Blood Facts Red blood cells, also called erythrocytes, are by far the most abundant cells in the blood. RBCs give blood its characteristic red color. In men, there are an average of 5,200,000 RBCs per cubic millimeter (microliter), and in women there are an average of 4,600,000 RBCs per cubic millimeter.RBCs account for approximately 40 to 45 percent of the blood.BCs give blood its characteristic red color.

- The RBC is your red blood cell count, which usually ranges from 3.6 to 6.1 million red blood cells per cubic millimeter of blood. MCH and MCHC are called red blood cell indices. They measure the average amount of hemoglobin contained within your red blood cells. Don't worry about minor abnormalities in these indices.

Blood Cells and the CBC A typical lab's normal range is 4.2 - 5.4 x 106/µL for females; for adult males it is 4.7 - 6.1 x 106 /µL. C. Hematocrit This is also called the packed cell volume or PCV. It is a measure of the total volume of the erythrocytes relative to the total volume of whole blood in a sample. The result is expressed as a proportion, either unitless (e.g., 0.42) or with volume units (e.g., 0.42 L/L, or 42 cL/L [centiliters/liter]).

Understanding Your Lab Results Many of the blood cell counts discussed below -- including the red blood cells, white blood cells, platelets, differentials, the CD4 cell count, and the CD8 cell count -- are listed on lab reports as the number of cells per cubic millimeter (mm 3 or cu.mm) of blood.n average, a healthy adult has between 4,000 and 11,000 white cells per cubic millimeter or microliter of blood. A high WBC count often means that an infection is present in the body, while a low number can mean that a specific disease or drug has impaired the bone marrow's ability to produce new cells.

BLOOD ANATOMY The formed elements of blood include two types of blood cells: erythrocytes, or red blood cells, and leukocytes, or white blood cells. Erythrocytes are by far the more numerous of the two. A cubic millimeter of blood contains 5.1 million to 5.8 million erythrocytes in males and 4.3 million to 5.2 million erythrocytes in females. The same volume of blood, by contrast, contains only 5,000 to 9,000 leukocytes.

Reference Range MCV is elevated or decreased in accordance with average red cell size; ie, low MCV indicates microcytic (small average RBC size), normal MCV indicates normocytic (normal average RBC size), and high MCV indicates macrocytic (large average RBC size).The reference range for MCV is 80-96 fL/red cell in adult.ndications/Applications. Mean corpuscular volume (MCV) laboratory test, as part of a standard complete blood count (CBC), is used along with other RBC indices (MCH and MCHC) to help classify the cause of anemia based on red cell morphology.

Leukocytes The cellular components of blood include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. Normal human blood contains 4.8 - 5.2 million erythrocytes/ml and 4000 - 10,000 leukocytes/ml. Leukocytes are divided into five classes based on morphological and tinctorial characteristics when stained.

- Sample problem: calculate the MCV and the MCHC for a subject with a red blood cell count of 4x106 per cubic mm, a hematocrit of 40% and a hemoglobin concentration of 12 g/dl.Describe the subject's red cells: are they normocytic? normochromic?hen the MCV is low, they are termed microcytic. Erythrocytes containing the normal amount of hemoglobin (normal MCHC) are called normochromic. When the MCHC is abnormally low they are called hypochromic, and when the MCHC is abnormally high, hyperchromic.

A high red blood cell count is generally defined as more than 5.72 million red blood cells per microliter (mcL) of blood for men and 5.03 million per mcL for women.In children, the threshold for high red blood cell count varies with age and sex.1  Causes. high red blood cell count indicates there are too many red blood cells circulating in your bloodstream.

The normal range for hematocrit varies between sexes and is approximately 45% to 52% for men and 37% to 48% for women.
