SD BIOLINE Influenza Antigen test
Competitiveness of SD BIOLINE Influenza Antigen test Why 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 B SD 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 is a 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 aspirate specimens on AI virus human infection cases.

Test Principle & Major active ingredient - Detection by Direct Sandwich System mouse monoclonal anti-influenza H5-gold conjugate Gold Gold Flu H5 Ag in specimen mouse monoclonal anti-influenza H5 C line T line (Influenza A/H5) Target materials : Hemagglutinin H5 antigen of avian influenza (AI) virus in respiratory specimen
21
specimen collection & preparation
Nasal swab Nasal aspirate Throat swab Tracheal 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%BSA PBS EMEM+0.5%BSA PBS+0.5%BSA Trypticase soy Broth+0.5%BSA PBS+0.5%Gelatin Trypticase soy Broth+0.5% gelatin
23
Special Precautions on Specimen collection & preparation Use 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 swab Transfer 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 aspirate Pipet 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.

Applications of Influenza Rapid kits
on Avian Influenza diagnosis programs Respiratory specimen RAT by SD BIOLINE Influenza Ag test In case of emergency that happen to outbreak of AI in the poultry, SD BIOLINE Influenza H5 test should be used directly. Type A positive Type B positive RAT by SD BIOLINE Influenza H5 test Treatment or Confirm test by RT-PCR/viral culture H5 positive negative Send Samples to Reference Laboratory that participates in WHO/CDC programs for flu/H5 surveillance, immediately Negative **WHO recommendations on the use of rapid testing for influenza diagnosis ; Influenza surveillance should be used to guide the optimal use of RAT (rapid antigen test). At the beginning of the influenza season or an influenza outbreak, RAT may influence on clinical decisions and contribute to clinical awareness.

Advantages as an aid of H5 diagnosis
SD BIOLINE Influenza H5 Advantages as an aid of H5 diagnosis For the screening test, the Sole H5 Avian Influenza Antigen Rapid Kit in the world Accurate detection on H5N1 samples isolated from Human infection cases, with High Sensitivity and Specificity With same kits, we’ve got lots of AI positive cases through HPAI (H5N1~H5N9) detection in the farm, market, or laboratory by use of feces or cloacal swab as veterinary use. Easy assay procedure: No technical expert and No equipment is required Labor & Time saving because of fast results
