CDC Specimen Test Order and Reporting (CSTOR)

The CDC Specimen Test Order and Reporting (CSTOR) Web Portal is the central online resource for CDC Infectious Disease (ID) laboratory partners, including the Association of Public Health Laboratories (APHL)external icon, to submit specimens and access test results and reports.

CSTOR Web Portal allows infectious disease specimen submitters to:

  • Request and obtain approval to send samples to CDC for testing
  • Submit specimen data and create shipping paperwork online
  • Validate specimen data and provide submitter support to correct errors and complete missing information
  • View and download test results and reports easily and securely online

Streamlining the Specimen Submission Lifecycle

There are six modules to help submit, track, and access specimen information and test results. These include:

  • Request Test Order – Manage test requests to CDC; CSTOR is updated with the latest Test Order Directory
  • Submit Specimens – Submit specimen data via a web form or import a batch of specimens using any Excel file
  • Ship Package – Create manifests and packing slips for specimen shipments
  • Check Status Track the status of test order requests, specimen submissions, and packages
  • View Reports – View and download reports securely, and access test result data in a variety of formats
  • Manage Organization – Administrators may add and remove users in their organization and edit data

An alternative to CDC Specimen Submission Form 50.34, CSTOR removes manual processes and tracks the status of each submitted specimen. Connected to CDC’s Enterprise Laboratory Information Management System (ELIMS), CSTOR accelerates specimen receipt, reduces processing time, and expedites delays.
