How Accurate Is Your Rapid Flu Test?
Diagnostic accuracy of the digitally interpreted rapid influenza A and B antigen tests (DIA) was better than the traditional rapid flu tests, 77-80% sensitive vs. 53-54% sensitive. In children compared to adults, the sensitivity was 18.5 points higher for flu A and 32 points higher for flu B with the traditional rapid test; 12 and 25 points higher for the DIA respectively; 2.7% points higher for nucleic acid amplification tests (NAATs). NAATs were about 95% sensitive overall. All tests had specificity of about 98%.
