摘　　要：目的比较双位点酶免法（Ｔｗｏ－ｓｉｔｅＥＬＩＳＡ）和时间分辨荧光免疫法（ＤＥＬＦＩＡ）测定新生儿ＴＳＨ的结果。方法采用芬兰进口试剂盒测定２１８例足月正常新生儿足血和脐血的成对ＴＳＨ值。结果ＥＬＩＳＡ法和ＤＥＬＦＩＡ法测定的脐血ＴＳＨ值有明显的相关性，其相关系数ｒ＝０．９１（ｔ＝３２．４１，Ｐ＜０．００１）；两种方法测定的足血ＴＳＨ值也有良好的相关性，其相关系数ｒ＝０．７８（ｔ＝１８．４０，Ｐ＜０．００１）；ＥＬＩＳＡ法测定值在足血和脐血间的相关系数却甚低，ｒ＝０．２１（ｔ＝３．１７，Ｐ＜０．０１）；ＤＥＬＦＩＡ法测定值在两者间的相关系数也很低，ｒ＝０．１５（ｔ＝２．２４，Ｐ＜０．０５）。结论ＥＬＩＳＡ和ＤＥＬＦＩＡ两种方法测定的脐血和脐血之间、足血和足血之间均呈现良好的正相关。Objective To make comparation of cord and heel blood thyrod stimulating hormone levels in neonates.Methods A total pairs of TSH values in both cord and heel blood samples from 218 newborns were detemined by highly sensitive immunoassay (ELISA as well as DELFIA).Results The correlation coefficient of pair results by two methods are as follows:r=0.91(t=32.41,P<0.001);for cord bloods and r=0.78(t=18.40,P<0.001) for heel specimens,respectively.The correlation coefficient of cord and heel sample are as follows: r=0.21(t=3.17,P<0.01) for ELISA and r=0.15(t=2.24,P<0.05) for DELFIA,respectively.Conclusions It was demonstrated that the values detemined by two methods were significantly correlated,but those between cord and heel blood data were not so good.
