Lab Results Tracking Matrix

A bloodwork tracker designed to follow lab trends across multiple healthcare systems, prevent duplicate testing, and counter diagnostic overshadowing.

Why track your own lab results

When searching for a diagnosis across multiple specialists, medical providers often only see the lab results ordered within their own network or portal. By maintaining a centralized, cross-provider lab history, you can:

How the sheet works

Each row is one test, with its standard reference range beside it. The columns to the right are for each blood draw: the date, who ordered it, and your result. Highlight anything out of range so it stands out at a glance:red for high, blue for low.

What to say when you bring it in

I keep a personal tracking sheet of my bloodwork across different lab networks so we can look at long-term trends rather than single snapshots. As you can see, on [date], my ferritin dropped down to [X] alongside my fatigue flare, even though my general hemoglobin was still technically within the normal window.

The 23 tests on the sheet

These are the ranges printed on the sheet. Reference ranges differ a little from lab to lab, so always compare a result with the range printed on that report.
