Other important hematological parameters are platelet count, clotting time, hematocrit and hemoglobin. Hematocrit and hemoglobin concentrations remain in general unchanged. Targeted cells include&colon; red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. In cases of hemorrhagic shock, hematocrit and hemoglobin can be severely decreased. However, the hematocrit and hemoglobin is decreased. Screening is done with either a hemoglobin or hematocrit lab test. This results from an increased hematocrit and mean cellular hemoglobin content (MCHC). Two other factors significantly affect glucose measurement&colon; hematocrit and delay after blood drawing. Light dye damaged the glycocalyx minimally, but that small change increased capillary hematocrit. It is also linked to a decrease in hematocrit and disturbances in blood clotting. Hyperanemia is a severe form of anemia, in which the hematocrit is below 10%. Alterations in hematocrit and respiratory rate induced by methylene blue. Relationships between hematocrit, viscosity, and shear rate are important factors to put into consideration. Another way of measuring hematocrit levels is by optical methods such as spectrophotometry. Lowered hematocrit levels also pose health impacts.
