Background Whole blood donors may experience post‐donation symptoms such as fatigue, dizziness, or headache after blood donation, which could influence donor retention. We aimed to examine post‐donation symptoms during 1 week after whole blood donation, investigate donor characteristics associated with symptoms, and evaluate associations between symptoms and donor return. Methods During 1 week, whole blood donors who donated successfully at one of the collection centers in The Netherlands were invited to participate. Three thousand seventy six donors filled in a diary, assessing post‐donation symptoms during days 1 to 6 after donation. We used linear mixed models analyses to determine the change in post‐donation symptoms after donation for male and female donors separately. Furthermore, we investigated associations between post‐donation symptoms and donors' physical characteristics using multivariable regression and determined associations between symptoms and donor return. Results Donors reported fatigue as the most common symptom, with approximately 3% of donors experiencing severe problems at the first day after donation. Multiple symptoms improved significantly up to day 3 after whole blood donation. Age, BMI, blood pressure (male donors), and blood volume (female donors) were significantly associated with post‐donation symptoms. Donors with less fatigue after whole blood donation were more likely to return for their next donation within 31 days after receiving an invitation. Conclusion Post‐symptoms improve up to 3 days after whole blood donation. Our results may help blood collection centers to identify donors more prone to post‐donation symptoms and provide personalized information about the presence and course of post‐donation symptoms, possibly increasing donor return rates.
