When the blood sample is taken (most often called a “type and screen”), the nurse will place a red blood bank identification (ID) bracelet or armband on the patient. The armband has specific information on it that is used to identify the patient later when a blood transfusion is needed. The blood armband helps ensure your child’s safety.
Blood clot facts and treatment
A blood clot is blood that becomes a solid instead of a liquid. Clotting is normally a good thing. It protects you from bleeding too much. But sometimes you can get a clot that is bigger than normal and not in the right place. These kinds of clots need to be treated.
Blood is made up of cells in a liquid called plasma. Blood cells are made in the bone marrow (the soft center of the bones). In patients with cancer, counting and studying blood cells can tell the staff about a patient's disease and how to treat it.
Blood counts and sickle cell disease
If your child has sickle cell disease, counting and studying blood cells can tell the St. Jude staff about your child’s disease and how to treat it. A complete blood count (CBC) is a test that tells your child’s doctor about all 3 types of blood cells: red blood cells, platelets, and white blood cells.
Calculating the ANC
ANC - The Absolute Neutrophil Count gives your child's medical team an estimate of the body's ability to fight infections, especially bacterial infections.
Receiving a blood transfusion
A blood transfusion may be needed if your child's blood or specific blood parts are at dangerously low levels. A transfusion can replace what is missing.
