摘要: 目的 探讨己糖激酶(HK)法和葡萄糖氧化酶(GOD)法测定糖尿病患者口服葡萄糖耐量试验(OGTT)检验结果的差异及原因。方法 将进行OGTT的患者分为3组,A组:将75 g葡萄糖溶于300 mL温开水中,令受检者一次服下;B组:口服150 mL 0.5 g/mL葡萄糖注射液,令受检者一次服下;C组:将75 g葡萄糖溶于300 mL温开水中,放置过夜,令受检者一次服下。3组分别于空腹及服后30、60、120、180 min采血分离血清,用HK和GOD法分别测定各时段血糖;比较2种方法血糖测定结果的差异。结果 B组和C组各时段血糖结果HK法和GOD法之间差异无统计学意义(P>0.05);A组空腹血糖2种方法测定结果差异无统计学意义 (P>0.05),而在30、60、120、180 min时2种方法存在明显差异 (P<0.05)。 结论 GOD法对β-D型葡萄糖高度特异,实验室如采用GOD法测定OGTT时,应注意α型葡萄糖影响造成的OGTT曲线偏低的现象。

Abstract: Objective To study the differences and causes of oral glucose tolerance test (OGTT) by hexokinase(HK) method and glucose oxidase(GOD) method.   Methods The patients were classified into A,B and C groups randomly. Orally taking 75 g glucose dissolved in 300 mL warm water was as A group,taking 150 mL 0.5 g/mL glucose injection was as B group,and taking 75 g glucose dissolved in 300 mL warm water placed overnight was as C group. The blood glucose levels at fasting,30,60,120 and 180 min after taking were determined by the 2 methods,and the differences of the results between the 2 methods were analyzed comparatively.   Results There was no statistical difference of blood glucose levels between HK and GOD methods at each determination point in B and C groups (P>0.05). The blood glucose levels in A group between the 2 methods had no statistical significance (P>0.05). The blood glucose levels in A group at 30,60,120 and 180 min had obvious differences (P<0.05).   Conclusions As GOD method is highly specific to beta-D glucose,the phenomenon of a relatively low OGTT curve may occur from the influence of alpha glucose.
