A significant difference was found among groups with different blood donation types, Plasma donors had a relatively higher prevalence than whole blood donors of HCV infection (33.95% vs 7.9%).
Stratified analyses were performed by study locations, gender, age, study period, blood donor recruitment methods, type of blood donation, and blood type.
OneBlood, a Florida blood donation center, needs people with Type O-negative blood to donate.
21, 2018, in Washington, D.C. OneBlood, a Florida blood donation center, needs people with Type O-negative blood to donate.
To improve the comparability of the groups, seronegative subjects were matched to HTLV seropositive subjects by age (5 year groups), sex, race/ethnicity, type of blood donation (whole blood, autologous or platelet pheresis) and blood center.
The HTLV groups and seronegative participants were comparable with respect to age, sex, race or ethnicity, blood center visited, and type of blood donation (autologous versus allogeneic), except for slightly higher proportions of blacks among the HTLV-I group and Hispanics among the HTLV-II group.
Obviously, blood donation is different from other types of donation, such as monetary donation.
It could be years before this technology is in good enough shape to be used as an alternative to traditional blood donation, particularly for people with rare blood types.
Analyses were also done stratifying by tumor type (invasive and in situ), estrogen receptor status, age at enrollment, menopausal status at index date, lag time between blood donation and diagnosis of the case, and in the subgroup of women who had reported a history of regular menstrual cycles as well as five to seven cycles in the six months prior to blood donation.
Development of DNA-typing assays for antigen screening in blood donation qualification laboratories promises to enable blood banks to provide optimally matched donations.
