Abstract
|
|
|
Background: The demand for Rh-related and other specific antigen negative donations has increased recently, and in response, we need to improve work efficiency while decreasing reagent consumption. Thus, we desire to create a ‘table of Nambu Blood Laboratory Center’s own Rh-related and other antigen negative rate’.
Methods: We analyzed the results of Rh-related specific antigen test for 2,806,330 donors using ‘PK-7300’ and the results of manual test for 10,024 other blood type antigen-related specific and compound antigens. We made a table summarizing the results using two cases.
Results: The negative rate of Rh-related specific antigens was approximately 12.9% for C, 41.7% for c, 49.5% for E, and 9.2% for e antigens. The negative rate of compound antigens was increased when compared with the number of inspections. The negative rate for C and e antigens was increased from 90.1% to 97.3%, and that for E, c, and JKa was increased from 7.6% to 31.6%.
Conclusion: The negative rate table made in July 2016 has been determined to be very effective in screening for specific and compound antigen negative blood. Also it was very efficient in terms of examining and supplying the compound antigen negative blood. It would be helpful to improve the supply of specific antigen negative blood to better meet the unique needs of each medical institution.
