应用Ｇ－ＣＳＦＥＬＩＳＡ试剂盒，分别测定了４８例怀孕３７～３８周健康孕妇静脉血清，５０例正常足月儿脐静脉血清和４９例脐动脉血清Ｇ－ＣＳＦ阳性率和含量。结果他们的阳性率分别为８．３３％，７４％和８．１６％，并测定了３７例阳性脐静脉血中Ｇ－ＣＳＦ的含量，结果Ｓ／Ｎ均值为５．９０±３．９５，经统计学处理，脐静脉血和孕妇静脉血阳性率有显著性差异（Ｐ＜０．０１），脐静脉血与脐动脉血阳性率也有显著性差异（Ｐ＜０．０１）。
G-CSF ELISA kit was used to measure the positive rate and content of serum G-CSF in 48 healthy pregnant women with 37-38 weeks of pregnancy, 50 normal full-term children with umbilical vein serum and 49 cases of umbilical artery. Results The positive rates were 8.33%, 74% and 8.16% respectively. The content of G-CSF in 37 cases of positive umbilical vein blood was measured. The S / N mean was 5.90 ± 3.95, Statistically, the positive rates of venous blood in umbilical cord blood and pregnant women were significantly different (P <0.01). The positive rates of umbilical cord blood and umbilical cord blood were also significantly different (P <0.01).
