Answer 1

The percentage of total volume used to determine the number of erythrocytes in a blood sample is referred to as the hematocrit.

Step-by-step explanation:

The percentage of total volume used to determine the number of erythrocytes in a blood sample is referred to as the hematocrit. This is measured by performing a test called a hematocrit, which separates the heavier elements (erythrocytes) from the lightweight plasma in a blood sample. The hematocrit value can vary, but in normal blood, about 45 percent of the sample is erythrocytes.
