acute lymphocytic leukemia
|
immature lymphocytes predominate. This form is seen often in children and adolescents; onset is sudden
|
|
acute myelogenous leukemia
|
immature granulocytes predominate. Platelets and erthrocytes are diminished because of infiltration and replacement of th bone marrow by large numbers of myeloblasts
|
|
anemia
|
deficiency of erthrocytes or hemoglobin
|
|
antiglobulin test
|
test for the presence of antibodies that coat and damage erythrocytes (Rh-negative in infants)
|
|
apheresis
|
separation of blood into component parts and removal of a select portion from the blood
|
|
aplastic anemia
|
failure of blood cell production in the bone marrow
|
|
autologous transfusion
|
collection and later reinfusion of a patients own blood or blood components
|
|
bleeding time
|
time required for blood to clot from a tiny puncture wound (8 minutes or less)
|
|
blood transfusion
|
whole blood or cells are taken from a donor and infused into a patient
|
|
bone marrow biopsy
|
microscopic examination of a core of bone marrow removed with a needle
|
|
chronic lymphocyte leukemia
|
Abnormal numbers of relatively mature lymphocytes predominate in the marrow, lymph nodes, and spleen. Occurs in the elderly and follows a slowly progressive course. Doesn't require immediate treatment.
|
|
chronic myelogenous leukemia
|
both mature and immature granuloyctes are present in large numbers in the marrow and bloodstream. slow progressive illness with which patients may live many years without encountering life threatening problems. (adults 55 and older)
|
|
coagulation time
|
time required for venous blood to clot in a test tube (usually less then 15 minutes)
|
|
complete blood count
|
determination of numbers of blood cells, hemoglobin concentration, hematocit, and red cell values-MCH, MCV, MCHC

hematopoietic stem cell transplant
|
peripheral stem cells from a compatible donor are administered to a recipient
|
|
hemochromatosis
|
excess iron deposits throughout the body
|
|
hemoglobin test
|
total amount of hemoglobin in a sample of peripheral blood
|
|
hemolytic anemia
|
reduction in red cells due to excessive destruction
|
|
hemophilia
|
excessive bleeding caused by hereditary lack of blood clotting factors necessary for blood clotting

malignant neoplasm of bone marrow
|
|
palliative
|
drugs that relieve symptoms and stop disease progression, which improves the outlook for this disease
|
|
pernicious anemia
|
lack of mature erythrocytes caused by inability to absorb vitamin B12 into the body
|
|
