Negative reactions when giving blood are extremely rare and usually not complicated, according to data compiled in the AABB Donor Hemovigilance report for 2012-17.
In 2017, just 2% of blood donors reported having some sort of a reaction during or following donations, said the report by the sanctioning organization for blood centers. Of those reactions, more than half were “prefainting,” a term for dizziness or light-headedness.
Dr. Rachel Beddard, Chief Medical Officer at BioBridge Global, said the results of the survey were not surprising. From educating donors about preparation, to asking specific questions before donation, to training of staff, the process is designed to make the process as painless as possible.
