High specificity in a test indicates that it:

High specificity in a test refers to its ability to correctly identify those individuals who do not have the disease, which is measured by the proportion of true negatives among all those who do not have the condition. When a test has high specificity, it means that it accurately sorts out healthy individuals without misclassifying them as having the disease, thereby minimizing false positives. This characteristic is crucial in screening and diagnosing diseases, as a test with high specificity helps to ensure that individuals are not wrongly labeled as having a condition they do not have. Thus, option B aligns perfectly with the definition and purpose of high specificity in medical testing, demonstrating its effectiveness in distinguishing between the presence and absence of a disease.
