Doximity launched DoseCheck, a rule based check that tests every dosing claim in a Doximity Ask answer against a structured drug database built from FDA labeling and professional guidelines, instead of asking a model to grade itself. In Doximity's test of nine widely used AI models on more than 8,000 real physician dosing questions, at least 2.3 percent of dosing claims were wrong and 43.8 percent of those errors were serious or potentially lethal. DoseCheck is free and live for all Ask users on mobile and desktop.
Our readDosing is where a confident wrong answer does the most harm, and a deterministic check against labeling is a stronger guard than a second model. Doximity says it lifts dosing accuracy above 99 percent; the testing is its own and has not been published.
