TermDefinition
anemia group of blood disorders inbolving either a reduction i number of circulating erythrocyes or amount of hemoglobin in red blood cells; results in decreased oxygen delivery to tissues
anticoagulant any substance that prevents clot formation
aplastic anemia severe form of anemia caused by loss of functioning red bone marrow; results in decrease in number of all blood cells; may require bone marrow transplant
blood culture and sensitivity blood specimen incubated to check for bacterial growth; if bacteria are present they are identified and best antibiotic treatment is determined
autotransfusion collecting and storing one's own blood to use to replace blood lost during surgery.
blood transfusion transfer of blood fro one person to another
bone marrow aspiration removal of small sample of bone marrow by needle and examined for diseases such as leukemia or aplastic anemia
bone marrow transplant patient receives red bone marrow donation after own bone marrow is deystroyed by radiation or chemotherapy
complete blood count comprehensive blood test that includes red blood cell count (RBC), WBC, Hemoglovin (Hgb) hematocrit(Hct), white blood cell differential and platelet count
Embolus commonly called floating clot; usually piece of thrombus breaks away and floats through bloodstream until it lodges in a smaller blood vessel and blocks blood flow.
erythrocyte sedimentation rate (ESR, sed rate) blood test that measures rate at which red blood cells settle out of blood to form sediment in bottom of test tube; indicates presence of inflammatory disease
hematocrit blood test that measures vlolume of red blood cells within total volume of blood
hematoma blood collection under skin by escaping into tissue from damaged blood vessel; commonly caused bruise
hemoglobin blood test that measures amount of hemoglobin present in a given volume of blood
hemophilia inherited lack of vital clotting factor; results in almost complete inability to stop bleeding
iron-deficiency anemia anemia resulting when there is not enough iron to build hemoglobin for redblood cells
leukemia cancer of leukocyte-forming red bone marrow; patient has large numberof abnormal and immature leukocytes circulating in blood
pernicious anemia anemia resulting when digestive system absorbs insufficent amt of vitiman b12 which is necessary for erythrocyte production
phlebtomy removal of blood specimen from vein for laboratory tets; also called venipuncture
platelet count blood test that determines numbe rof platelets in a given volume of blood
polychthermia vera condition characterized by too many erythrocytes, blood becomes to thick to flow easily through blood vessels
prothrombin time blood test that measures how long it takes for clot to form after prothrombin a blood clotting protein, is activated
red blood cell count blood test that determines number of erythrocyes in volume of blood; decrease may indicate anemia; increase may indicate polycythemia vera
septicemia presence of bacteria or their toxins in bloodstream; commonly called blood poisoning
sequential multiple analyzer computer machine that performs multiple blood chemistry tests automatically
serum blood that had had formed elements and clotting factores removed
sickle cell anemia inherited blood cell disorder in which erythrocytes take on abnormal curve or "sickle" shape; cells are fragile and easily damaged resulting almost exclusively in persons of African descent
thalassemia inherited blood disorder in which blody is unable to correct make hemoglobin resulting in anemia
thrombolytic therapy administering medication to disolve blood clot and restore nomal circulation
white blood cell count blood test that determine snumber of leukocytes in volume of blood; increase may indicate infection or leukemia; decrease may be caused by some diseases, radiation therapy, or chemotherapy
white blood cell differential blood test that determines number of each type of luekocyte
embolo plug
phleb vein
septic infection
cytosis abnormal cell condition- too many
