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.

Reagents and methods for the detection and quantification of

The present invention discloses a process for making 1-.alpha.-(carboxyalkyl)testosterone having the following formula: ##STR1## The process involves protecting the 17 position of 1,4-androstadien-17 .beta.-ol-3-one with TBDMS, alkylating with an alkenylmagnesium bromide and ozonolyzing the resulting ether. The resulting product is oxidized with sodium hypochloride followed by removal of the TBDMS protecting group with aqueous hydrofluoric acid in acetonitrile to produce the 1-.alpha.-(carboxyalkyl)-testosterone.
