Systems and methods for providing test results include receiving a request from a user computing device for historical test result data associated with a patient for a test type at a computing system. In response to receiving the request, the computing system accesses the historical test result data for the patient and test type, which includes a test result value and a test range. The computing system generates graphical data, in part, by normalizing the historical test result data by fitting the test range to a chart subrange corresponding to a predetermined range for the test result (e.g., a normal outcome of the test). The computing system then transmits the graphical data to the user computing device for rendering and display at the user computing device.
