초록

본 논문은 국내 인플루엔자 신속항원검사키트의 민감도의 검출한계를 분석하기위하여 국내 시판중인 인플루엔자 신속항원검사키트 5종을 대상으로 인플루엔자 바이러스 A형과 B형 배양액을 연속 희석하여 양성 검출 한계를 분석하였다. 분석 결과 A형의 육안측정결과는 웰스바이오 제품은 1:8192까지, II제품은 1:4096까지, I과 III제품은 1:512까지, IV제품은 1:128에서만 양성이 확인되었고, B형 육안측정결과는 웰스바이오 제품이 1:8192까지, II제품은 1:4096까지, I, III, IV제품의 경우 1:1024까지 양성이 확인되었다. 같은 검체의 기기 판독의 경우 A형, B형 모두 웰스바이오 제품이 1:8192까지, II제품이 1:4096까지, I제품은 1:2048까지 양성으로 확인되었다. 인플루엔자 신속항원검사의 민감도는 환자의 검체 채취부위 및 감염기간, 검체의 양 등에 따라 많은 차이가 있으므로, 검체의 채취시기 및 방법 등을 정확하게 준수해야할 것이며, 신속항원검사 키트의 민감도를 높이기 위한 다각적인 연구가 필요할 것으로 사료된다.

In this study, to analyze the detection of limit for sensitivity of the influenza rapid antigen test kit, the positive detection of limits were analyzed by serial dilution of influenza virus A and B type for five influenza rapid antigen test kits in Korea. As a result of analysis, visual measurement of type A were up to 1:8192 for the Wellsbio product and up to 1:4096 for the II product, up to 1:512 for the I and III products, and only 1:128 for the IV product, and type B were positive for up to 1:8192 for the Wellsbio product, up to 1: 4096 for the II product and up to 1:1024 for the I, III and IV products. For instrument readings with the same specimen, both A and B types were found to be positive for up to 1:8192 for the Wellsbio product, up to 1: 4096 for the II product, and up to 1:2048 for the I product. The sensitivity of the rapid antigen test for influenza differs greatly depending on the sampling area of the patient, infection period, specimen volume, etc. Therefore, it is necessary to observe exactly the collection timing and method of the specimen. And it is necessary further study to improve the sensitivity for influenza rapid antigen test.
