Abstract
Background: Asia accounts for 59·7% of the global population. Securing an adequate blood supply in the region relies on accurate knowledge of Asian blood donors, and donation practices, but the majority of published evidence is based on non-Asian populations. To address this knowledge gap this study aims to gather accurate, and current data on blood donors, and donation practices in Asia.
Methods: Ten blood collection agencies (BCAs) (six national, and four regional) provided 12 months of data on donors who met eligibility criteria, or were deferred, and details on their donation practices. Body mass index, and blood volumes were calculated, and data was analysed in R version 4·0·3 (2020-10-10).
Findings: Analysis of data on 9,599,613 donations, and 154,834 deferrals, revealed that ABO, and RhD blood group frequencies transitioned when BCAs were arranged based on longitudinal locations. Donation eligibility, and blood collection practice varied. Seven BCAs had minimum haemoglobin levels below the WHO anaemia threshold, and seven accepted donors with weight <50kg. Deferred donors appear to weigh less than those who donated, with corresponding lower estimated blood volumes.
Interpretation: The diversity in donor eligibility criteria, and donation practices reflects each BCA’s unique strategy for balancing donor health, and securing blood supply. Data on donor weight, and height should be collected to objectively define local donation criteria. There is a need for BV estimation formulae specifically for the Asian phenotype. Information from this study may be used to develop donation criteria of Asian donors in non-Asian regions.
