# MedicalHistory.app > https://medicalhistory.app — Personal lab result tracker that extracts biomarker values from PDF blood test reports, tracks trends over time, and builds a private longitudinal health timeline across any provider or clinic. MedicalHistory.app is patient-facing software for individuals who receive lab reports across multiple clinics, portals, and time periods. Typical use cases include tracking blood biomarkers over years, preparing for clinician follow-ups, keeping a personal medical archive, and replacing manual spreadsheet tracking. Users upload lab report PDFs and doctor visit notes. The application extracts biomarker names, values, units, reference ranges and dates, and mapped values appear on the user's timeline automatically. Every value can be edited at any time, because lab naming, units, reference ranges and formatting vary across providers. MedicalHistory.app is not a healthcare provider. It does not provide diagnosis, treatment, or emergency medical advice. Educational content is not a substitute for licensed medical care. The product is independent and not affiliated with any hospital, clinic, laboratory, insurance company, pharmaceutical company, or government health system. ## What we do - [Upload and extract lab PDFs](https://medicalhistory.app/): Extract candidate lab results and biomarker values from uploaded PDF reports automatically. -
