Answer

The following 3 rapid diagnostic tests are considered of low complexity and may be used in physicians’ offices:

  • QuickVue Influenza A+B test (Quidel)

  • ZstatFlu (ZymeTx)

  • QuickVue Influenza test (Quidel)

The QuickVue tests provide results in 10 minutes or less; the ZstatFlu test provides results in 20 minutes. Genetic and antigenic changes in the virus can adversely affect diagnostic test performance; thus, these tests should be monitored annually. [40]

In June 2014, the FDA also approved the Alere i Influenza A & B Test, a new point-of-care influenza test that delivers highly accurate molecular results in less than 15 minutes. [41, 42] The test, which extracts and analyzes DNA and RNA strands to detect sequences associated with bacterial and viral infections, has a sensitivity of greater than 90% for both influenza A and B. Although other influenza detection tests that produce results in about 15 minutes are already on the market, those tests rely on antigen detection and their sensitivity ranges from 50% to 70%. [41, 42]
