Sensitivity refers to how well a test
identifies people who truly have strep throat. A highly
sensitive test minimizes false negatives and catches
nearly all infections.
Specificity measures how accurately a test
identifies people who do not have strep throat. A
highly specific test reduces false positives and helps
avoid unnecessary treatment.
Our rapid strep test has a sensitivity rate of 98.5% and a
specificity rate of 93.4% for detecting
group A strep. On average, this means false negatives
occur about 1.5% of the time, while false
positives occur approximately 6.6% of the time.
