diagnostic accuracy

Diagnostic accuracy refers to how well a test or method correctly identifies whether someone has a particular condition or not. It includes two key aspects: sensitivity (the ability to detect true positives) and specificity (the ability to identify true negatives). A highly accurate diagnostic test produces few false positives (indicating illness when there isn't one) and few false negatives (missing actual cases). Overall, diagnostic accuracy measures the reliability and effectiveness of a test in correctly classifying individuals, helping healthcare providers make informed decisions for appropriate treatment.
