Abstract
Determination of steroid sex hormones concentrations in children is very important for diasnosis of a wide ranse of pubertal, adrenal and sex development disorders. The majority of hormone measurements are carried out using traditional immunoassays, due to their technical simplicity, cost and availability of commercial reagents. But, due to limited specificity and sensitivity, traditional immunoassays often fail to determine low concentration analytes such as sex hormones in pediatric blood. In the last decade, the LC-MS/MS assay has risen as a new player in the analytic diagnostic field. The assay has proven appropriate for detection of very low hormones concentrations in blood, is quite easy to perform and can detect multiple steroids from a single sample. For the routine determination of an individual or panel of steroids, LC-MS/MS is now the recommended method for most diagnostic laboratories.
