β-羟基丁酸简介除了许多其他临床应用外,Stanbio化学系列的LiquiColor®β-羟基丁酸(B-HB)试剂还用于检测酮,以鉴定患有糖尿病性酮症酸中毒的患者。
β-羟基丁酸检测试剂是监测酮症的有效方法β-羟基丁酸是糖尿病酮症酸中毒期间存在的最主要的酮类,并且随着患者的临床状况呈上升趋势。由于β-羟基丁酸测定法是定量的,因此可用于监测酮症的分解,使其成为优越的酮试验。 我们的β-羟基丁酸检测试剂已在美国1,100多家医院中使用,并且可以在实验室分析仪的开放通道上运行。 此外,β-羟基丁酸可用于临床诊断和监测酒精中毒、糖原贮积病、高脂/低碳水化合物饮食、怀孕、碱中毒、摄入异丙醇和水杨酸中毒的病情或严重程度。 β-羟丁酸检测试剂的规格

为什么要检测糖尿病酮症酸中毒?
当I型糖尿病患者没有足够的胰岛素时,他们可能处于危险之中。胰岛素是一种人体用来分解血液中的糖分(葡萄糖)以提供能量的激素。当身体感觉葡萄糖不充足时,脂肪就会被分解。 为什么β-羟基丁酸检测是诊断酮症酸中毒的重要方法?
当人体由于能量(葡萄糖)供应不足而开始分解其储存的脂肪时,会生成酮β-羟丁酸(B-HB),该酮进一步分解代谢为乙酰乙酸酯,然后再分解为丙酮。 与硝普钠方法相比,B-HB(β-羟基丁酸)对酮症和酮症酸中毒的检测效果更好,原因如下:
1.β-羟基丁酸酯具有出色的稳定性,是临床上相关酮症和酮症酸中毒的重要指标。 参考1.Savage MW, Dhatariya KK, Kilvert A, Rayman G, Rees JA, Courtney CH, et al.
