According to the colloidal gold immunochromatographic test principle, the test line (T) and the control line (C) are immobilized on the nitrocellulose membrane with test line (T) coated with rheumatoid factor antigen and control line (C) coated with mouse anti-goat IgG, Colloidal gold conjugate pad is labeled with rheumatoid factor antigen and goat IgG. When the concentration of RF is equal to or higher than the
limit of detection, it binds to the gold labeled rheumatoid factor antigen to form a complex. The complex moves forward under the action of chromatography and combines with rheumatoid factor antigen on the test line (T) to develop a colored line, which indicates a positive result. When the concentration of RF is below the limit of detection, no complex can be formed on the test line (T) and no colored
line appears, which indicates a negative result. No matter whether the samples contain RF or not, a colored line will always appear
in the control line (C) region if the test has been performed properly.
