NR= nonreactive

RE= reactive; ‘-’= not tested; D= donation; NEG= negative; Pos= positive; IND= indeterminate, N.B: All repeat donors reactive in single kit were negative for NAT and RIBA. They were reactive by a particular kit in the present donation but non-reactive by other kits in previous donations.
