Abstract:
Directigen Flu A + B and Binax NOW Flu A and Flu B tests detected 33 (55.9%) and 31 (52.5%) of 59 influenza-positive samples, respectively. In children under 2 years of age, sensitivity increased to 75% for both tests. Three samples tested falsely-positive for influenza B using Binax NOW.
