n.(=hematocrit)分血器；血球容积计
Methods:The MPV,blood platelets count (BPC) and haematocrit were detected in 90 ACI patients and 95 health subjects. 方法：对90例急性脑梗塞患者及95例健康体检者进行血液MPV、血小板计数（BPC）和红细胞压积检测。
A haematocrit test measures the total volume that red blood cells take up in the blood. 红细胞压积则测定血液中红血球的总容量。
Almost all types of anaemia will cause a low haematocrit (a low red blood cell volume), as will very severe bleeding. 几乎所有贫血患者的红细胞压积都很低，而且容易出现严重出血。
Results Compared with the observation group，the levels of hemoglobin and haematocrit were significantly increased in control group (P
