Thirty-one test orders are currently listed as unavailable, requiring labs to seek alternative testing pathways or coordinate with public health partners.
The Centers for Disease Control and Prevention (CDC) has identified multiple infectious disease laboratory tests as currently unavailable in its online test directory, highlighting potential gaps in access to specialized public health testing.
The CDC’s Infectious Diseases Laboratory Test Directory, which provides a centralized listing of orderable tests and submission requirements for public health labs, includes a section for “currently unavailable test orders.”
According to the directory, 31 test orders are listed as offline as of April 3, with several noted as “diagnostic testing temporarily paused.” In some cases, the CDC directs laboratories to seek alternative testing through commercial providers or the agency’s Antimicrobial Resistance Laboratory Network.
The CDC’s infectious disease labs primarily support state and public health laboratories by providing reference and specialized testing that may not be widely available in clinical settings. Specimens are typically submitted through state or local public health labs rather than directly from hospitals or independent clinical laboratories.
The unavailable tests include categories such as fungal identification and other specialized diagnostics, where the agency notes that testing is paused but technical consultation may still be available.
More broadly, the CDC indicates that tests listed in the directory represent its current testing capacity, and only those included are available for submission.
The agency advises laboratories to review test availability before submitting specimens and to coordinate with public health partners when alternative testing pathways are needed.
The update comes as the CDC continues to maintain and revise its test directory, which serves as a key resource for clinical and public health laboratories navigating specimen submission, test requirements, and turnaround expectations.
