Submitting Specimens to CDC
Specimen submission requirements for CLIA diagnostic testing are being updated. All submissions to CDC for CLIA diagnostic testing require pre-approval by the CDC Infectious Diseases Laboratory point of contact (POC) for the testing being requested.
Several test orders are also currently unavailable. Please click “More Info” for the full list.
CDC’s Infectious Diseases Laboratories accepts specimens from state public health laboratories and other federal agencies for analysis. Specimens from private healthcare providers and institutions should be submitted to the local state health department laboratory (state, county, city) for appropriate processing. The searchable Test Directory features an up-to-date list of orderable tests and provides information on specimen requirements, contact information, test turnaround times, and other supplemental information. Access the directory here or while completing a Specimen Submission Form.
