Objective To identify antibody specificity in an elderly patient with hydronephrosis accompanied by ureter-al stones and shock who had multiple antibodies.Methods Microcolumn gel method was used to screen unexpected anti-bodies of red blood cells and identify antibodies.Enzyme method and antibody absorption method were used to help judge the specificity of antibodies in patients.The ABO blood type,Rh blood type and MNS blood type of patient were determined by saline tube method.Results The patient′s blood types were O,CCDee,NNss,and a combination of anti-E,anti-c,anti-M and anti-S antibodies was detected.Conclusion Repeated blood transfusion may lead to the presence of one or more un-expected antibodies in patients.Patients with multiple or high-frequency antibodies may experience difficulties in identifica-tion and delayed blood use.
