Verified step by step guidance1
Understand that the problem is asking for a term related to the measurement of erythrocytes in a blood sample.
Recognize that erythrocytes are red blood cells, and their measurement is crucial in assessing blood health.
Identify that the term 'hematocrit' refers to the percentage of total blood volume that is occupied by red blood cells.
Differentiate between the options: 'red blood cell count' measures the number of red blood cells, 'reticulocyte count' measures immature red blood cells, and 'ESR' (erythrocyte sedimentation rate) measures the rate at which red blood cells settle in a period of one hour.
Conclude that 'hematocrit' is the correct term for the percentage of total volume used to determine the number of erythrocytes in a blood sample.
