What is a hematocrit test? A hematocrit test (Hct) is a simple blood test that measures the percentage of red blood cells in your blood. Red blood cells are important because they carry oxygen throughout your body. Test results showing low or high hematocrit levels may be signs of blood disorders or other medical conditions.

A high hematocrit test result above 48.6% (in men) or 44.9% (in women) is considered above normal and may indicate a blood disorder or other medical condition. What are possible causes of high hematocrit levels?

Your Hematocrit value of 46 % is normal. A good Hematocrit is usually between 36 and 50 %. It is important that the hematocrit stay within normal range so that the red blood cells can deliver oxygen and other nutrients to areas of the body that need them.

红细胞压积 (HCT)又称红细胞比积、红细胞比容，是指一定容积 (L)全血中红细胞所占的体积比例。 它的多少主要与红细胞数量及其大小有关。 温氏法： 男：0.40-0.50L/L ，即40%-50%容积； 女：0.37-0.48L/L，即37%-48%容积； 新生儿：0.48-0.68L/L，即48%-68%容积。 血细胞比容测定的临床意义基本同红细胞计数或血红蛋白测定，常用作贫血诊断和分类的指标。 还可用于临床决定病人是否需要补液及补充电解质的实验检查依据。 (1) 红细胞比容升高： ① 见于剧烈运动或 …

红细胞压积是旧称，现在称红细胞比容（hct）。 红细胞比容是指红细胞在血液中所占的容积的比值。 红细胞比容的测定目的是诊断贫血、真性红细胞增多症和红细胞增多、测定血液稀释和血液浓缩的变化，HCT结合其他血液流变学指标，可用于监测血栓前状态。
