Critical Values

Critical values may imply a life-threatening situation for the patient and must be brought to the immediate attention of the physician and/or the patient care staff responsible for the patient. Prompt notification of potentially life threatening test results is important to ensure appropriate care is administered. Critical values are established for a normal population, though in some instances may not be considered “critical” when related to particular disease states. Interpretation of test results and determining if a result is critical to a particular disease state is the responsibility of the requesting physician.
