Background: It is aimed to detect the sensitivity and specificity of rapid antigen detection of group A beta hemolytic streptococci from throat specimen compared with throat culture. Specificity is compounded It may be helpful to define some terms here. 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. Of these, 95% = 180 will test positive. We continue to work to improve your shopping experience and your feedback regarding this content is very important to us.
