What BioShield AI can and cannot do.

What BioShield AI is built to do well

BioShield AI is a structured risk-framing assistant. Within that scope, it does several things consistently:

• Frame next steps. Given a description of symptoms, exposure, household setup, and risk factors, it tells you whether the situation reads as monitor-at-home, telehealth, urgent care, or ER.
• Surface red flags. If anything in your description matches an emergency pattern, it will flag it directly and recommend faster action.
• Account for vulnerability. Older adults, infants, pregnancy, immunocompromised individuals, and people with chronic conditions get explicitly weighed.
• Translate symptoms into watch criteria. Instead of telling you what is happening, it tells you what to watch for over the next 24 to 72 hours and when to escalate.
• Help you prepare for a clinician visit. Structured intake — duration, intensity, exposure, medication list — that you can carry into telehealth or urgent care.
• Stay calm. Most symptom checkers fire red flags at everything; BioShield AI tries to be calibrated rather than alarmist.

What BioShield AI will not do

• It will not diagnose. No "you have flu," "you have COVID," or "this is appendicitis." Symptoms can match many illnesses; only a clinician with examination, labs, and history can responsibly diagnose.
• It will not prescribe. Medication choice, dosing, and risk depend on your full medical record. It can describe over-the-counter categories generically, but specific prescription advice is out of scope.
• It will not replace a clinician. If a situation requires hands-on examination, imaging, or labs, BioShield AI will say so and route you toward in-person care.
• It will not guarantee accuracy. Like all language-model based tools, it can occasionally misread inputs or miss important context. It is one structured input into a decision, not the decision.
• It will not promote products. Risk framings, escalation criteria, and content are not influenced by sponsors or advertisers.

What it should not be used for

• Active emergencies. If a symptom is severe or rapidly worsening, call your local emergency number first, then talk to BioShield AI later if you want.
• Self-managing serious chronic disease without a clinician. Heart failure, diabetes, transplant care, cancer treatment, complex psychiatric conditions — these need ongoing professional management.
• Replacement for prenatal care, pediatric well-child visits, or routine preventive care.
• Authoritative interpretation of lab results or imaging.

How it handles uncertainty

Health questions almost always carry uncertainty. BioShield AI is built to surface that uncertainty rather than mask it. When a description is ambiguous, it asks clarifying questions instead of guessing. When a symptom could be benign or could be serious, it gives you the watch criteria for both branches and tells you what would tip the balance.

How it handles bias and edge cases

The AI is intentionally tuned conservatively. That means: when in doubt, it suggests the higher-care tier rather than the lower one. For higher-risk groups — infants, pregnancy, older adults, immunocompromised individuals — that conservatism increases. We accept the cost of "you went to telehealth and they said it's fine" as far better than the cost of missing something that needed in-person evaluation.
