探讨RIA测定甲状腺激素水平的影响因素(运动、饮食、生物节律、药物)对测定结果的影响。T3、T4、FT3、FT4为RIA法,TSH为IRMA法。结果表明,运动、饮食测定结果与对照无显著性差异;轻度脂血对测定结果无影响,重度脂血有影响趋势;TSH昼夜间变化明显,T3、T4、FT3、FT4无昼夜变化;甲状腺素片对T3、T4、FT3、FT4测定结果影响明显,他巴唑对测定结果无影响。RIA测定甲状腺激素应试者状态至关重要,是保证检验结果准确性的先决条件,要高度重视。
To investigate the impact of RIA on the determination of thyroid hormone levels (exercise, diet, biorhythm, drug). T3, T4, FT3, FT4 for the RIA method, TSH IRMA method. The results showed that there was no significant difference between the results of exercise and diet determination and the control. Mild lipids had no effect on the measurement results, and the trend of severe lipids had a trend of change. The changes of TSH in daytime and in the night were obvious, but there was no diurnal changes in T3, T4, FT3 and FT4. Vegetarian tablets on the T3, T4, FT3, FT4 determination results significantly, methimazole had no effect on the determination results. RIA determination of thyroid hormone status of the examinee is crucial, is to ensure the accuracy of test results prerequisite, we must attach great importance.
