Use of modified automated polybrene test for screening IgG sensitized RBC in routine laboratory

An automatic method for the screening of RBC sensitized by IgG, using the polybrene reagent was utilized. We compared data drawn from the analysis of the automatic routine test in 4799 patients with the results obtained by the direct anti-IgG antiglobulin test. We give evidence for the highest sensitivity of the polybrene test with a good overlap of the results of two methods.
