ABSTRACT:
The present invention discloses novel immunogens, antibodies prepared from such immunogens, and labeled reagents useful in immunoassays for the detection and quantification of testosterone in a test sample. Also disclosed are immunoassays using these reagents and methods for synthesizing these reagents. The immunoassays are preferably microparticle enzyme immunoassays (MEIAs) and fluorescence polarization immunoassays (FPIAs). Further disclosed are novel starting materials for making the above novel immunogens and labeled reagents. Methods for making the novel immunogens and labeled reagents from the novel starting materials are also disclosed.
