Question

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

1) hematocrit
2) reticulocyte count
3) red blood cell count
4) ESR

Answer 1

The hematocrit measures the percentage of erythrocytes in a blood sample. It is crucial for diagnosing and managing medical conditions.

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. When a blood sample is centrifuged, the erythrocytes, or red blood cells, separate and settle at the bottom due to their density. This layer, known as the packed cell volume (PCV), typically makes up about 36-50 percent of the blood volume, depending on gender and other factors. The hematocrit value is a crucial measure of the proportion of erythrocytes in blood, and is essential for diagnosing and managing various medical conditions.
