Each test request (order) requires preapproval by the CDC Parasitic Diseases Branch. Please contact parasiteslab@cdc.gov to request preapproval to submit specimens. The preapproval for your request will include important details about current submission requirements and forms.
Some assays for detection of parasitic diseases at CDC remain 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.
Strongyloides infection is best diagnosed with a blood test. Strongyloides infection may be diagnosed by seeing larvae in stool when examined under the microscope, but it might not find the worms in all infected people. This may require that you provide multiple stool samples to your doctor or the laboratory.
