ABSTRACT
BACKGROUND:
We report here the results of surveys for external quality assessment of blood bank tests performed in 2009.METHODS:
Survey specimens were sent three times to 488, 491 and 490 participant institutes, and the response rates for the 1st, 2nd and 3rd trial were 97.7%, 98.0%, and 98.0%, respectively. Test items for the surveys were ABO grouping, Rh (D) typing, crossmatching, direct antiglobulin test, antibody screening and antibody identification test.RESULTS:
The average accuracy rates of ABO grouping and Rh typing were 99.6-100% and 98.5-100%, respectively. In crossmatching test, the accuracy rates were 99.3-99.8% for the compatible samples, 92.7-100% for the incompatible samples, and 92.6-93.1% for the samples which could be detected as incompatible only by antiglobulin method. The accuracy rates of direct antiglobulin test were 98.5-100% for negative samples and 98.1-98.8% for positive samples. The correctresults were reported by 98.0-100% of the surveyed institutions for antibody screening test and 82.9-100% for antibody identification test. Nineteen institutions gave repeatedly incorrect answers for crossmatching test. Eight institutions out of them gave incorrect answers for all the test specimens sent out 3 times last year.CONCLUSIONS:
The overall results of this survey were good, however, it is required that the institutions where the incorrect results were reported should perform corrective actions for quality improvement.
