The terms sensitivity and specificity may not appear in the manufacturers information sheets, but are often reported as positive percent agreement and negative percent agreement. Sensitivity may also be measured by calculating the limit of detection, which is the lowest detectable number of virus copies in a sample at which the test will return a positive result at least 95% of the time.
