What are the Sensitivity and Specificity of Tests?
Sensitivity and specificity are key measures of a test's performance. Sensitivity refers to a test's ability to correctly identify those with the disease (true positive rate), while specificity refers to its ability to correctly identify those without the disease (true negative rate). A highly sensitive test may produce false positives, and a highly specific test may produce false negatives. Balancing these two aspects is crucial for accurate diagnosis.
