Assay Background

5α-androstane-3α, 17β-diol glucuronide is a C19 steroid and is either abbreviated as 3α-Diol G, 5α diol G or simply, α diol G. It is produced mainly as a metabolite of testosterone and dihydrotestosterone (DHT). It is largely produced in target peripheral tissues such as the skin, especially around hair follicles. The stimulation by large amounts of 3α-Diol G leads to excessive hair formation, notably where hair is not normally present in women. In recent years the interest in the measurement of this steroid has increased among clinical investigators studying women suffering from idiopathic hirsutism. Among the steroids known to be precursors for 3α-Diol G are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), dihydrotestosterone (DHT), androstenedione and testosterone. Only 3α-Diol G has been shown to increase with hirsutism and decrease with treatment. This correlation has also been demonstrated in patients with polycystic ovarian syndrome (PCO). 3 α-Diol G determinations have therefore proved to be a useful indicator in a variety of ways including monitoring the progress of treatment of idiopathic hirsutism and women with PCO. Furthermore, diabetic patients (both men and women) under cyclosporine A therapy have shown increased 3 α-Diol G levels, a side effect resulting in the appearance of hair in previously hairless areas.

SPECIMEN COLLECTION AND STORAGE
Approximately 0.2 mL of serum is required per duplicate determination. Collect 4–5 mL of blood into an appropriately labelled tube and allow it to clot. Centrifuge and carefully remove the serum layer. Store at 4°C for up to 24 hours or at -10°C or lower if the analyses are to be done at a later date. Consider all human specimens as possible biohazardous materials and take appropriate precautions when handling.

EagleBio的5α-雄甾烷-3α，17β-二醇葡糖醛酸化物是C19类固醇，缩写为3α-DiolG，5α二醇G或简称为α二醇G。它主要作为睾丸激素和二氢睾丸激素（DHT）的代谢产物生产。它主要在目标外围组织（例如皮肤）中产生，尤其是在毛囊周围。大量的3α-DiolG刺激会导致过多的头发形成，特别是在女性通常不存在头发的地方。近年来，在研究患有特发性多毛症的妇女的临床研究人员中，人们对这种类固醇的测量越来越感兴趣。已知是3α-DiolG前体的类固醇包括脱氢表雄酮（DHEA），硫酸脱氢表雄酮（DHEAS），二氢睾丸酮（DHT），雄烯二酮和睾丸激素。已显示只有3α-DiolG随多毛症增加而随治疗减少。这种相关性在多囊卵巢综合征（PCO）患者中也得到了证明。3α-DiolG的测定因此被证明是多种方式的有用指标，包括监测特发性多毛症和PCO妇女的治疗进展。此外，接受环孢霉素A治疗的糖尿病患者（无论男女）均显示3α-DiolG水平升高，这种副作用导致以前无毛的区域出现了头发。3α-DiolG的测定因此被证明是多种方式的有用指标，包括监测特发性多毛症和PCO妇女的治疗进展。此外，接受环孢霉素A治疗的糖尿病患者（无论男女）均显示3α-DiolG水平升高，这种副作用导致以前无毛的区域出现了头发。3α-DiolG的测定因此被证明是多种方式的有用指标，包括监测特发性多毛症和PCO妇女的治疗进展。此外，接受环孢霉素A治疗的糖尿病患者（无论男女）均显示3α-DiolG水平升高，这种副作用导致以前无毛的区域出现了头发。
