Build a charting tool from blood test PDFs with Claude
Matt Stockton gave Claude his MyChart blood test PDFs and it produced a web app charting results over time and flagging abnormal values in about five minutes.
Done with Claude Code
What they did
Matt Stockton downloaded several recent blood test PDFs from MyChart, whose formats vary by test and year. He attached them to one Claude prompt with his age and gender. The prompt asked for an interactive browser tool that highlights abnormalities and recommended actions, and it invited Claude to ask questions first.
How it went
With limited prompting, Claude built an app that charted results over time, flagged abnormal values and added general health insights, all in about five minutes. He thinks a more detailed prompt would improve it.
Worth knowing
He stresses that this needs strong human guidance and oversight. It is not a replacement for doctors or enterprise-grade tools.
Try it yourself with Claude Code
I have blood test PDFs in [folder path]. Extract every result with its date and reference range, then build a simple local web page that charts each marker over time and highlights values outside the range. You are done when I can open the page and see the charts. Keep the data on my computer and do not upload it anywhere.
