Tips for an accurate result
These estimates are general-population formulas, not medical advice — check with a professional for anything that affects a health decision.
Keep a simple log of results over time; a single app or notebook is more useful than remembering numbers from memory.
Use consistent measurement conditions each time (same scale, same time of day) so results are comparable over time.
Compare a result against a normal range rather than treating it as a single pass/fail target — most of these figures work as ranges, not thresholds.
