Abstract

|
|
The purpose of this study is to provide some basic date useful to standardize the blood tests and enhance the safety of blood transfusion. For this purpose, 36,410 patients were sampled (who visited a university hospital in Seoul for transfusion or operation from July 1, 1990 to June 30, 1995) and thereupon, the results of their antibody screening tests were analyzed to identify the types of the antibodies.
Meanwhile, in order to survey the method of pre-transfusion serologic tests as well as the social medical environment, 32 third medical institutions were selected to be categorized into two groups : those who perform the tests and those who do not. Lastly, the blood bank chief technologists of this final sample were surveyed again by means of questionnaires from March 1, 1996 to April 20, 1996, The collected data were statistically analyzed using the SPSS program for frequency, percentage, means, t-test, Pearson’s correlation coefficient and discriminant analysis. The results of this study can be summarized as follows;
First 168 cases or 0.46% out of36,410 antibody screening tests were found to have unexpected antibodies.
Second, the antibodies which belong to Lewis family accounted for 27.9% of the unexpected cases, followed by usual cold antibodies (20.8%), Rh-family ones (10.1%).
Third, the variables affecting most of the antibody screening tests were blood bank chief technologists’ burden of detecting warm antibodies, the number of the special medical technologists working for blood bank and routine cross matching phases.
