摘要
目的:探讨血清T_3/T_4、FT_3/FT_4在亚急性甲状腺炎(SAT)和Graves'病(GD)中的差异,为临床鉴别提供新方法。方法:收集SAT患者110例,GD患者143例,另外选择85例作为正常对照组,采用放射免疫法(RIA)测定方法检测三组T_3、T_4值,比较并分析血清T_3/T_4、FT_3/FT_4在GD、SAT和正常组之间的差异。结果:血清T_3/T_4比较示,SAT组低于对照组(P<0.05);GD组明显高于对照组(P<0.01);GD组明显高于SAT组(P<0.01)。血清FT_3/FT_4组间比较示,SAT组与对照组间比较无统计学差异(P>0.05);GD组明显高于对照组(P<0.01);GD组明显高于SAT组(P<0.01)。血清T_3/T_4<14.7提示SAT,T_3/T_4>18.4提示Graves'病;FT_3/FT_4>0.42提示Graves'病,FT_3/FT_4<0.38提示SAT或者甲状腺功能正常。结论:血清T_3/T_4、FT_3/FT_4在鉴别诊断SAT和GD中具有临床意义,且血清T_3/T_4对GD和SAT的鉴别诊断价值优于FT_3/FT_4。
