DPDx is a Web site developed and maintained by CDC's Division of Parasitic Diseases and Malaria (DPDM) that uses the Internet to assist laboratorians and pathologists in the diagnosis of parasitic diseases, both in the United States and abroad. Please remember that DPDx will not respond to inquiries that are outside the goals and objectives of this Web site.

Please include the following information along with your message:

  • Your name
  • Your affiliation
  • Your telephone contact number (optional)

If you have digital images or other documents, please attach them. When submitting digital images, we ask that you attach several images to better assist us in making an identification.

PLEASE NOTE: As of October 1, 2011, the DPDx Team will require a CDC Submission form to be filled out and submitted with images for diagnostic assistance, in order to receive a formal, written lab report. Since the form will be submitted electronically, the patient's name does not need to be included but two other unique identifiers (patient ID number, date of birth, etc) should be. To access the most recent form (CDC 50.34), please click here.

Please include the following additional information when submitting digital images for consultation:

  • Specimen ID code,
  • Mailing address for final reporting,
  • Type of specimen,
  • Date specimen was collected, stain used, and magnification of the microscopic field captured,
  • Presumed diagnosis, and
  • Any other pertinent data (e.g., pre or post Rx, travel history, etc.).

This assistance is free of charge (except for U.S. Federal agencies and the U.S. military). If you have an urgent case, please do not delay case management and treatment.

Please send your diagnostic request to dpdx@cdc.gov.
