The One Step Test for NT-proBNP (colloidal gold) is intended for use together with the FIA8000 Quantitative Immunoassay Analyzer (FIA8000). The product employs colloidal gold immunochromatogrphy to determine NT-proBNP in human serum, plasma, or whole blood specimens. One monoclonal antibody and one polyclonal antibody are employed to identify NT-proBNP specifically, resulting in a purplish red streak appears on the test line. The color intensity of the test line increases in proportion to the concentrations of NT-proBNP.

Then insert test card into the FIA8000 Quantitative Immunoassay Analyzer, the concentration of NT-proBNP is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.
