red cell count

Red Cell Count

The number of red cells per volume of blood, measured in microliters (µL) or cubic millimeters (mm3). At birth, the red cell count is increased, which is followed shortly by a decrease that ‘bottoms out’ at ± 2 months of age, then slowly rises to adult levels; polycythaemia is defined as an increase in red cells of any cause, which may be neoplastic, as in polycythaemia vera, or nonneoplastic—erythrocytosis or secondary polycythaemia—due to various factors—high altitudes, smoking, cyanotic heart defects, and chronic obstructive pulmonary disease; decreased red cell count—anaemia—can, like polycythaemia, be physiologic—as in marathon runners—or pathologic
Reference range
Males 4.1-5.4 x 1012/L—US: 4.1-5.4 x 106/µL
Females 3.8-5.2 x 1012/L: 3.8-5.2 x 106/µL. RBCs, WBCs, platelets are counted by automated devices

count [kownt]

a numerical computation or indication.

Addis count the determination of the number of erythrocytes, leukocytes, epithelial cells, and casts, and the protein content in an aliquot of a 12-hour urine specimen; used in the diagnosis and management of kidney disease.

blood count (blood cell count) see blood count.

blood count, complete a series of tests of the peripheral blood, including the erythrocyte count, erythrocyte indices, leukocyte counts, and sometimes platelet count.

blood count, differential differential leukocyte count.

erythrocyte count determination of the number of erythrocytes in a unit volume of blood that has been diluted in an isotonic solution, done with an automatic counter such as a flow cytometer. Called also red blood cell or red cell count.

leukocyte count determination of the number of leukocytes in a unit volume of blood, usually after the erythrocytes have been lysed and the blood has been diluted; it may be done either manually with a hemacytometer or electronically. See total leukocyte c. and differential leukocyte c. Called also white blood cell or white cell count.

leukocyte count, differential a leukocyte count that calculates the percentages of different types. See also total leukocyte count.

leukocyte count, total a leukocyte count measuring the total number of all the types in a given volume of blood. See also differential leukocyte count.

platelet count determination of the total number of platelets per cubic millimeter of blood; the direct platelet count simply counts the cells using a microscope, and the indirect platelet count determines the ratio of platelets to erythrocytes on a peripheral blood smear and computes the number of platelets from the erythrocyte count.

red blood cell count (red cell count) erythrocyte count.

reticulocyte count a calculation of the number of reticulocytes in 1 cu mm of peripheral blood, recorded either as an absolute number or as the percentage of the erythrocyte count. It provides a means of assessing the erythropoietic activity of the bone marrow.

white blood cell count (white cell count) leukocyte count.

red cell count

Erythrocyte count Hematology The number of RBCs per volume of blood, measured in microliters–µL or cubic millimeters–mm3; at birth, the RCC is ↑, which is followed shortly by a ↓ that 'bottoms out' at ± 2 months of age, then slowly rises to adult levels; polycythemia is an↑ in RBCs of any cause, which may be either neoplastic, as in polycythemia vera, or nonneoplastic–erythrocytosis or 2º polycythemia, due to various factors–high altitudes, smoking, cyanotic heart defects, and COPD; ↓ RBC count–anemia can, like polycythemia, be physiologic–as in marathon runners or pathologic Ref range ♂: 4.1-5.4 x 1012/L–US: 4.1-5.4 x 106/µL; ♀: 3.8-5.2 x 1012/L: 3.8-5.2 x 106/µL. RBCs, WBCs, platelets are counted by automated devices. See Anemia, Hematocrit, Red cell indices.

Patient discussion about red cell count.

Q. what is a normal red blood cell count for breast cancer after operation

A. i know that the normal count is between 4.2 to 5.9 million cells/cmm. if you have anything else- i think this question should be to the Doctor...cause even if someone here will tell you it's ok that it's a bit low- the Doctor should know that and he has your chart with all your medical information. there for i would give him a phone call to ask if it's o.k. - unless you are in the normal average i told you, then you shouldn't worry about it.
