How to Report COVID-19 Laboratory Data
Summary:
The Coronavirus Aid, Relief, and Economic Security (CARES) Act and its June 4 implementation guidancepdf iconexternal icon require every COVID-19 testing site to report every diagnostic and screening test performed to detect SARS-CoV-2 or to diagnose a possible case of COVID-19 (e.g., molecular, antigen, antibody) to the appropriate state or local public health department, based on the individual’s residence. Laboratories that currently report directly to CDC should continue sending these data to CDC. Email questions to DLSinquiries@cdc.gov.
The public health response to COVID-19 depends on comprehensive laboratory testing data. These data will contribute to understanding COVID-19’s impact and testing coverage and can contribute to the identification of supply chain issues for reagents and other materials. The information below outlines reporting requirements for laboratories.
Who must report
All COVID-19 diagnostic and screening testing sites must
- have a Clinical Laboratory Improvement Amendments (CLIA)external icon certificate – compliance, accreditation, waiver, or provider performed microscopy
- meet all requirements to perform testing, including only using FDA-authorized test systems according to their instructions for use, and
- report the results of the COVID-19 diagnostic and screening tests that they perform to the appropriate state or local public health department.
COVID-19 testing sites are defined as
- laboratories that perform clinical diagnostic or screening testing under CLIA,
- non-laboratory COVID-19 diagnostic or screening testing locations, and
- other facilities or locations offering COVID-19 point-of-care diagnostic or screening tests, or in-home diagnostic or screening tests.
Testing sites must report data for all diagnostic and screening testing completed, which includes molecular, antigen, and antibody testing, for each individual tested. These data must be reported daily, within 24 hours of test completion, to the appropriate local, state , territorial or tribal health department, based on the individual’s residence.
Testing sites that perform COVID-19 surveillance testing on de-identified samples, regardless of their CLIA status, should not report the results of their surveillance testing to local, state, territorial, or tribal health departments. If at any time a facility intends to report a patient-specific test result, it must first obtain a CLIA certificate and meet all requirements to perform testing. For more information, see the Center for Medicare and Medicaid Services’ (CMS) Research Testing and Clinical Laboratory Improvement Amendments of 1988 (CLIA) Regulationspdf iconexternal icon and the CDC Division of Laboratory Systems’ CLIA webpage.
For information about the CLIA Certificate application process, see CMS’ How to Apply for a CLIA Certificate, Including International Laboratoriesexternal icon webpage.
For definitions of COVID-19 diagnostic, screening, and surveillance testing, see CDC’s Interim Guidance for Use of Pooling Procedures in SARS-CoV-2 Diagnostic, Screening, and Surveillance Testing.
The Association of Public Health Laboratories (APHL) has developed the National ELR Flat File and HL7 Generator Toolzip iconexternal icon to assist laboratories with reporting.
How to report
Laboratory data elements may be reported in the following ways:
- Submit laboratory testing data directly to state or local public health departments according to state/or local law or policy. Data must be sent using existing reporting channels to ensure rapid initiation of case investigations, and concurrent reporting of results must be shared with ordering provider or patient, as applicable.
- Submit laboratory testing data to state and local public health departments through a centralized platform (such as the Association of Public Health Laboratories’ AIMS platformexternal icon), where the data will then be routed to the appropriate state and local authorities and routed to CDC after removal of personally identifiable information according to applicable rules and regulations.
- Submit laboratory testing data through a state or regional Health Information Exchange (HIE) to the appropriate state or local public health department and then to CDC as directed by the state.
Public health departments will submit de-identified data to CDC on a daily basis, using either Health Level 7 (HL7) messaging or the CDC-provided CSV format.
For more information on the data elements included in the June 4 HHS guidance, as well as technical specifications that support implementation, see HHS’s COVID-19 Lab Data Reporting Implementation Specificationspdf iconexternal icon.
What to report
Complete laboratory data must include the following data elements for state and jurisdictional health departments.
- Test ordered – use harmonized LOINC codes provided by CDC
- Device Identifier
- Test result–use appropriate LOINC and SNOMED codes, as defined by the Laboratory In Vitro Diagnostics (LIVD) Test Code Mapping for SARS-CoV-2 Tests provided by CDC
- Test Result date (date format)
- Accession # / Specimen ID
- Patient age
- Patient race
- Patient ethnicity
- Patient sex
- Patient residence zip code
- Patient residence county
- Ordering provider name and NPI (as applicable)
- Ordering provider zip
- Performing facility name and CLIA number
- Performing facility zip code
- Specimen Source – use appropriate LOINC, SNOMED-CT, or SPM4 codes, or equivalently detailed alternative codes
- Date test ordered (date format)
- Date specimen collected (date format)
The following additional demographic data elements should also be collected and reported to state or local public health departments.
- Patient name (Last name, First name, Middle Initial)
- Patient street address
- Patient phone number with area code
- Patient date of birth
- Ordering provider address
- Ordering provider phone number
To protect patient privacy, any data that state and jurisdictional health departments send to CDC will be deidentified and will not include some patient-level information. The deidentified data shared with CDC will contribute to understanding COVID-19’s impact, positivity trends, testing coverage, and will help identify supply chain issues for reagents and other materials.
How to report using standard terminology
CDC has posted a LOINC In-Vitro Diagnostic (LIVD) Test Code Mapping Guide for COVID-19 test results for tests with emergency use authorization from the U.S. Food and Drug Administration (FDA) that can be used by clinical laboratories and instrument manufacturers. This specification supports the use of standardized LOINC and SNOMED Clinical Terms (CT) codes to improve the accuracy of reporting tests for the SARS-CoV-2 virus. Using these harmonized LOINC and SNOMED-CT codes helps ensure that the same type of test is represented uniformly across the United States.
For those COVID-19 tests that have not yet received FDA emergency use authorization, CDC encourages test developers and laboratories that use COVID-19 tests to work together to obtain appropriate and interoperable LOINC and SNOMED-CT codes for reporting purposes.
LOINC codes must be used to represent the “question” a viral test asks of a specimen (e.g., does this specimen have SARS-CoV-2 RNA?), and SNOMED-CT codes must be used to represent the diagnostic “answer” (e.g., what was detected?). More background on these terminology standards can be found here:
Whenever possible, laboratories must use standard codes that already exist. Before requesting a new code, search the list of currently available LOINC external icon for SARS-CoV-2 tests. If a LOINC test code cannot be identified whose attributes appropriately match the test for which coding is needed, new terms can be submitted, and a new code requested through the LOINCexternal icon.
Technical assistance for electronic reporting
Electronic reporting options are available to reduce the burden on providers reporting test results. Laboratories that are not currently reporting electronically to their state or local health department and want assistance in establishing electronic reporting can contact CDC’s Emergency Operations Center, Laboratory Reporting Working Group at eocevent405@cdc.gov.
Frequently Asked Questions on Laboratory Data Reporting Guidance for COVID-19 Testing
New guidancepdf iconexternal icon from the Department of Health and Human Services (HHS) specifies what data must be reported to comply with the COVID-19 laboratory reporting requirement in CARES Act Section 18115. The new guidance requires facilities and ordering providers to gather more complete patient demographic information to send to state and local public health departments. State and local health departments will then forward the de-identified data to CDC.
