a syndrome caused by HIV that renders immune cells ineffective; transmitted sexually or through contaminated blood
a condition of reduced numbers of RBC or hemoglobin resulting in a diminished ability of RBCs to transport oxygen to the tissues
aplastic anemia
a normocytic-normochromic type of anemia characterized by the failure of bone marrow to produce RBC
iron deficiency anemia
a microcytic-hypochromic type of anemia characterized by a lack of iron that affects the production of hemoglobin
pernicious anemia
a macrocytic-normochromic type of anemia characterized by inadequate supply of vitamin B12 causing RBC to become large + vary in shape
autoimmune disease
any disorder characterized by abnormal function of the immune system that causes the body to produce antibodies against itself
erythroblastosis fetalis
a disorder that results from the incompatibility of a fetus with Rh+ blood and a mother with Rh- blood, causing RBC destruction in the fetus
Rh factor
presence or lack of antigens on the surface of RBCs which causes a reaction between Rh+ blood and Rh- blood
Rh positive
presence of antigens
Rh negative
absence of antigens
hereditary disorder with an excessive buildup of iron deposits in the body
a group of hereditary bleeding disorders caused by a defect in clotting factors necessary for the coagulation of blood
chronic or acute malignant disease of the blood-forming organs, characterized by abnormal WBCs in the blood and bone marrow
disorder within the blood marrow characterized by a proliferation of abnormal stem cells; usually develops into a specific type of leukemia
any neoplastic disorder of lymph tissue, usually malignant, as in Hodgkin disease
process by which cancer cells are spread by the blood or lymph circulation to a distant organ
condition caused by the Epstein-Barr virus and characterized by an increase in monocytes and lymphocytes along with swelling and fatigue
increased number of erythrocytes and hemoglobin in the blood

test to measure the activity of prothrombin in the blood
protein substance in the blood that is essential to the clotting process
complete blood count
laboratory blood test preformed as a screen of general health or for diagnostic purposes
white blood count
a count of the number of white blood cells in a given volume of blood obtained via manual or automated laboratory methods
red blood count
a count of the number of red blood cells in a given volume of blood obtained via manual or automated laboratory methods
a test to determine the level of hemoglobin (expressed in grams)
a measurement of the percentage of packed red blood cells in a given volume of blood
blood indices
calculations of RBC, HGB, and HCT results to determine the average size, HGB concentration and content of RBCS to classify an anemia
