Gastrointestinal mucosal stress bleeding caused by alimentary tract hemorrhage or other diseases can lead to positive fecal occult blood (FOB). Active inflammation of the intestinal mucosa results in elevated calprotectin (Cal) levels.
Multiple pathogens-including Giardia (GIA), Helicobacter pylori (HP), Campylobacter jejuni (C. jejuni), Helicobacter pylori-CagA (HP-CagA), Canine parvovirus (CPV), Canine Coronavirus (CCV) and Canine rotavirus (CRV) are all common causative agents of canine diarrhea. Multiplex testing for these indicators helps identify the underlying cause and facilitate targeted treatment.
This product utilizes fluorescence immunochromatography to quantitatively detect the content of FOB/Cal/HP-CagA/CPV/CCV/CRV/GIA/HP/C.Jejuni Ag in dog’s feces. The basic principle is as follows: T and C lines are respectively marked on the nitrocellulose membrane. The T line is coated with an antibody a that specifically recognizes the antigen. The binding pad is sprayed with another fluorescent nano-material-labeled antibody b that specifically recognizes antigen. The antigen in the sample first combines with the nano-material-labeled antibody b to form a complex. Then, through chromatography, the complex moves upward to bind to T line antibody a, forming a sandwich structure. When the test strip is irradiated by excitation light, the nanomaterial emits a fluorescent signal, and the intensity of this signal is correlated with the concentration of antigen in the sample.
