Hematocrit-Hematocrit-The hematocrit () (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as part of a blood test. The measurement depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females.... | milkshake721/2.1M-wiki-STEM |
Hematocrit-Hematocrit-Because the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen. Hematocrit levels that are too high or too low can indicate a blood ... | milkshake721/2.1M-wiki-STEM |
Hematocrit-Names-There are other names for the hematocrit, such as packed cell volume (PCV), volume of packed red cells (VPRC), or erythrocyte volume fraction (EVF). The term hematocrit (or haematocrit in British English) comes from the Ancient Greek words haima (αἷμα, "blood") and kritēs (κριτής, "judge"), and hematoc... | milkshake721/2.1M-wiki-STEM |
Hematocrit-Measurement methods-With modern lab equipment, the hematocrit can be calculated by an automated analyzer or directly measured, depending on the analyzer manufacturer. Calculated hematocrit is determined by multiplying the red cell count by the mean cell volume. The hematocrit is slightly more accurate, as th... | milkshake721/2.1M-wiki-STEM |
Hematocrit-Levels-Hematocrit can vary from the determining factors of the number of red blood cells. These factors can be from the age and sex of the subject. Typically, a higher hematocrit level signifies the blood sample's ability to transport oxygen, which has led to reports that an "optimal hematocrit level" may ex... | milkshake721/2.1M-wiki-STEM |
Hematocrit-Shear rate relations-Relationships between hematocrit, viscosity, and shear rate are important factors to put into consideration. Since blood is non-Newtonian, the viscosity of the blood is in relation to the hematocrit, and as a function of shear rate. This is important when it comes to determining shear fo... | milkshake721/2.1M-wiki-STEM |
