Arrows are not verdicts

Stop 1/8

箭头不是判决

The easiest mistake when a lab report lands in your hands is panicking at a single arrow. Three ground truths first.

1. Reference range is not healthy range. The 'normal interval' printed on the sheet is usually the central 95% of the population that lab has measured — it describes 'most people', not 'the healthiest people'. And most people's metabolism is not in great shape.

2. A single arrow says little; the pattern is what matters. Triglycerides slightly up + good cholesterol slightly down + liver enzymes slightly up + uric acid up + fasting insulin high — each alone 'isn't disease', but together they point to one upstream driver: insulin resistance. That convergence is more diagnostic than any single marker.

3. Trends beat snapshots. One draw is affected by sleep, stress, recent meals, menstrual phase, medications. Same-lab, same-fasting-condition trends are far more reliable than an isolated value.

This island covers routine chemistry in four panels: lipids, glucose metabolism, liver enzymes, kidney + uric acid. Reference values and interpretation tables sit on the depth pages; the first screen is mechanism only.
