LEVEL OF AGREEMENT OF THE HBsAg TEST IS EQUAL RAPID AND AUTOMATIC IMMUNOLOGY TEST METHOD IN SCREENING FOR HEPATITIS B VIRUS

Tóm tắt

Objectives: The study aims to evaluate the level of consensus of HBsAg screening test using rapid test and automated immune testing methods in hepatitis B screening at Lao Cai Provincial General Hospital from May, 2024 to - June, 2024.
Methods: Cross-sectional descriptive study.
Results and conclusions: The study included 980 patients screened for HBsAg using rapid test and automatic immune testing from May, 2024 to June, 2024. The similarity between the two rapid and immunological test methods has Kappa = 0.92, almost complete agreement. The sensitivity of the rapid test is 98.9%, the specificity of the rapid test is 98.5% when considering the immunological method as the gold standard, the rate of HBsAg(+) screening results is > 70 COI screened by the method. Autoimmunity is 10.1%. The age group with the highest incidence is from (30 - 50 years old) accounting for 13%. The proportion of men is 11%, women is 8.5%, Patients residing in rural areas account for a higher rate of 12.2%, and 7.3% in urban areas with P < 0.05. The Tay ethnic group accounts for the highest proportion at 14.5%. There are 2.4% of HBsAg screening cases with indeterminate results (1 - 70 COI). The rate of HBsAg(+) carrier is 10.1%. The similarity between the two rapid and immunological test methods has Kappa = 0.92, almost complete agreement. The sensitivity of the rapid test is 98.9%, the specificity of the rapid test is 98.5%.
