CDC's bird flu test faces reliability issues, experts warn

The CDC's H5N1 bird flu test has faced issues, including a faulty component that sometimes requires retesting. Despite this, the agency claims the tests are reliable and has developed a workaround. The outbreak has infected at least 13 farmworkers this year, raising concerns about the reliance on a single testing supplier. The CDC plans to distribute 1.2 million improved tests soon, pending FDA approval.
