Caregivers' attitudes toward blood-based biomarker testing for Alzheimer's disease.

Introduction: We aimed to evaluate informal caregivers' attitudes toward undergoing and future implementation of blood-based biomarkers (BBBM) testing for Alzheimer's disease (AD).

Methods: We explored caregivers' perspectives, by combining an online survey ( = 107) with a subsequent focus group ( = 7). We used descriptive statistics and thematic content analysis to identify common themes in answers to open-ended survey questions and focus group data.
