Patients often go to different doctors, and there can be different lab tests performed. Different doctors use different labs, for example, Quest Diagnostics, LabCorp.
The labs have all your information. Some have advanced features, for example plotting the glucose level of the past 6 months, etc.
However, there is no way to aggregate all the information from different labs.
Is there a service that aggregates this information? Say a user upload lab reports themselves.
