The CDC has announced that over two dozen infectious disease laboratory tests, including those for rabies, poxvirus, Epstein-Barr virus, and varicella zoster virus, are now unavailable as of March 30, 2026. Some tests are temporarily paused, while others have been discontinued due to staffing reductions of 20% to 25% across the agency. Alternative diagnostic methods through commercial labs or state public health laboratories may be utilized. The updated Infectious Diseases Laboratory Test Directory outlines all relevant specimen and order protocols.
