sTSH、FT_3、FT_4甲状腺功能检测中的应用对甲状腺疾病及非甲状腺疾病的

CLINICAL APPLICATION OF sTSH IRMA AND FT_3,FT_4 RIA FOR THYROID FUNCTION DIAGNOSES ON THE THYROID DISEASES AND NONTHYROID ILLNESSES

报告用国产磁分离法药盒的－ＴＳＨ（ＩＲＭＡ）、Ｍ－ＦＴ＿（３）、Ｍ－ＦＴ＿（４）（ＲＩＡ）测定正常人ＴＳＨ６２例，ＦＴ＿３及ＦＴ＿４各１０９例，其均值分别为２．５７±１．１６ｍＩＵ／１、３．７６１±１．５３ｐｍｏｌ／ｌ及１７．１０±４．４１ｐｍｏｌ／１。测定甲亢６１例、甲减５５例，其ＴＳＨ、ＦＴ＿３及ＦＴ＿４均值分别为０．２５±０．０９ｍＩＵ／１、１６．４１±５．０８ｐｍｏｌ／１、４９．５７＋１４．９３ｐｍｏｌ／ｌ及１７．２４±ｌ３．８２ｍＩＵ／１、１．１２＋０．４８ｐｍｏｌ／１、５．０４±２．４５ｐｍｏｌ／１。还分别测定了４４例低Ｔ＿３综合症ＴＴ＿３、ＴＴ－４及ＴＳＨ、ＦＴ＿３、ＦＴ＿４在血循中的水平，并加以讨论。认为ＴＳＨ、ＦＴ＿３、ＦＴ＿４检测对提高甲状腺疾病临床诊断的准确率有重要价值。

sTSH(IRMA)and FT_3,FT_4(RIA)kits which were made in China Institute of Atomic Energy areused tO measure serum TSH,FT_3 ,FT_4 concentrations in171 normal subjects.The mean values are2.57±1.16 mIU/1,3.76±1.53 pmol/l and l 7.1±4.4 l pmol/l respectively.61 hyperthyroid and55 hypothyroid patients are measured ,too. Their mean values of TSH,FT_3 and FT_4 are 0.25±0.09mIU/1,16.41±5.08 pmol/1.49. 57±14.93 pmol/1;17.24 ± l3.82 mIU/1,1.12l± 0.48pmol/1,5.04土2. 45 pmol/l respectively. Furthermore,sTSH,FT_3 and FT_4 are detected and dis-cussed in the 44 nonthyroid ilInesses(NTI).All of TT_3 mean values for NTI are less than those of nor-mal subjects,so this kind of diseases is named low T_3 syndrome.The study deems that sTSH,FT_3 andFT_4 tests are very important and valuable in the diagnosis and differential diagnosis Of thyroid diseasesand NTI.
