Consideration should be given to the donor’s general state of health and ability
to tolerate a blood donation, as well as the possibility of intercurrent infection
that may affect the safety of the blood.
There are no reports suggesting increased adverse donor reactions in diabetic
donors. A systematic literature review found no studies investigating diabetes
as a possible risk factor for adverse reactions in voluntary blood donors; two
studies on pre-operative autologous donation and three experimental studies
found that blood donation was well tolerated (73).
Individuals with diabetes who require insulin should be permanently deferred from
blood donation (70) because of concerns regarding diabetes-related complications
and an increased risk of hepatitis and other infections if safe injection practices
cannot be assured.
Individuals with diabetes mellitus well-controlled by diet or oral hypoglycaemic
medication, provided they have no history of orthostatic hypotension and no
evidence of infection, neuropathy or vascular disease, in particular peripheral
