The One Step Test for mAlb (colloidal gold) is intended for use together with the FIA8000 Quantitative Immunoassay Analyzer (FIA8000). The product employs colloidal gold immunochromatogrphy to determine mAlb in human urine specimen. Polyclonal antibody and recombinant antigen are employed to identify mAlb 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 mAlb. Then insert test card into the FIA8000 Quantitative Immunoassay Analyzer, the concentration of mAlb is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.
