The hematocrit is the proportion, by volume, of the blood that consists ofred blood cells. The hematocrit (hct) is expressed as a percentage. For example, a hematocrit of 25% means that there are 25 milliliters of red blood cells in 100 milliliters of blood. How is the hematocrit meas...
In SI units the hematocrit is expressed as the decimal fraction of the division with the unit L/L. DISCUSSION: Dorland's Medical Dictionary defines "hematocrit" as the "volume percentage of erythrocytes in whole blood". It is well established that if whole (anticoagulated) blood is allowed ...
Thehematocritis the percentage of the volume of blood occupied by RBCs (Figure 5-31). Reference ranges vary with age, gender, and elevation above sea level. The hematocrit is increased in vitamin B12andfolic acid deficienciesand is decreased iniron deficiency. The hematocrit is used to diagnose...

However, the actual number reported as “hematocrit” is none of these things: it is the percentage of the blood volume occupied by red blood cells after blood is centrifuged in a heparinized microcapillary tube under controlled forces and for a prescribed period of time. Thus, the hematocrit ...
