本文报道150例甲亢、85例甲减患者血清rT_3的测定结果,分析其诊断价值。两组rT_3的变化均非常明显(P<0.001),甲亢组rT_3升高小于T_3,大于T_4,诊断符合率86.7％,低于T_3和T_4;甲减组rT_3下降的程度及诊断符合率(94.2％)均超过T_3T_4,仅次于TSH,表明血清rT_3反映甲减比甲亢敏感,尤对早期甲减有重要意义。本结果提示,血清rT_3可作为诊断甲减较有价值的指标。
This article reports 150 cases of hyperthyroidism, 85 cases of hypothyroidism serum rT_3 measurement results, analysis of its diagnostic value. The rT_3 in hyperthyroidism group increased less than T_3 and higher than T_4, the diagnostic coincidence rate was 86.7%, lower than that of T_3 and T_4. The degree of decrease of rT_3 in hypothyroidism group and the diagnostic coincidence rate (94.2 %) Were more than T_3T_4, second only to TSH, indicating that serum rT_3 reflects hypothyroidism than hyperthyroidism sensitive, especially for early hypothyroidism is of great significance. The results suggest that serum rT_3 can be used as a diagnostic hypothyroidism more valuable indicators.
