Abstract

Background
According to blood management law, serology and nucleic acid testing (NAT) are performed for HIV, HBV, HCV, and others as blood screening tests in Korea. The blood screening tests for HIV, HBV, and HCV have substantially improved transfusion safety. The blood screening results of one blood center were investigated because there is little domestic data available on screening tests.
Methods
The blood donation records and screening tests results of a supplying blood center were analyzed retrospectively from January 2011 to December 2020 in Korea. Annual first-time donation numbers, sex, and age distribution of donors were investigated during 10 years. The positivity of ALT, HBsAg, anti-HCV, and anti-HIV antibody testing and the positive cases of HIV, HCV, and HBV NAT were inquired.
Results
For 10 years, the blood center has collected 1,896,392 units of blood, and male donation was 1,239,873 units, which was 65.38% of total blood donation. ALT abnormal blood units were 2.06% in 2011, 2.14% in 2013, and 0.81% in 2019. The donor screening test showed HBsAg 0.03%, anti-HCV 0.02%, and anti-HIV 0.06% positivity at 2020. NAT yield cases were three with HIV, two with HCV, and 260 with HBV for 10 years.
Conclusion
The positivity of serology screening tests of the Hanmaeum blood center showed a decreasing trend, and the transfusion of nucleic acid positive but serologically negative blood could be prevented by performing NAT.
