The Frequency and Distribution of Unexpected Antibodies in Surgical Patients at Chonbuk National University Hospital / 대한진단검사의학회지

ABSTRACT

BACKGROUND: Unexpected antibody screening and identification tests using a column agglutination method are very important in elective surgical patients. We compared the frequency and distribution of unexpected antibodies in our elective surgical patients with other results. METHODS: We analyzed the results from 6, 500 antibody screening tests performed for elective surgical patients at Chonbuk National University Hospital during the recent five-year period. Screening and identification of unexpected antibodies were carried out using a column agglutination method with the DiaMed-ID system (DiaMed, Cressier, Morat, Switzerland). RESULTS: Unexpected antibodies were detected from 42 samples (0.64%) out of all 6, 500 samples. Clinically significant antibodies were found in 0.32% of all the population. Of these, 13 samples showed anti-E, 3 samples showed anti-E+c, 3 samples showed anti-D, 1 sample showed anti-Fyb and another one sample showed anti-Kpa. CONCLUSION: The results of frequency and distribution of unexpected antibodies in Chonbuk National University Hospital were not different from others. We have verified that the antibody screening and identification test using the column agglutination technique would have had a higher detection rate for clinically relevant antibodies such as anti-Rh antibodies than other methods.
