AFP test Alpha-fetoporotein quantitative test kit adopts highly specific antigen-antibody reaction and colloidal gold immune chromatography to detect AFP. In a specific wavelength. the amount of colloidal gold particles is associated with the absorption and scattering to light. By using the photoelectric sensor to detect the absorption and scattering of colloidal gold particles to the light . the amount of antigen to be determined can be obtained.
