Principle (Antigen-Antibody Reaction)

Vitamin D Quanti Card is based on principle of competitive immunoassay. The vitamin D from the sample is first released/extracted. The assay is based on competition between extracted vitamin D from test sample and vitamin D biotin conjugate for the limited no of binding sites of specfific antibodies fluorochrome conjugate. As a result higher concentration of vitamin D produces a lower fluorescence signal and vice versa. The signal is interpreted and displayed on device reader in form of results.
