Clinical Decision Tree Explorer

Direct-to-consumer lab testing access has expanded a lot, but people ordering their own panels generally don’t have the clinical reasoning context a doctor would apply — which symptoms and goals actually lead to which specific test, and why one panel variant over a similarly-named other. Existing symptom checkers are built around acute, today symptoms, not the chronic, persistent patterns this kind of self-directed user actually wants to investigate.

The idea: pick one chronic-symptom decision tree, hand-build it from real clinical sources — including disambiguating between confusingly similar test variants (three different Vitamin D panels, say) — and give it an explorer interface: describe your chronic pattern and your goal, see the branching logic, land on a suggested test with the reasoning attached. Framed clearly throughout as “the decision tree a doctor would likely follow, not a recommendation” — that’s a genuine content and UX constraint, not just a disclaimer, given how close this sits to medical advice.

Aimed at self-directed, proactive health users who already order their own lab panels and want to reason about it the way a doctor would, rather than guessing.
