Principle

LH iClia is chemiluminescent immunoassay based on the “Sandwich” principle. The magnetic microspheres are coated with Anti-LH antibodies.

The samples are added in the assay cup containing Assay Buffer and anti-LH antibodies coated microspheres followed by addition of AE conjugate (Anti-LH antibodies linked to acridinium ester) to assay cup . A sandwich complex is formed wherein LH (from serum sample) is “trapped” or “sandwiched” between the microspheres coated antibody and antibody labelled with AE conjugate. Unbound conjugate is then washed off with wash buffer. The amount of bound AE conjugate is proportional to the concentration of LH present in the sample. Finally pre-trigger and trigger solution containing hydrogen peroxide and sodium hydroxide solution is added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative Light units (RLUs). There is a direct relationship between the amount of LH present in the sample and the RLUs detected by the optical system. Results are calculated automatically based on the established calibration curve.
