Strep A rapid test accurate

Concerns about the tests’ specificity and sensitivity have limited their use, but findings from a new meta-analysis that included 48 studies investigating the effectiveness of RADTs for diagnosing GAS pharyngitis compared to bacterial culture of a throat swab have shown that the tests have high diagnostic accuracy.

Overall the tests had a sensitivity of 0.86 and specificity of 0.96. The authors found that the newer molecular techniques and the newer optical immunoassay were the best-performing tests in terms of specificity and were as sensitive as a throat swab.
