Abstract

Sex steroid measurements for the investigation of endocrine disorders have been fraught with accuracy and imprecision problems since the advent of high throughput, direct assays almost 10 years ago on automated analyzers. Results from testosterone and estradiol measurements at the low end of detectability have suffered the most and there are few automated systems that can accurately measure these steroids in women, children and hypogonadal males on a routine basis. With the advent of mass spectrometry coupled to either gas chromatography or liquid chromatography, an improved approach to the measurement of these steroids has developed that shows promise for accurately and precisely measuring testosterone and estradiol in all patient populations including women and children. These mass spectrometry based methods for the sex steroids have been established as higher order reference method procedures that will resolve the issues of low end sensitivity measurements for these steroids, provide for appropriate standardization and reference materials and align most laboratories in hospital and reference laboratories to generate results that are inter-changeable between laboratories and methods.
