title: The measurement of androgens.
abstract: A number of androgens are measured for clinical purposes. Most laboratories will run a testosterone assay but the requirement for other androgens may be too small for a laboratory to set up their own assay. In these cases samples would be sent to a specialized laboratory. In the routine laboratory testosterone is analyzed on automated systems but these lack the sensitivity to accurately measure the hormone in children and normal women. Many laboratories analyzed such samples by radioimmunoassay, but tandem mass spectrometry is now replacing these assays. This chapter provides simple methods for measuring the androgens in serum and saliva by radioimmunoassay and tandem mass spectrometry.
