Pre‑biosigns (pre‑biological signals) are measurable changes in your body that appear before you feel sick — a slight drop in white blood cells, a tiny rise in liver enzymes, a change in nerve protein levels. They're not symptoms; they're data.
This tool tracks these signals across six organ systems, helps you spot dangerous patterns, and generates doctor‑ready scripts — so you can act before a crisis.
