Biological age tests are interesting trend signals, not magic truth machines. The useful part is logging test dates, methods, protocol changes, and context.
| Field | Why |
|---|---|
| Test name and date | Different clocks measure different things; keep method and lab together. |
| Result and units | Biological age, pace score, percentile, confidence range if available. |
| Protocol changes | GLP-1s, peptides, supplements, sleep, exercise, nutrition, alcohol, medications. |
| Context | Illness, travel, poor sleep, weight change, training load, stress. |
| Conventional labs | A1c, ApoB/lipids, blood pressure, hs-CRP, liver/kidney markers if ordered. |
