A stable labeled internal standard suitable for quantitation of 17α-Hydroxyprogesterone levels in LC-MS/MS testing assays for newborn screening or endocrinology. For LC-MS/MS assays 13C labeled internal standards can offer certain advantages such as eliminating potential issues of isotopic exchange and minimizing separation of later-eluting analytes from a higher substituted deuterium-labeled internal standard.
