摘要:

目的 探讨正常新生儿糖化血红蛋白( HbA1c) 的参考区间。方法 使用亲和层析法检测1 003例正常新生儿脐血标本HbA1c医学参考区间按P2.5P97.5计算。结果 新生儿脐血HbA1c呈正偏态分布,中位数为3.80%;95%医学参考值为3.46%~4.25%;新生儿性别、分娩方式对HbA1c结果无明显影响(P>0.05);新生儿脐血HbA1c与新生儿血糖水平呈正相关(r=0.118,P=0.028),与新生儿体重无明显相关性(r=0.064,P=0.168)。结论 新生儿脐血HbA1c可用于监测新生儿血糖水平,确定其参考区间对临床有重要指导意义。

Abstract:

Objective To investigate the reference range of neonatal glycosylated hemoglobin A1c (HbA1c). Methods A total of 1 003 healthy infants were enrolled, and their blood samples from umbilical cord were collected. HbA1c levels were determined by affinity chromatography, and were calculated according to P2.5-P97.5. Results The HbA1c levels showed a positive skewness distribution. The median of HbA1c levels was 3.80%. The 95% reference ranges for HbA1c levels were 3.46%- 4.25%. There was no significant influence of infants' sex and delivery ways on HbA1c levels (P>0.05). There was a positive correlation between HbA1c levels and the blood glucose of infants (r=0.118, P=0.028) and no correlation with the weight of infants (r=0.064, P=0.168). Conclusions HbA1c levels can help for monitoring the blood glucose of infants, and the reference range has an important significance in clinic.
