Submitting Specimens to CDC

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.
