Bga and Bgb Correlations with HLA Antigens by Capillary Tube Technique

Abstract
The manual capillary tube technique, in 114 blood samples collected into CPD [citrate-phosphate-dextrose] demonstrated Bga on the red blood cells of 93% of the HLA-B7 donors, and Bgb on the red blood cells of 80% of the HLA-B17 donors. These results compare favorably with reported autoanalyzer studies. Successful results require normal red blood cell-plasma ratios in the samples and avoidance of heparin for collection.
