摘要
【目的】 探讨采血时间对正常足月新生儿一周内干血滴纸片促甲状腺素测定的影响。 【方法】 选择健康母亲分娩的正常新生儿为研究对象 ,然后按不同的时间进行标本的采集 ,用时间分辨镧系荧光免疫分析法进行干血滴纸片TSH含量的测定。 【结果】 正常新生儿出生后 1～ 2小时TSH迅速上升至 15 .1mIU/L ,随即快速下降至 11.1mIU /L ,以后则逐渐下降 ,到 5 5小时以后TSH基本稳定在一个较低的范围内。 【结论】 新生儿足跟血纸片检测TSH的最佳采集时间应在出生 5
Objective To study the effect of different bloodpicking time on the concentration of TSH in dry blood drop piece from newborns within one week. Methods Normal newborns born of healthy mothers were chosed as objects,from whose heels blood drops were picked.Concentrations of TSH in dry blood drop pieces were measured by DELFIA. Results Concentration of TSH climbing up to 15.1mIU/L in normal newborns within 1～2 hours afrer delivery rapidly,following goes down to 11.1mIU/L.Afterwards,concentration of TSH decreases gradually,and maitains at lower level afrer 55 hour after delivery. Conclusions Anytime after 55 hour after delivery is thought as the best blood picking time in the screening of newborn dysthyroidism.
