Sex-specific young adult reference ranges for sex hormone concentrations measured on the Siemens ADVIA Centaur/Geschlechtsspezifische Referenzbereiche für Sexualhormonkonzentrationen junger Erwachsener gemessen auf dem Siemens ADVIA Centaur

Abstract

AbstractThe present study aims to determine reference ranges for sex hormone concentrations measured on the Siemens ADVIA CentaurThe study sample consisted of 1638 individuals (814 men and 824 women) aged 18–60 years with measured serum concentrations of total testosterone (TT), sex hormone-binding globulin (SHBG), and dehydroepiandrosterone sulfate (DHEAS). Values for free testosterone (free T) and free androgen index (FAI) were calculated. Sex- and age-specific (18 to <25, 25 to <35, 35 to <45, and ≥45 years) reference ranges for these sex hormones were determined using quantile regression models for each sex hormone separately.Sex hormone reference ranges were determined across each single year of age separately for men (TT: 5.60–29.58 nmol/L, SHBG: 17.65–73.64 nmol/L, DHEAS: 0.96–4.43 mg/L, free T: 0.10–0.51 nmol/L, and FAI: 15.04–70.37 nmol/L) and women (TT: 0.77–2.85 nmol/L, SHBG: 27.06–262.76 nmol/L, DHEAS: 0.50–3.15 mg/L, free T: 0.005–0.05 nmol/L, and FAI: 0.51–8.30 nmol/L), respectively.
