ToggleIf your number of RBCs is lower than normal, you have anemia. For instance, if my rbc is 3.6, it means I have a kind of anemia, which can be caused by a decrease in RBC production or by the destruction or loss of RBCs. There are many possible causes of anemia, including:
– Nutritional Deficiency
– Bone marrow failure
– Hemolysis
– Chronic conditions
– internal or external bleeding
– Menstruation with heavy bleeding
– thyroid disorders (4)
Note that an abnormal result doesn’t always mean you have a problem. Because several factors can affect your RBC count, including:
– Dehydration, less intake of water
– Overhydration, high intake of water
– Stress
– Altitude
– Pregnancy
– Certain medications
– Your position during the test

Human red blood cells (RBC) are highly differentiated cells that have lost all organelles and most intracellular machineries during their maturation process. Their main physiological role is to transport gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria (1,2).
The RBC count is almost always part of a complete blood count (CBC) test, which measures many components in your blood. Test results may vary depending on your age, gender, health history, the lab used, etc. But generally are:
· men 4.0 to 5.9 (×1012/L)
· women 3.8 to 5.2 (×1012/L) (3)
Treating a low red blood cell count depends on what’s causing it and includes:
– iron supplements or iron infusions through veins
– taking vitamin supplements.
– certain medications
– bone marrow transplant
– treating the underlying condition
– blood transfusion (4)
