Article Synopsis
  • DLK1, a protein linked to body weight, shows a decline in levels during infancy and through puberty in girls, with significant reductions noted in healthy infants.
  • The study examined three groups: healthy infant girls, girls going through puberty, and those with central precocious puberty (CPP) undergoing treatment.
  • Results indicate that DLK1 levels are not effective for diagnosing pubertal onset due to variability among individuals, but it does correlate negatively with birth weight and body fat percentage.

Background: Reference intervals covering the whole life span for all the metabolites in the steroid hormone biosynthesis quantified by sensitive and robust analytical methods are sparse or not existing.

Objective: To develop a state-of-the-art LC-MS/MS method for simultaneous quantification of multiple steroid metabolites and to establish detailed sex- and age-specific reference intervals for 16 steroid metabolites.

Materials And Method: An isotope diluted LC-MS/MS method was developed for simultaneous quantitation of 16 steroid hormones.

Objective: To describe the natural history of inhibin B throughout life according to sex, age, and pubertal development.

Methods: Based on serum samples from 2707 healthy controls aged 0 to 80 years, sex- and age-specific reference ranges of inhibin B concentrations were constructed. Concentrations were evaluated according to pubertal development and use of oral contraceptives (OCs).
