What this app does NOT do

No condition naming — this app never names a condition.
No treatment advice — it never tells you what medicine to take, change, or stop.
No emergency guidance — if you feel seriously unwell, seek urgent care or call your local emergency number.
No replacement for your doctor — lab values are one piece of a much bigger picture only a clinician can put together.
