how to track blood work in excel
At a glance
Track blood work in Excel or Google Sheets with columns for test date, marker, value, unit and the laboratory reference range. Keep a separate dated protocol log and compare like-for-like results over time. A before-and-after difference does not establish that a supplement or diet caused the change.

Build a useful longitudinal record
Starting point: Manual Fragmented Data. Preserve the original report, including its units and test date.
Next step: Custom relational tracking template.
Track, don’t assume causation: Compare dated results alongside protocol changes, illness, exercise and other context. A change over time alone cannot prove that a protocol worked.
Frequently asked questions
How do I calculate biomarker change over time in a spreadsheet?
When the baseline is non-zero and units match, use ((new value - baseline value) / baseline value) * 100. This describes a change, not its cause; do not calculate a percentage from a zero baseline.
