PY - 2017 T2 - Pediatric Endocrinology and Inborn Errors of Metabolism, 2e AB - Many of the most common tests used to diagnose endocrinological disorders are antibody-based immunoassays, although there is a shift toward developing liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays that provide excellent clinical specificity and often superior sensitivity (Table 51-1). Radioimmunoassays (RIAs) pioneered development of immunoassays and further refinement into mass spectrometry methods for quantifying peptide hormones but are not routinely used in clinical laboratories any longer.1,2,3,4 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1140325863 ER -
