Evaluation and influencing factor analysis of the detection effect of hepatitis B virus surface antigen and treponema pallidum using rapid screening immunochromatography technology
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 10
Abstract
Objective To evaluate the effectiveness of rapid initial screening using HBsAg and syphilis reagents of immunochromatography technology before blood donation, and explore the influencing factors. Methods The pre-donation screening of HBsAg and anti-TP and post-donation blood test results of blood donors in Yangzhou region from January 2020 to June 2023 were retrospectively analyzed. The HBsAg and anti-TP reactive samples by ELISA from January to June 2023 were, retested using colloidal gold immunochromatographic reagents, and the results were compared and analyzed. Results A total of 200 414 blood donors were screened, among which 781 were HBsAg and anti-TP positive, accounting for 0.39%. A total of 191 717 blood donors successfully donated blood, and 986 were HBsAg and anti-TP positive by ELISA, accounting for 0.51%. 62 HBsAg and 61 anti-TP reactive samples were retested using the initial screening reagent, with 24 HBsAg reactive samples and 26 anti-TP reactive samples, accounting for 38.71% and 42.62% respectively. 14 HBsAg and 6 anti-TP gray area samples were retested, but no reactivity was found.The reactivity rates of 9 samples with HBsAg detection S/CO values greater than 25.0 and 10 samples with anti-TP detection S/CO values greater than 15.0 were all 100%.There was a negative correlation between the reaction intensity (S/CO value) of reactive samples and interpretation time of initial screening reaction. Conclusion The rapid primary screening of hepatitis B and syphilis with immunochromatography technology among blood donors can effectively improve the quality of blood and the qualification rate of blood after collection. Through targeted training of primary screening staff, the quality of primary screening can be further improved, the rate of missed detection can be reduced, and costs can be saved, thus reducing the risk of transfusion transmitted infection and ensuring the health of blood donors.
