| Anemia | a disorder characterized by levels of RBC's hemoglobin, and hematocrit that are below normal range. |
| Aplasia | The failure of the normal process of cell generation and development, has two etiological classification; congenital and acquired. |
| Disseminated intravascular coagulation | A grave coagulopathy resulting from the overstimulation of clotting factors and anti-clotting processes in response to disease or injury including septicemia, obstetric complications, malignancies, tissue trauma, transfusion reaction, burns, shock, and snake bites. |
| Erythrocytosis | an abnormal increase in circulation erythrocytes. |
| Erythropoiesis | the process of RBC production |
| Hemarthrosis | bleeding into a joint space, a hallmark of severe disease, usually occurring in the knees, ankles and elbow. |
| Hemophilia A | A heredity coagulation disorder caused by an antihemophilic factor VII, which is needed to convert prothrombin to thrombin through thromboplastin component. |
| Heterozygous | having 2 different genes |
| Homozygous | having 2 identical alleles at corresponding loci on homologous chromosomes. |
| Idiopathic | cause unknown |
| Leukemia | malignant disorder of the hematopoietic system in which an excess of leukocytes accumulates in the bone marrow and lymph nodes. |
| Leukopenia | An abnormal decrease in the number of white blood cells to fewer than 5000 cells/mm3 due to depression of the bone marrow. |
| Lymphangitis | inflammation of one or more lymphatic vessels or channels; usually results from streptococcal or staphylococcal infection in an extremity. |
| Lymphedema | primary or secondary disorder characterized by the accumulation of lymph in soft tissue and edema. |
| Multiple Myeloma | a malignant neoplastic immunodeficiency disease of the bone marrow; the tumor is composed of plasma cells. |
| Myeloproliferative | excess bone marrow production |
| Pancytopenia | deficient condition of all three major blood elements; red, white cells and platelets; results from bone marrow being reduced or absent. |
| Pernicious | capable of causing great injury, destruction or death |
| Recombinant | a molecule, a cell, or an organism that results from the recombination of genes, regardless of whether naturally or artificially induced. |
| Reed- Sternberg cells | atypical histiocytes consisting of large, abnormal,multinucleated cells in the lymph nodes found in Hodgkin's lymphoma. |
| Thrombocytopenia | depression of platelet production to < 150,000. |
