High Accurate Strip Flu Rapid One Step Test Kits , Influenza Rapid Test Device
The Influenza A Rapid Test is an in vitro diagnostic test for the qualitative detection of influenza type A nucleoprotein antigens in nasopharyngeal swab and nasal aspirate samples, using the rapid immunochromatographic method. The identification is based on the monoclonal antibodies specific for the nucleoprotein of Influenza virus A. It will provide information for clinical doctors to prescribe correct
medications. Negative results should be confirmed by other methods, such as cell culture.
The Flu A+B Rapid Test Device is an in vitro diagnostic test for the qualitative detection of influenza A and B nucleoprotein antigens in nasopharyngeal (NP) swab, throat swab and nasal aspirate samples, using the rapid immunochromatographic method. The detection is based on the monoclonal antibodies specific for the nucleoprotein of either Influenza virus A or B. It is intended to aid in the rapid diagnosis of influenza A and B viral infection. Negative results should be confirmed by other methods, such as cell culture.
How to use?
Allow the test, specimen, extraction buffer to equilibrate to room temperature (15-30°C) prior to testing.
1. Remove the test dipstick from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the assay is performed immediately after opening the foil pouch.
2. Place the Extraction Tube in the workstation. Hold the extraction reagent bottle upside down vertically. Squeeze the bottle and let the solution drop into the extraction tube freely without touching the edge of the tube. Add 10 drops of solution (Approx. 400μl) to the Extraction Tube. See illustration 1.
3. Place the swab specimen in the Extraction Tube. Rotate the swab for approximately 10 seconds while pressing the head against the inside of the tube to release the antigen in the swab. See illustration 2.
4. Remove the swab while squeezing the swab head against the inside of the Extraction Tube as you remove it to expel as much liquid as possible from the swab. Discard the swab in accordance with your biohazard waste disposal protocol. See illustration 3.
5. With arrows pointing down, place the dipstick into the tube of solution and then start the timer. If the procedure is followed correctly, the liquid should be below the maximum line (MAX) on the test dipstick. See the illustration 4.
6. Wait for the colored line(s) to appear. Read the result at 15 minutes. Do not interpret the result after 20minutes.
INTERPRETATION OF RESULTS
(Please refer to the illustration above)
POSITIVE:* Two distinct colored lines appear. One colored line should be in the control region (C) and another colored line should be in the test region (T). A positive result in the test region indicates that Influenza A antigen was detected in the sample.
*NOTE: The intensity of the color in the test line region will vary based on the amount of Flu A antigen present in the sample. So any shade of color in the test region should be considered positive.
NEGATIVE: One colored line appears in the control region (C). No apparent colored line appears in the test line region.
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test dipstick. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
