确诊甲状腺功能亢进的实验室检查是（）

A.三酰甘油（甘油三酯）增高

B.三碘甲状腺原氨酸增高

C.β1微球蛋白增高

D.磷酸肌酸激酶减少

E.谷丙转氨酶减少

答案

参考答案：B

解析：临床上把三碘甲状腺原氨酸总量称为TT3，甲亢时血清总T3可升高4倍左右，是诊断甲亢最敏感的指标，B正确。甘油三酯是血脂检查中比较重要的一项指标，其增高只能反映出病人的高脂肪的身体状况，不能作为确诊甲状腺功能亢进的指标，故不选A。临床检测血和尿中的β1微球蛋白，为肾功能测定、糖尿病肾病及肿瘤临床诊断提供较早，较可靠的指标，不能作为确诊甲状腺功能亢进的指标，故不选C。磷酸肌酸激酶增高是诊断急性心肌梗死的主要依据，其减少在临床没有特殊意义，故排除D答案。谷丙转氨酶的正常参考值是0～40U/L，其偏高表明有肝细胞损伤，各类急性慢性病毒性肝炎此值均可升高。谷丙转氨酶偏低在临床没有特殊意义，故排除E。解题关键：此题的解题关键是选择与甲亢有关的实验室指标，其中血清总三碘甲状腺原氨酸是诊断T3型甲亢的特异性指标。【考点】：甲状腺功能亢进的诊断检查

 time.
     "Turning in my exam," replied the student confidently.
     "I'm afraid I have some bad  13  for you," the professor gloated (幸灾乐祸), "Your  14  is an hour late.

     The student smiled slyly (狡诈地)  16  asked the professor, "Do you know who I am?"
     "No," cried out the professor  17 .
