In one case it was a urinary flow test (uroflowmetry). The results go to a lab and then the doctor gets the summary. Was able to diagnose the issue, prevalence, etc. and educate myself about treatment and risks before seeing a doctor. Papers gave me distributions of flow by age, sex, etc. so I knew it was out of range.

In another case I uploaded a CSV of CGM data, analyzed it and identified trends (e.g. Saturday morning blood sugar spikes). All in five minutes on my phone.
