中性杆状核粒细胞是外周血中中性粒细胞的分叶情况为杆状的中性粒细胞。杆状核与分叶核之间的正常比值为1：13，又称为核左移。常见于感染，尤其是化脓菌引起的急性感染，也可见于急性中毒、急性溶血、急性失血等。

结论：白细胞计数总数和淋巴细胞的增加对婴幼儿腹泻病的诊断意义不大，中性粒细胞杆状核细胞绝对数和B/N值确有重要价值。
Conclusion: There no diagnosis value of WBC and lymphocyte to infant diarrhea disease, but neutrophilic band form and B/N value are important for the infant diarrhea diagnosis.
