Canine Heartworm Ag Rapid Test is a sandwich lateral flow immunochromatographic assay for the qualitative detection of Dirofilaria immitis (CHW Ag) in dog' s blood, serum or plasma. Assay Time: 5 -10 min Sample: Serum, plasma or blood Canine Heartworm Ag Rapid 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 a 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 CHW 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 Dirofilaria immitis antigen in the sample.
