About COVID-19 Test Repository (CTR)

The COVID-19 Test Repository (CTR) serves as a one-stop repository and single source of truth for COVID-19 test results. It aggregates and centralises test results from multiple laboratories and makes these results available in a standardised and consistent manner to multiple user groups, including healthcare professionals, in a timely manner. This enables prompt public health actions to be taken.

Tightly integrated with 10 downstream systems

Interpret results in a standardised coded manner

Real time view of more than 27 million test results

Results flow swiftly in one-minute intervals


COVID-19 Test Repository (CTR) at a glance


As COVID-19 spread, there was a need for quick access and near real-time view of an individual's laboratory test results to detect the outbreak and respond with contact tracing and quarantine measures. To aid the national effort against COVID-19, there was also a pressing need to digitise and consolidate an aggregated view of the COVID-19 test results status that is both comprehensive and timely.


The CTR is integrated with the National Electronic Health Record to pull and centralise tests results from all public healthcare institutions and MOH assigned private laboratories. Within the system, there are two user-facing components – CTR Viewer and CTR Dashboard, which allow access to individual test results and visualisation of COVID-19 test result data to support operations planning, management reporting and analytics.


CTR minimises the need for manual compilation of the test results from various laboratories. Freed of these time-consuming tasks, staff could be redeployed to support other operations. The tool also helps to close information gaps, providing insights on evolving COVID-19 testing situation with the display of tests and results completed by each laboratory and each healthcare facility.

Future Outlook

As the functionality and usefulness of the CTR grow amid the active mass testing strategy for the wider population, more healthcare facilities and clinicians tapped on CTR to access COVID-19 test results to manage their patients.

  • What does the CTR Viewer do?

    The CTR Viewer is a browser that allows access to test results of individuals to support day-day ground operations in incidence tracking of positive, negative and potential cases that require retesting and to support expeditious tracing. It minimised the need for manual compilation of test results from various laboratories.

  • What does the CTR Dashboard do? 

    The CTR Dashboard is a visualiser of composite COVID-19 test result data to support operations planning, management reporting and analytics. This data helps in calculating the estimated downstream capacity required and facilitates planning for upcoming test strategies. CTR Dashboard went through multiple updates to improve the data presentation and averaged a new release almost every week in the early days of COVID-19.
