Patient Information
Demographics calibrate the PALM-COEIN differential and age-stratify labs, imaging, and management.
AUB Pattern Selection (FIGO 2018)
Select all patterns that apply — patients frequently present with more than one simultaneously. The workup merges all selected patterns into a single unified PALM-COEIN differential.
