Pre-approval prior to submissions will be required. Please contact dpdx@cdc.gov for current submission requirements and forms.
All other assays for serological, molecular, or characterization of parasitic diseases—and Trichomonas susceptibility testing—at CDC remain temporarily offline. We are working to restart additional testing as soon as possible for each test and will update this communication as soon as we are able.
CDC offers consultation to healthcare providers in the absence of diagnostic testing. Healthcare providers needing assistance with diagnosis or management of suspected cases of parasitic diseases may contact CDC’s Parasitic Diseases Hotline at (404) 718-4745, or e-mail parasites@cdc.gov.
