HCT (hematocrit) vs. PCV (packed cell volume) • MSPCA-Angell
What is the difference between HCT (hematocrit) and PCV (packed cell volume) and which is best for clinical use? If you are assessing HCT/PCV over time in a hospitalized patient, the best option is consistency…..use the same method.
Hematocrit/packed cell volume - eClinpath
Hematocrit (HCT) and packed cell volume (PCV) are used to measure red blood cell mass. An increase in red blood cell mass is equivalent to erythrocytosis and a decrease indicates an anemia. Because HCT and PCV are affected by changes in water, the HCT and PCV may be high due to water losses in a dehydrated animal (depending on the extent of ...

血细胞比容测定 - 百度百科
血细胞比容测定又称 红细胞压积 (PCV),是指一定量的抗凝血积压后红细胞占全血的容积比,是一种间接反映红细胞数量、大小及体积的简单方法。 结合红细胞计数和血红蛋白含量,可计算红细胞平均值,有助于贫血的形态学分类。 测定方法有多种,温氏法(Wintrobe)仍是临床常用的方法。 将定量的抗凝血液,注入温氏比积管内,用一定的速度和时间离心,即得沉积红细胞和血浆的比例,从而得知每升红细胞所占体积的比值(L/L)。 (1)干燥的EDTA-Na2 2mg或EDTA …
