AFP can be assayed in the range of 0-500 IU/ml using 50 µl serum samples. INTRODUCTION Alpha-fetoprotein (AFP) is a glycoprotein with a molecular mass of 65000. It is normally produced in large amounts by the fetal liver. AFP level increases progressively and reaches a peak at the 30th week in the maternal serum, thereafter, it decreases gradually. An elevated maternal serum AFP is associated with neural tube defect (spina bifida) and placental abnormalities, whereas the decreased AFP levels in both maternal serum and amniotic fluid are related to fetal chromosomal abnormalities. Patients affected by liver carcinoma, testicular or ovarian teratocarcinoma commonly present high AFP levels. Although less frequently, an increased AFP concentration may also be observed in hepatitis, gastric, breast and bronchial tumors. This kit can be used in the risk assessment of Down’s Syndrome (Trisomy 21) in combination with other biochemical and ultrasound parameters as specified above, taking also into account other data like maternal age and weight and using a validated software for Down’s Syndrome risk assessment: Triple test: maternal serum AFP, hCG and unconjugated Estriol determination in the second trimester of pregnancy. Quadruple test: maternal serum AFP, hCG, unconjugated Estriol and Inhibin-A determination in the second trimester of pregnancy. Integrated test: maternal serum PAPP-A determination and nuchal translucency (NT) thickness measurement by an ultrasound scan in the first trimester of pregnancy and maternal serum AFP, hCG, unconjugated Estriol and Inhibin-A determination in the second trimester. 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內(nèi)**地位，公司提供的產(chǎn)品涵蓋了二十多個(gè)國家近五十萬種產(chǎn)品，而且產(chǎn)品的數(shù)量與信息在不斷的增長和更新，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。
