Canine Adenovirus Ag Test is a sandwich lateral flow immunochromatographic assay for the qualitative detection of canine Adenovirus (CAV Ag) in dog's secretions or serum.. Assay Time: 5 - 10 min Sample: Secretions or serum Canine Adenovirus 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 Adenovirus-II 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 Adenovirus-II antigen in the sample.
