T_4抑制试验在青少年甲状腺肿中的选用

T_4 SUPPRESSION TEST IN JUVENILE GOITER

本文报道了50例甲状腺吸^(131)I率高于正常的青少年甲状腺肿患者,给予T_4抑制试验,结合血清T_3T_4和临床表现对甲状腺功能进行判断,认为不能仅以吸^(131)I率、抑制率来确诊甲亢。特别是少年不宜将T_4抑制试验作为常规检查项目,但可在患者临床表现和血清T_3T_4及/or TSH等指标难以确定甲功亢进与否时选用。

This paper reports fifty juvenile goiters given T4 suppression test. Their juvenile thyroid function was evaluated on a clinical basis together with T3- T4 in the serum, It is suggested that Juvenile hyperthyroidism can not be established only by the uptake rate or suppression rate alone. It should be emphasized that teenages cannot take T4 suppression test as a routine test, which is of some value when clinical manifestations, T3 - T4 of serum and/or TSH indexes could not be exactly confirmed.
