中性粒细胞功能障碍,有量和质两个方面.外周血中的粒细胞绝对值低于10~3/毫米~3(正常值为4.5×10~3/毫米~3),为量的缺陷.质的缺陷是中性粒细胞数正常甚至升高,但阻止传染的能力低.质的缺陷可见于慢性肉芽肿、葡萄糖-6磷酸脱氢酶缺乏症、髓过氧化物酶缺乏症、chediak-Higashi综合征以及迟钝白细胞综合征.临床上测定中性粒细胞功能时,常观察其运动 Neutrophil dysfunction, quantity and quality of both the peripheral blood neutrophils in the absolute value of less than 10 ~ 3 / mm ~ 3 (normal 4.5 × 10 ~ 3 / mm ~ 3), the amount of Defects The qualitative defect is that the neutrophil count is normal or even elevated, but its ability to prevent infection is low.Quality defects can be seen in chronic granulomatous, glucose-6-phosphate dehydrogenase deficiency, myeloperoxidase deficiency, chediak-Higashi syndrome and leptin syndrome. Clinically measured neutrophil function, often observe the movement
