API call to incorporate past results in report

Hi Everyone,

I am trying to customise a report using Senaite Impress that shows a biomarker monitoring report. A patient needs to take sequential tests in 3-month cadence. Does anyone know how to incorporate past test results into a Senaite impress report? I looked into the JSON API, but it seems like there isn’t a way to search for previous test results based on the patient’s MRN. The deprecated Senaite Health module had a function to return past results, but the feature is no longer available in Senaite Patient.
