Some factors affecting the sensitivity of the automated methods for blood group antibody detection have been evaluated. The experiments revealed influencing differences between various albumin preparations. In the BMC method, one lot of albumin permitted no significant antibody detection. In the LISP technique, a plateau of maximum Polybrene activity was found. The beginning of this plateau depended on both the albumin preparation and the Polybrene lot. In the BMC method, methyl cellulose gave optimal sensitivity within a concentration range of 0.3 to 0.5 per cent. The stability of test cells stored in ACD at 4 C was studied. All test cells could be used safely up to two weeks. Cells from different donors showed variable reactivity after three weeks.
