Diagnosis and monitoring of therapies for DSD patients require clinical, biochemical and genetic assessments. Biochemical analyses comprise the measurements of peptide and steroid hormones. This position statement, formulated by the COST action DSDnet (BM1303) and the Endo-ERN, provides laboratory guidelines for state-of-the art analysis and interpretation of peptide hormones (e.g. FSH, LH, AMH, inhibin B) in DSD. The authors recommend to measure these peptides in plasma and serum by immunoassays; laboratories should use sex- and age-related reference values and participate in external quality circles. Validation is crucial for harmonization and standardization of tests between different laboratories.

This paper is a ‘must read and follow’ for all health care professionals dealing with laboratory workup of DSD patients. It is written in a comprehensive yet easy-to-digest fashion and summarizes the preanalytical, analytical and postanalytical requirements for high quality laboratory testing of peptide hormones recommended for the workup of DSD. A table summarizes the expected peptide hormone values associated with the most often encountered DSD diagnoses, which is very helpful for interpretation of data during the diagnostic process.

It might be of interest to learn that experts participating in the DSDnet recently published two similar position statements, one on steroid hormone analysis in diagnosis and treatment of DSD (1) and the other on diagnostic genetic approach in DSD (2).
