15 Clinical Evaluation Studies The performance of the SD BIOLINE Influenza antigen test was compared to cell culture or RT-PCR methods in a multi-center field clinical study. In this multi-center, a combination of nasal swabs and throat swabs specimens were collected from total 341 patients.*Test Period ;Oct.2003 ~ May 2005*Test Region ;Korea & OverseasVietnam (H5)HongKongThailand, etc
16 Clinical Evaluation Studies Summary of Clinical Evaluation Data
17 Clinical evaluation studies results performed at National Institute of Hygiene and Epidemiology, Vietnam (including H5 Human cases)*Test period : Dec.2004 ~ Dec.2005
18 SD BIOLINE Influenza Antigen test Competitiveness ofSD BIOLINE Influenza Antigen testWhy should you use “SD BIOLINE Influenza Antigen Rapid Test”?SD kit can cover all influenza virus type.SD kit can detect AIV infection in Human (A/H5N1).SD kit can differentiate influenza virus type A and BSD kit is very useful as POCT (point of care testing), on-site test.
19 SD BIOLINE Influenza H5 kit SD BIOLINE Influenza H5 rapid test isa chromatographic immunoassay for the qualitative detection of hemagglutinin H5 antigen of avian influenza (AI)virus directly from nasal swab/aspirate specimens,throat swab specimens,tracheal aspiratespecimens onAI virus human infectioncases.

21 specimen collection & preparation Nasal swabNasal aspirateThroat swabTracheal aspirate (Especially, test results with the tracheal aspirate specimens would be recommendable, because the majority of AIV may exist at the tracheal position.)
22 specimen collection & preparation If the specimen should be tested later, swab specimens should be placed into 1 ~ 2 ml of transport media or saline by direct extraction.Transport media : Use of the following transport media has been tested and found to be compatible with SD BIOLINE Influenza Antigen test.Saline EMEM+1%BSAPBS EMEM+0.5%BSAPBS+0.5%BSA Trypticase soy Broth+0.5%BSAPBS+0.5%Gelatin Trypticase soy Broth+0.5% gelatin
23 Special Precautionson Specimen collection & preparationUse of fresh sample is very important for getting accurate results.The specimen which have ever been thawed after freezing may results in decreased test sensitivity from the deterioration or modification of H5 antigen. So, repeated freezing and thawing of specimen must not be used for this test.Finally, to get accurate results, specimen should be tested as soon as possible after collection.
24 Test procedure & Interpretation ; nasal swab, throat swabTransfer assay diluent into test tube (approximately 300uL).Insert the patient swab sample into the test tube and mix well.Place the Test Strip into the test tube.Read result at 10 ~ 15 minutes.
25 Test procedure & Interpretation ; nasal aspirate, tracheal aspiratePipet 100uL of assay diluent and 100uL of aspirate specimen into test tube. And mix well.Place the Test Strip into the test tube.Read result at 10 ~ 15 minutes.
