Provider and Laboratory Reporting
Guidelines for COVID-19

Summary of Recent Changes

On September 15th, 2023, CDPH adjusted COVID-19 reporting requirements to indicate all facilities must report nucleic acid amplification tests (NAAT)/molecular COVID-19 tests regardless of CLIA certificate type.

SARS-Cov-2, Influenza Virus A & B and RSV Result Reporting

  • Report results electronically within 24 hrs
  • Report positive and non-positive test results for SARS-COV-2, influenza virus A & B and respiratory syncytial virus (RSV) as specified in the below table:  
Laboratory-, hospital-, and pharmacy-based testing facilities such as clinical laboratories, hospital laboratories, commercial and public health laboratories, healthcare system and hospital-affiliated outpatient clinics, and retail pharmacies Community-based testing facilities such as skilled nursing facilities, long-term care centers, and independent provider offices
Molecular (NAAT*) tests Must report  Must report
Antigen Tests Must report
Do not report
*NAAT: nucleic acid amplification tests

Disease reporting is an essential part of the public health response to COVID-19. Not only is reporting COVID-19 required by law, but reporting also helps shape our response as the information is used to detect outbreaks, identify exposures in high risk settings, and inform the allocation of local resources. Timely and complete reporting of fatalities is necessary to characterize and communicate who is at highest risk of dying at home and in the hospital.

Thank you for reporting COVID-19.

Provider Reporting
Summary of Required COVID-19 Reporting for Providers
  • Providers at community-based testing facilities conducting NAAT/molecular tests (including but not limited to long-term care centers, skilled nursing facilities, prisons, physician offices, urgent care clinics, outreach clinics, and temporary patient care settings) are mandated to report results and may do so via CDC’s SimpleReport or CDPH’s SaPHIRE Portal (email CalREDIE_Onboarding@cdph.ca.gov for more information).
  • Healthcare providers must report COVID-19 associated deaths and all cases that meet the CDC definition of MIS-C.
  • All acute care hospitals (including general and long-term acute care hospitals) are required to provide a  line list of their COVID-19 positive inpatients.

If the patient’s residence is outside Los Angeles County, please do not send a report to LAC DPH. Please see Other Health Jurisdictions reporting information below.

COVID-19 Associated Deaths
Icon of the Death Report Form

Healthcare providers should report COVID-19 associated deaths. Deaths should be considered COVID-19 associated if COVID-19:

  • Directly preceded death,
  • Initiated the train of morbid events leading directly to death, or
  • Is a significant condition that contributed to the death


COVID-19 associated deaths must be reported by healthcare providers within 24 hours by:

If COVID-19 testing was performed, please attach/send the laboratory result slip along with the death report form.

Note that If COVID-19 played a role in a patient’s death, it is important to report it accurately on the death certificate. For more information on certifying deaths due to COVID-19, see the Los Angeles County Health Alert Network message dated July 3, 2023, and CDC’s guidance.


See the LAC DPH MIS-C webpage for more information about MIS-C.

Hospital Inpatient Reporting

All acute care hospitals, including general and long-term acute care hospitals, in Los Angeles County are required to provide a line list of COVID-19 positive hospitalized patients. No Emergency Department, Observation, or Outpatients should be included in this file.

See Daily Reporting of Hospitalized COVID-19 Positive Inpatients: Updated Data Submission Requirements and Guide for Acute Care Facilities in LA County for an overview of requirements plus detailed instructions regarding report/file preparation and design, submission, and FAQs.

Laboratory Reporting

Laboratory-, hospital-, and pharmacy-based testing facilities must report the following diagnostic tests within one (1) working day:

  • All SARS-CoV-2 nucleic acid amplification test (NAAT) results (positive and non-positive).
  • All SARS-CoV-2 results from non-NAAT viral test results (e.g., high throughput antigen testing) (positive and non-positive).

  • In addition, all entities performing SARS-CoV-2 whole genome sequencing (WGS) and/or molecular sequencing-based surveillance are required to follow the LA County Health Officer Order: SARS-CoV-2 Data Sharing and Reporting (see below). View Reportable Conditions: Notification by Laboratories to see all laboratory reporting requirements.

    All laboratories that test LAC residents must register with the California Department of Public Health (CDPH) for electronic laboratory reporting (ELR), regardless of the physical location of the laboratory. Information about how to establish an electronic connection with CDPH to route positive and negative COVID results to LACDPH can be found at the CDPH Health Information Exchange Gateway.

    Temporary reporting instructions for labs awaiting ELR

    1. Register your laboratory with Los Angeles County Department of Public Health, using this form, which can be emailed to Covid19TestQI@ph.lacounty.gov.
    2. After receiving registration confirmation, laboratories are required to do the following daily:

    For each person tested, laboratories are required to do the following SARS-CoV-2 results daily:

    • Fax each positive NAAT and antigen lab result slips to (310) 605-4274.
    • Email as a single daily batch a report of all non-positive NAAT and antigen results (e.g. negative, indeterminate) using a template that will be emailed after a test file is submitted. The following can be used for guidance in utilizing this template:

    SARS-CoV-2 Whole Genome Sequencing
    The LA County Health Officer issued an order requiring entities that are performing SARS-CoV-2 sequencing and molecular testing on specimens collected from residents of LA County public health jurisdiction to register with LAC DPH, report information about sequenced samples as directed, report findings of public health significance, and submit specimens upon request. For more information see the Whole Genome Sequencing FAQ. View the LA County Health Officer Order: SARS-CoV-2 Data Sharing and Reporting.

    Reporting Outbreaks or Case Clusters

    In LA County, all facilities outlined in the County Health Officer Order are required to report clusters of COVID-19 cases.

    Other Health Jurisdictions

    COVID-19 must be reported to the jurisdiction where the patient resides.
