Principle

Vitamin D iClia is chemiluminescent immunoassay based on the “competitive” principle.

The magnetic microparticles are coated with anti-25 OH vitamin D antibodies. The assay diluent, anti-25 OH vitamin D antibodies coated magnetic microparticles and samples are mixed. After incubation, vitamin D AE conjugate is added to reaction mixture. During incubation 25 OH vitamin D of sample compete with 25 OH vitamin D AE conjugate for binding of anti-25 OH vitamin D antibodies coated on magnetic microparticles. After further incubation and washing, Pre-Trigger and Trigger Solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative Light units (RLUs). There is an indirect relationship between the amount of Vitamin D present in the sample and the RLUs detected by the optical system. Results are calculated automatically based on the established calibration curve.
