1.   INTENDED USE

Canine Distemper Virus Ag Test is a sandwich lateral flow immunochromatographic assay for the qualitative detection of canine Distemper virus (CDV Ag) in dog’s secretions or serum.

Assay Time:  5 - 10 min

Sample: Secretions or serum

2.     PRINCIPLE OF THE ASSAY

Canine Distemper Virus Ag Test is based on sandwich lateral flow immunochromatographic assay. The test device has a testing window. The testing window has an invisible T (test) zone and C (control) zone. When sample is applied into the sample hole on the device, the liquid will laterally flow on the surface of the test strip. If there is enough Distemper antigen in the sample, a visible T band will appear. The C band should always appear after a sample is applied, indicating a valid result. By this means, the device can accurately indicate the presence of Canine Distemper antigen in the sample.

3.     KIT COMPONENT

-       10×foil pouches, each containing a cassette, pipette and desiccant

-       10×assay buffer tubes (0.7 mL each) 

-       10×swab sticks

-       Product Manual

4.     TEST PROCEDUR

-       Collect dog’s ocular and nasopharyngeal secretions with the swab stick. Make the swab wet sufficiently.

-       Insert the wet swab into the provided assay buffer tube. Agitate it to assure good sample extraction.

-       If using serum sample, please do a dilution of 1:2 with the provided assay buffer. 

-       Take out the cassette from the foil pouch and place it horizontally.

-       Gradually drip 3 drops of sample extraction into the sample hole.

-       Interpret the result in 5 - 10 minutes. Result after 10 minutes is only considered as reference.

5.INTERPRETATION OF RESULTS

Positive: The presence of both C band and T band, no matter T band is clear or vague.

Negative: Only clear C band appears.

Invalid: No colored band appears in C zone, no matter whether T band appears.
