WebSpecificity equation: Specificity = (TN) / (TN+FP) For instance, for a test with 95% sensitivity, that means that 95% of results will be true positives . and 5% will be false negatives. A specificity of 93% means that 93% of all true negatives will test . negative, with 7% falsely testing positive. Below, the columns are the count of true ...
