To reduce the risk of transfusion related complications, blood components should, according to European guidelines, contain less than 1 x 106 leukocytes per unit. To verify that these guidelines are upheld, residual leukocytes are measured in randomly selected blood components as means of quality control. At Uppsala University Hospital, the method currently used for this is flow cytometry (FCM). However, the hospital recently purchased a new instrument, ADAM rWBC2, for this purpose. The aim of this study was to verify ADAM rWBC2 as a replacement method for FCM and investigate whether the type of test tube chosen for the instrument (EDTA or micro test tube) would affect the leukocyte concentration. To conduct the study, 30 red blood cell units (RBCs), 30 platelet units (PLTs) and 30 plasma units were analyzed on both the ADAM rWBC2 instrument and with FCM. In addition to this, each RBC and PLT unit was allocated into both an EDTA tube and a micro test tube before analysis on the ADAM rWBC2 instrument. Results from both methods and tubes were compared using statistical analysis. The results from ADAM rWBC2 tended to be higher than the results from FCM, and the difference turned out to be statistically significant (p<0,001). No significant difference could be detected between the results from the different test tubes. The assessment is that ADAM rWBC2 will replace FCM for quality control of residual leukocytes in blood components. According to the results, the type of test tube used does not affect the leukocyte concentration.
