鲁伦云1145C肽的正常参考值范围是怎样的?
廉毅冒19593485212 ______ 空腹C肽水平为0.3〜1.3mmol/L;C肽释放试验:口服葡萄糖后30分钟至1小时出现高峰,其峰值为空腹C肽的5〜6倍.

鲁伦云1145c - 肽0.66正常吗? -
廉毅冒19593485212 ______ 正常值为:0.8-4.2ng/ml. C肽对糖尿病的鉴别有重要意义,C肽是由胰岛B细胞分泌形成的多肽,C肽值和胰高血糖素类似,饭后一小时出现最大值,是空腹的四到五倍,饭后两小时含量逐渐下降慢慢趋于平稳,C肽与胰岛素有一个共同的前体胰岛素原,胰岛B细胞的分泌功能反映了机体血糖调节能力,C肽则反映了胰岛B细胞的分泌功能. 正常人空腹C肽的参考值范围是0.8-4.2ng/ml,相当于0.3-1.3nmol/l.血液C肽的正常值是0.3~1.3mmol/l,餐后1-2小时含量逐渐上升出现最大值,此时含量是空腹的四到五倍.一段时间后由于胰岛素等激素的作用,C肽含量开始下降最后处于一个稳定的状态.

鲁伦云1145请问关于C肽的测定方法?
廉毅冒19593485212 ______ 目前国际上采用的标准用C肽来评价胰岛B细胞功能的试验为胰升糖素试验,即病人先抽空腹血测C肽,然后快速静脉注射1毫克的胰升糖素,第6分钟时抽血测定C肽,正常...
