| bone marrow MRI | Highly sensitive imaging procedure that detects lesions, and changes in bone tissue and bone marrow, especially in multiple myeloma |
| allergy injections | Injection with increasing strengths of the offending antigen given over a period of months or years to increase tolerance to an antigen responsible for severe allergies |
| reticulocyte | Immature RBC |
| folic-acid deficiency anemia | Inability to produce sufficient red blood cells due to the lack of folic acid, a B vitamin essential for erythropoiesis |
| transfusion | Infusion of blood or blood products from one person to another |
| homologous BM transplant | Infusion of bone marrow or stem cells from a compatible donor after a course of chemotherapy and/or radiation; also called allogenic transplant |
| bone marrow transplant | Infusion of healthy bone marrow stem cells after the diseased bone marrow is destroyed by chemotherapy and/or radiation therapy; used to treat leukemia, aplastic anemia, and certain cancers |
| autologous BM transplant | Infusion of the patient's own bone marrow or stem cells after a course of chemotherapy and/or radiation therapy |
| sickle cell anemia | Inherited anemia that causes RBCs to become crescent-or sickle shaped when oxygen levels are low |
| lymphoscintigraphy | Introduction of a radioactive tracer into the lymph channels to determine lymph flow, identify obstructions, and locate the sentinel node |
| iron-deficiency anemia | Lack of sufficient iron in RBCs |
| monocyte | Leukocyte that is phagocytic; has a large nucleus |
| eosinophil | Leukocyte that protects the body by releasing toxins to destroy harmful invaders |
| basophil | Leukocyte that releases histamines and heparin; slightly phagocytic |
| hematoma | Localized accumulation of blood, usually clotted, in an organ, space, or tissue due to a break in or severing of a blood vessel |
| hypotension | Low blood pressure |
| multiple myeloma | Malignant tumour of plasma cells in bone marrow |
| erythrocyte | Mature red blood cell |
| antifibrinolytics | Neutralize fibrinolytic chemicals in the mucous membranes of the mouth, nose, and urinary tract to prevent the breakdown of blood clots |
