Using GC-MS/MS for Superior Sensitivity, Specificity and Precision in Free Testosterone Analysis - Rohan A. Thakur, Clark Williard and Agnita Rajasekaran
This article discusses biologically important steroid measurements which have, in the past, seen a lack of analytical sensitivity. Examples include determination of testosterone levels in women and children and estrogen levels in post-menopausal women. The article gives insight into the analysis of free testosterone at physiologically relevant levels in plasma ultra-filtrate, concentrating on the sensitivity, specificity, precision and accuracy advantages offered by GC-MS/MS.
