產(chǎn)品名稱(chēng)：17OH-Progesterone free in saliva 產(chǎn) 地：Demeditec 產(chǎn)品貨號(hào)：DESLV3140 產(chǎn)品規(guī)格：96 Tests 產(chǎn)品說(shuō)明： Special remarks: In order to avoid arbitrary results we highly are recommending to always take 5 samples during a 2 hour period and measure the average value of the mixture. We are highly recommending to only use appropriate validated sampling devices like the ones from Demeditec Diagnostics (see Saliva Set in this catalogue). We also are supplying special devices for saliva sampling in newborns and handicapped patients. These are small soft plastic Pasteur pipettes. Please contact us for details. 17alpha-Hydroxyprogesterone (17OHP) is a 21-carbon steroid produced by adrenals, ovaries, testes and placenta. 17OHP is the metabolite of progesterone and 17-hydroxyprognenolone, and is a precursor to cortisol. Serum levels are primarily used to diagnose congenital adrenal hyperplasia (CAH). Deficiency of 21-hydroxylase blocks synthesis of cortisol, resulting in an increase of serum 17OHP levels, which leads to increase in ACTH secretion. Besides the classical CAH, late-onset and milder heterozygous forms of CAH also occur. They may clinically manifest themselves during the peripubertal period in the form of menstrual disturbances and hirsutism. Even in *****hood, hirsutism can signal the possible presence of a heterozygous form of CAH. Measurements of basal and post-ACTH stimulation 17OHP levels are helpful in the differential diagnosis of these conditions. The measurement of 17OHP in serum or plasma samples from babies or young children is difficult because the high concentrations of conjugates present in blood. Therefore such serum and plasma samples should be extracted prior to the assay. The importance of the extraction step increases with decreasing age of the patient. In saliva the interference with the conjugates is not relevant at all, as conjugates are not present in saliva. Therefore salivary measurements of 17OHP even in newborns can be done without extraction step! This is not possible in serum or plasma samples. 上海玉博生物技術(shù)有限公司在為生命科學(xué)領(lǐng)域提供豐富的產(chǎn)品與信息資源方面處于國(guó)內(nèi)**地位，公司提供的產(chǎn)品涵蓋了二十多個(gè)國(guó)家近五十萬(wàn)種產(chǎn)品，而且產(chǎn)品的數(shù)量與信息在不斷的增長(zhǎng)和更新，公司提供的產(chǎn)品能夠使生命科學(xué)工作者加快對(duì)生物化學(xué)，分子生物學(xué)，細(xì)胞生物學(xué)以及蛋白質(zhì)組學(xué)研究的認(rèn)知，以及分子診斷和臨床醫(yī)學(xué)領(lǐng)域的應(yīng)用。
