Flow cytometry: a tool in immunohematology for D+W (Du) antigen evaluation?

abstract：BACKGROUND AND OBJECTIVES:Weak ABO variants may escape tests using unlicensed sera. MATERIALS AND METHODS:Prior to transfusion, ABO grouping was performed using an automated system and in-house diluted sera, and manual and bedside test techniques. Genotyping and sequencing were performed using standard methods. RESUL...
