To examine the effect of sampling site on levels of free thyroxine (fT4) and thyrotropin (TSH).
fT4 and TSH were determined by a current immuno-assay in paired samples of capillary and venous blood drawn from 30 euthyroid adults.
Mean levels of fT4 and TSH did not differ significantly between capillary and venous blood; capillary and venous levels correlated well and did not differ significantly from unity.
Sampling site does not influence levels of fT4 and TSH.
研究采样部位对游离甲状腺素(fT4)和促甲状腺激素(TSH)水平的影响。
对 30 例甲状腺功能正常的成年人采集毛细血管血和静脉血,采用当前的免疫分析法测定 fT4 和 TSH。
fT4 和 TSH 的平均水平在毛细血管血和静脉血之间无显著差异;毛细血管血和静脉血水平相关性良好,与 1 无显著差异。
采样部位不影响 fT4 和 TSH 的水平。
