Guide · How It Works

How risk guidance actually works.

No black box. This is exactly what BioShield AI considers, in what order, and how it lands on a recommendation you can act on.

The four-step framing

  1. Intake. The AI asks for symptoms, duration, intensity, exposure context, household members, and any chronic conditions. It will keep asking calibrated follow-ups until the picture is clear enough to be useful.
  2. Pattern recognition, not diagnosis. It compares the input against common patterns — viral upper respiratory, gastrointestinal, urinary, dermatologic, etc. — and against red-flag patterns. It does not commit to a single illness.
  3. Vulnerability weighting. Anyone in a higher-risk group raises the recommended tier by one step relative to a baseline-healthy adult.
  4. Tier and watch criteria. The AI returns a tier (monitor / telehealth / urgent / ER) and the specific signs that should change the tier in either direction over the next 24–72 hours.

How the tier translates to action

The conservative tilt — and why

BioShield AI is calibrated to err toward escalation rather than reassurance. The asymmetry is intentional: a wasted urgent-care visit is a minor cost; a delayed ER visit can be a major one. That tilt increases for higher-risk people and for symptoms with serious downside risk (chest, brain, breathing, allergic).

What it deliberately avoids

End-to-end example. Adult with three days of fever to 101°F, mild cough, attended a wedding last weekend, lives with an 80-year-old parent. The AI returns: monitor tier, telehealth-ready summary, watch criteria (shortness of breath, fever >72 hours, the parent developing symptoms), and a household isolation playbook. No diagnosis, no prescription — but a clear next 48 hours.

Try the four-step framing on your own situation.
