Electronic Laboratory Reporting


Informatics LogoThe Connecticut Department of Public Health (DPH) Infectious Disease (ID) Informatics Program will work with clinical laboratories to implement or maintain electronic laboratory reporting (ELR).

During the COVID-19 pandemic, the Department of Health and Human Services (HHS) posted guidance for the expansion of reporting of testing for SARS-CoV-2 to include point of care and other locations testing under a CLIA certificate of waiver. The Informatics Program implemented a CSV format reporting method for these locations as an alternate to reporting using HL7 that is generally used by CLIA certified laboratories to report SARS-CoV-2 and other lab reportable results via HL7 ELR. This guidance was shared and is summarized in Reporting of COVID-19 Test Results to the Connecticut Department of Public Health

Reporting requirements for COVID-19 test results are changed as of April 4, 2022, under new guidance from the HHS and these have been adopted by DPH. The new guidance for COVID-19 test result reporting for providers testing under a CLIA certificate of waiver and laboratories that are CLIA certified is here:

PROVIDER COVID-19 Testing Changes

LAB COVID-19 Testing Changes

For any questions about reporting COVID-19 test results, please email DPH.InformaticsLab@ct.gov and Informatics staff will assist you.

We are implementing a new CSV reporting solution for providers, Casetivity, in the near future. Additional information will be posted on this website or sent by email.

For hospital and other laboratories, we require using HL7-based ELR and not CSV files if possible. This is particularly important for eligible hospitals looking to meet promoting interoperability requirements as defined by the Centers for Medicare and Medicaid Services for 2022. To get started with HL7 ELR, please email  DPH.InformaticsLab@ct.gov. We will send you the necessary information to enroll in or continue to onboard for lab reporting via ELR.
