Low Red Blood Cell Count (Anemia)
Red blood cells carry oxygen throughout the body. Oxygen enters the lungs with each breath and binds (attaches) to hemoglobin in the red blood cells. Hemoglobin carries the oxygen to all the organs and tissues in the body. Two laboratory tests are done to measure the number and function of red blood cells:
A Hemoglobin test shows how much oxygen the red blood cells are able to carry. A normal hemoglobin level is between 12 and 16.
A Hematocrit shows the percentage of red blood cells in the blood. A normal hematocrit is between 36 and 50.
Signs of a low red blood cell count
When the hemoglobin count is low, the body is not able to get as much oxygen to go throughout the body.
A person with low hemoglobin may have the following symptoms:- Tiredness
- Shortness of breath
- Headache
- Fast heart rate
- Pale skin and/or pale gums
- Dizziness
Blood Transfusions
If your child needs a blood transfusion, the blood given will match your child’s blood type. The blood will be given over several hours into a vein, through a central venous catheter or an IV in the arm. Your child will be checked during the transfusion for signs of a reaction.
One of the most common concerns about blood transfusions is the risk of getting HIV/AIDS and hepatitis. The risk of getting AIDS or hepatitis from a blood transfusion is very small. All donors are tested for infectious markers in the blood, such as the HIV virus, hepatitis and others. Blood that tests positive for any disease is thrown away. Although research studies have shown directed donations do not increase blood safety, if it makes you feel more comfortable for your child to receive blood from a family member or friend, such “directed donations” may be available. Blood donations are always welcome, and giving blood is a great way for friends and family to feel like they are helping. For more information about direct donation, ask your health care provider.
