Androgen Receptor (AR) Test - Immunohistochemistry: Androgen Receptor (AR)

A qualitative and quantitative immunohistochemical (IHC) assay using a monoclonal antibody against the androgen receptor (AR) aims to detect the presence and level of nuclear expression of the AR protein in tumor tissues. AR is a hormone-dependent transcription factor involved in the growth and proliferation of androgen-sensitive cells.
