监测中的意义

甲状腺功能异常是临床上常见的一组疾病。有研究表明，高敏TSH在甲状腺功能诊断方面最为敏感。1999年9月~2000年11月在我科实验室所做的5100人次甲状腺功能检查，以了解三项检测指标在甲状腺功能诊断及监测中的意义。

1资料和方法1.1实验对象我科临床诊断为甲亢①的病人及甲亢服药复查的病人共4518份血标本。1.2实验方法标本收集每次抽肘静脉血3ml，离心后取血清置–20℃保存。检测方法FT3，FT4用放免法，药盒由天津协和试剂公司提供，TSH用免放法，药盒由天津协和试剂公司提供。1.3统计学处理率的比较采用X2检验。第67页，课件共72页，创作于2023年2月2结果4518份标本中，FT3、FT4均增高，TSH降低者有1596份，占总数的35.25%；FT3增高，TSH降低，FT4正常者有564份，占总数的12.46%；FT4、FT4正常，仅有TSH降低者有736份，占总数的16.25%；三项结果均正常者有820份，占总数的18.11%；FT3、FT4正常，而TSH升高者有338份，占总数的7.46%；FT3、FT4降低，TSH升高者有46份，占总数的1.02%；FT4降低，TSH升高，FT3正常者有314分，占总数的6.93%；FT4增高，TSH降低，FT3正常者有46份，占总数的1.02%；其他各种组合有29
