Abstract
The invention relates to low wash Thyroid Stimulating Hormone (TSH) immunoassays using an ELISA sandwich assay having limited or no wash step between the antigen capture, detection antibody addition and substrate introduction steps. This invention exhibits low cross reactivity with biologically similar interfering cross reacting species, such as Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) and Chorionic Gonadotropin (CG).
