近年来,随着医学检验技术日趋自动化,电子血细胞计数议已为众多实验室所装备。我们在使用时,发现一例小儿肺炎患者体外红细胞聚集引起的假性红细胞减少。患儿初××,女,九岁。因发热,伴咳嗽,右胸痛,经抗菌素治疗无明显效果而入院(病案号85148)。入院时查:末稍血白细胞计数7.3×10~9/L,中性分叶0.58,淋巴细胞0.30,嗜酸细胞0.1,单核细胞0.2,血红蛋白13.9克%,胸透见“右肺中野大片密度高,边缘模 In recent years, with the increasingly automated medical testing technology, electronic blood cell count protocol has been equipped for many laboratories. When we were using, we found a case of pediatric pneumonia in vitro erythrocyte aggregation caused by pseudo-erythrocyte reduction. Children early × ×, female, nine years old. Due to fever, with cough, right chest pain, no significant effect by antibiotic treatment and admission (case number 85148). Admission check: the end of the leukocyte count 7.3 × 10 ~ 9 / L, neutral leaf 0.58, lymphocytes 0.30, eosinophils 0.1, monocytes 0.2, hemoglobin 13.9%, chest see "right lung in the wild High density, edge mode
