RATI mobile app is developed for ICMR to collect Rapid Antibody Test being conducted through technicians. The district administration/Health department will register the collection centres and will also add accounts for their technicians using the portal https://covid19cc.nic.in. Once registered on this portal, the technician will be able to use this mobile app to collect the data of persons undergoing Rapid Antibody Test being conducted in India. The mobile app can be used by only registered technicians only. Once the test result is ready, the technicians will also update the test results using the app. Any person undergoing for the test again has to be entered using the Repeat test option which will also save the entry of person's details.
