematology tests, chemistry tests, microbiology tests, immunology tests, endocrinology tests, and toxicology tests.
