The RBC count is almost always part of the CBC (complete blood count) test. The test can help diagnose different kinds of anemia (low number of RBCs) and other conditions affecting red blood cells. Normal RBC range in healthy male is 4.7 to 6.1 million cells per microliter (cells/mcL) whereas in female is 4.2 to 5.4 million cells/mcL.
Higher-than-normal numbers of RBCs may be due to cigarette smoking, problem with heart’s structure and function that is present at birth (congenital heart disease), failure of the right side of the heart (cor pulmonale), dehydration (such as from severe diarrhea), kidney tumor (renal cell carcinoma), low blood oxygen level (hypoxia), scarring or thickening of the lungs (pulmonary fibrosis), bone marrow disease that causes abnormal increase in RBCs.
RBC count will increase for several weeks when we move to a higher altitude. Drugs that can increase the RBC count include Gentamicin and Methyldopa.
Lower-than-normal numbers of RBCs may be due to bleeding, anemia, bone marrow failure (for example, from radiation, toxins, or tumor), deficiency of a hormone called erythropoietin (caused by kidney disease), RBC destruction (hemolysis) due to transfusion, blood vessel injury or other causes like leukemia, malnutrition, bone marrow cancer, nutrition deficiencies of iron, copper, folic acid, vitamin B6, or vitamin B12 and pregnancy.
Drugs that can decrease the RBC count include Chemotherapy drugs, Chloramphenicol, Hydantoins and Quinidine.
