Bga and Bgb correlations with HLA antigens by capillary tube technique

The manual capillary tube technique, in a series of 114 blood samples collected into CPD, demonstrated Bga on the red blood cells of 93 per cent of the HLA-B7 donors, and Bgb on the red blood of 80 per cent 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.
