Canine influenza (known as dog flu) is a contagious respiratory disease (e.g., pneumonia) in dogs caused by specific Type A influenza viruses. The symptoms of this disease in dogs are cough, runny nose, eye discharge, fever, lethargy, and reduced appetite, but not all dogs will show signs of illness. As the canine influenza virus (CIV) is rapidly transmitted between dogs, immediate diagnosis is essential.
The RIDX^® CIV Ag Test Kit is a lateral flow chromatographic immunoassay for the qualitative detection of canine influenza virus antigens in canine pharyngeal or nasal secretions. This kit shows two letters which are the test (T) line and the control (C) line on the surface of the device. If the CIV antigen exists in the sample, it binds to the cellulose nanobeads (CNB)-conjugated CIV antibody. The antigen-antibody complex moves through the membrane by capillary force and responds to the CIV antibody on the test line, resulting in a red line. The control line indicates that the test is performed correctly and should appear when the test is complete.
The highly selective and sensitive two monoclonal antibodies to CIV are used as capture and detector in the kit. The RIDX^® CIV Ag Test Kit can detect CIV antigens in canine nasal or pharyngeal secretions with high accuracy.

1. All reagents and samples must be at room temperature (15~30℃/59~86℉) before use.
2. Collect nasal and pharyngeal samples using a swab.
3. Put the swab into the sample dilution buffer and stir the solution with the swab to disperse the sample into the buffer (approximately 10 seconds).
4. Remove the swab from the sample dilution buffer.
5. Wait for 20 seconds to settle down the large particles.
6. Remove the test device from the pouch and place it on a flat and dry surface.
7. Take the supernatant sample in the tube by using a disposable dropper.
8. Add 4 drops of the mixed sample into the sample hole (S), drop by drop vertically.
9. Read test results at 10 minutes.
