A hematocrit, answer choice B packed cell volume. Answer choice C, erythrocyte volume fraction or answer choice D red blood cell count. Let's work this problem out together to try to figure out which of the following answer. Choices refers to the percentage of red blood cells in the blood. So first let's recall what we mean by the percentage of red blood cells in the blood. And this percentage is calculated as the volume of those red blood cells divided by the total volume of blood. And since it is a percentage, it is multiplied by 100%. Well, looking at our answer choices, we can see that answer choice D which says red blood cell count, we note that red blood cell count only refers to that volume of red blood cells and not the percentage as a whole. So answer choice D can be eliminated. And answer choice B and C are both terms that are used interchangeably with the term hematocrit to describe that measure of the volume of red blood cells divided by the total volume of blood in the body, which is that percentage of the red blood cells giving us the correct answer, which is answer choice. A hematocrit since hematocrit is a measure of the volume of the red blood cells in relation to that total volume of the blood and is expressed as a percentage.
