Notes: aTypes of donors were considered not reported if they did not characterize patients into replacement donors, paid donors, or voluntary non-remunerated donors. bTotal frequency for a single TTI was calculated based on the total number of donors positive for that TTI such as HIV, syphilis, or malaria divided by the total number of donors screened for that TTI multiplied by 100.
Abbreviations: ELISA, enzyme-linked immunosorbent assay; KPK, Khyber Pakhtunkhwa; NAAT, nucleic acid amplification test; RD, replacement donors; NR, not reported; VNRDs, voluntary non-remunerated donors.
