title: A survey about blood bank policies and procedures.
abstract: A questionnaire about blood bank policies and procedures was prepared and sent out to 170 hospitals across the nation, 50 per cent responded. There is wide variation in both technical and nontechnical policies and procedures. Serum is separated from the original tube within 8 hours by 68 per cent of the hospitals and in 32 per cent serum is never separated from the original tube. Auto-control is included by 66 per cent of hospitals in at least one phase of the antibody testing, 34 per cent do not include auto-control in any phase. Du testing of the recipient is done in 85 per cent of the hospitals and in 15 per cent Rho type is determined by the immediate spin reactions alone. Slide type is the only method used to determine ABO group of cells of the recipients in 10 per cent of the hospitals, 18 per cent use serum-cell suspension, 10 per cent use the applicator stick method and only 62 per cent use washed saline-cell suspension routinely. Compatiblity testing between a recipient and a donor vary from a one-tube major crossmatch to a three-tube major crossmatch and minor crossmatch.
