MANAGEMENT OF ENDOCRINE DISEASE Hyperandrogenic states in women: pitfalls in laboratory diagnosis

Abstract: Measuring total testosterone level is the first-line approach in assessing androgen excess in women.The main pitfalls in measuring testosterone relate to its low concentration and to the structural similarity between circulating androgens and testosterone, requiring accurate techniques with high specificity and sensitivity. These goals can be achieved by immunoassay using a specific antitestosterone monoclonal antibody, ideally after an extraction step. Liquid chromatography coupled to tandem mass spectrometry… Show more

“…Common clinical indications for these measurements include suspected polycystic ovary syndrome (PCOS) in women, infertility investigations in both sexes and erectile dysfunction in men. 16,17 Where multiple measurements were available in one individual, the first measurement was utilized. Patients with the outcome of interest (T2DM) preceding the index date were excluded from the study.…”

“…В настоящее время предъявляются высокие требования к методам определения концентрации Т. Применение ИФА признано недостаточно точным, особенно в случаях неболь-шого/умеренного повышения уровня гормона, которые и сос-тавляют большинство наблюдений [28][29][30][31]. Наиболее чув-ствительными и специфичными методами определения содер-жания общего Т считаются газовая или жидкостная хромато-графия с масс-спектрометрией (GC-MS или LC-MS) и радиоим-муный анализ с экстракцией органическими растворителями и последующей хромотографией [29][30][31].…”

Желательно, чтобы лаборатории имели собственные диапазоны референсных значений для указанных гормонов, полученные в ходе локаль-ных популяционных исследований [28,30].…”
