Yes, it is called anemia.
Hemoglobin is the fluid that transports blood cells. If you get a transfusion of red blood cells, they would be in the hemoglobin even if it is low.
The lack of hemoglobin in the red blood cells is attributed to anemia or iron deficiency. There is no actual condition in itself of lack of hemoglobin in the red blood cells. Hemoglobin times three equals hematocrit, which is the volume of packed red blood cells. A low count of either indicates anemia. This could be the result of an iron deficiency or a protein deficiency, or it could mean internal bleeding. The etiology of the low hemoglobin needs to be determined.
Anemia is a deficiency in the amount of hemoglobin in the blood.
An abnormally low quantity of hemoglobin in the blood is called anemia. Anemia also refers to a low red blood cell count.
blood transfusion and low iron
If you have a low blood pressure, low hematocrit and hemoglobin, you need to have a blood transfusion.
Anemia is the condition of low red blood cell count or low hemoglobin. Anemia results in decreased oxygen-carrying capacity of the blood.
Low BPG levels indicate a low hemoglobin level in the red blood cells.
Iron
hemoglobin is just a pigment in your blood that makes it red...carries oxygen throughout the body...
Microcytic hypochromic anemia is a condition where the red blood cell count and hemoglobin levels are low (hence anemia), with small red blood cells (microcytic), and red blood cells that stain less intensely than normal (hypochromic). The most common cause is iron deficiency. Low levels of iron in the body.
