Accuracy refers to the closeness of test results to the true or standard value of the measured parameter. Achieving accuracy is essential to ensure reliable and valid diagnostic tests. For instance, incorrect glucose measurements can lead to improper diabetes management and misdiagnosis. It is important to note that accuracy is different from precision, which reflects the consistency or reproducibility of test results. While precision is significant, accuracy is paramount in clinical settings since it directly impacts patient care.
