Please be advised that the Centers for Disease Control and Prevention (CDC) is retiring the 50.34 Specimen Submission Form application on October 30, 2026, in an effort to modernize and streamline the specimen submission process. The CDC Specimen Test Order and Reporting (CSTOR) Web Portal will remain the CDC's preferred method of specimen submission. If your organization is onboarded to CSTOR, no further action is needed. If you require support, please contact the CSTOR Team at CSTOR@cdc.gov.
CDC accepts specimens from state public health laboratories and other federal agencies for analysis. As of July 2024, private healthcare providers and institutions may submit specimens directly to CDC with local state health department laboratory (state, county, city) approval.
Specimen submission methods
Specimen management activities at CDC include the receipt, categorization, and distribution of specimens from public health facilities to CDC laboratories for reference diagnostic testing and research studies. State-of-the-art technology is used to provide data and information summaries that are crucial in the assessment of public health trends and epidemic dynamics on a national scale.
There are currently two methods for submitters to submit specimens to CDC for testing:
- The CDC Test Order and Reporting (CSTOR) Web Portal (preferred)
- The CDC 50.34 Specimen Submission Form
Who may submit specimens
State health departments and other federal agencies may submit specimens for reference testing to CDC. With state health department approval, private healthcare providers, hospitals, and laboratories may submit specimens directly to CDC via the CDC Specimen Test Order and Reporting (CSTOR) Web Portal. All specimen submissions to CDC must receive approval by the individual state health department, unless specific tests have been pre-approved in CSTOR.
If a local health department is unable to determine where and how to submit a specimen, they should forward the specimen to their state health department.
