Abstract
A totally revised crossmatching and antibody screening procedure was designed using low ionic strength saline as the suspending medium for [human] red cells in the saline and enzyme phases as well as the antiglobulin test. The replacement of Pasteur pipettes with precision samplers for all serum and red cell dispensing resulted in improvement in the reproducibility and standardization of technique. The major advantages are improved sensitivity, shortened incubation time and simplicity of technical performance.
