Total Estrogens, RIA, 100 tests
In the ImmuChemTM Total Estrogens assay, the reaction follows the Mass Action Law and the labeled and non-labeled analytes bind to the antibody in proportion to their relative concentrations.
The amount of radioactive analyte which binds is inversely proportional to the amount of unlabeled analyte in the sample. When cmpared to a series of calibrators, a dose response curve can be constructed which plots the counts bound versus the dose of the analyte.
Because of the inverse relationship between the dose of the analyte and the counts bound, counts bound will decrease with increasing concentration of nonlabeled analyte as shown in the sample standard curve.
