What is the meaning of pack cell volume?

The packed cell volume (PCV) is a measurement of the proportion of blood that is made up of cells. The value is expressed as a percentage or fraction of cells in blood. The PCV rises when the number of red blood cells increases or when the total blood volume is reduced, as in dehydration.

What happens if PCV is low?

A decreased PCV generally means red blood cell loss from any variety of reasons like cell destruction, blood loss, and failure of bone marrow production. An increased PCV generally means dehydration or an abnormal increase in red blood cell production. TS is a measurement of plasma proteins.

What is normal packed cell volume?

Published data from Europe and North America indicate that for non-iron-deficient adult Caucasian males, the normal mean packed cell volume (PCV) is 0.46 and the 2.5-97.5 percentile interval is 04.0-0.53. Corresponding values for adult Caucasian females are: mean PCV 0.42; 2.5-97.5 percentile interval 0.36-0.48.

What is another term for packed cell volume?

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).

What is the abbreviation for packed cell volume?

Medical Definition of packed cell volume. : hematocrit sense 2 -abbreviation PCV.

What is packed cell volume (PCV) or hematocrit?

Definition: Hct is a macroscopic observation where the percentage volume of the packed RBCs is measured.

Is the packed cell volume (PCV) reliable?

The reliability of the packed cell volume (PCV) has received far less scrutiny than that given to the reliability of hemoglobin and red cell count measurements. The availability of a reference PCV method allowed us to examine 12 different capillary tubes available from scientific supply houses.

How much volume is one unit of packed red blood cells?

Each unit of packed red blood cells PRBC has a volume of 300 mL and contains about 200 mL of red blood cells, which should raise the hemoglobin by about 1 g/dL or the hematocrit by 3-4% in the setting of controlled or slow bleeding. The ultimate outcome measure is mortality.
