What does a critical value in laboratory reporting indicate?

A critical value in laboratory reporting signifies a test result that indicates a significant risk of morbidity or mortality. This means that the results are outside of established normal limits and suggest a potentially life-threatening condition that requires immediate clinical attention. Such values are vital in guiding healthcare professionals to make rapid decisions regarding patient care.

For instance, significant deviations in parameters like blood glucose levels, potassium levels, or hemoglobin might prompt urgent interventions to avert serious complications or death. Therefore, recognizing and effectively communicating critical values is essential in ensuring prompt patient management in healthcare settings. This understanding underscores the importance of laboratory results in clinical decision-making and patient safety.
