Background A major complication of donation is vasovagal reaction (VVR) with/without syncope. VVR occurs not only in the early phase but also in late phase after donation. Some risk factors have been reported but they have not satisfactorily predicted late VVR. Methods and Results After blood collection, 97 healthy donors were kept standing for 3minutes while blood pressure (BP) and heart rate (HR) were recorded. Questionnaires were returned from them to report late VVR during 24 hrs after donation. HR of donors with late VVR increased significantly compared with donors with no symptoms (Figure A). Area under the ROC curve about the HR after 2 minutes is 0.8 (Figure B). Conclusion HR response to standing after blood collection may satisfactorily detect the high‐risk donors prone to late VVR.
