Use equation 1 from the section to calculate the PCV in each centrifuge tube from the blood sample your group was assigned to test . Record each PCV in the data table below



Answer :

The packed cell volume is checked in cases where there are symptoms of anemia or erythrocytosis.

The PCV which is also known as packed cell volume is equal to the volume of packed red blood cells which is divided by the total volume of the given blood sample.

GIVEN - Red blood cell volumes are -

              5.5 , 5.0 , 5.0 , 5.0 , 4.0

              Total blood mixture volume is -

              10.0, 10.5 , 10.0 , 10.5 , 9.5

SOLUTION - To calculate the packed cell volume -

                      5.5 / 10.0 = 0.55

                      5.0 / 10.5 = 0.47

                      5.0 / 10.0 = 0.5

                      5.0 / 10.5 = 0.47

                       4.0 / 9.5 = 0.42

The main function of packed cell volume is to calculate the red blood cell mass because any increase in the red blood cell mass will be equal to erythrocytosis which means the count of red blood cells is more than the specific sex normal range which is because of plasma volume reduction and also if it decreases then it will lead to anemia because it will have lesser number of red blood cell count and for determining anemia or erythrocytosis the blood test is advised and the reason behind this is cell destruction, blood loss, or failure of bone marrow production and the other name for packed cell volume is hematocrit or volume of packed red cells or erythrocyte volume fraction.
