  1. anemia
    group of blood disorders involving either a reduction in number of circulating erythrocytes or amount of hemoglobin in red blood cells; results in decreased oxygen delivery to tissues.
  2. anticoagulant
    any substance that prevents clot formation
  3. 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.
  4. autotransfusion
    collecting and storing one's own blood to use to replace blood lost during surgery.
  5. blood culture and sensitivity (C&S)
    Blood specimen incubated to check for bacterial growth; if bacteria are present, they are identified and best antibiotic treatment is determined.
  6. blood transfusion
    transfer of blood from one person to another.
  7. bone marrow aspiration
    removal of small sample of bone marrow by needle and examined for diseases such as leukemia or aplastic anemia.
  8. bone marrow transplant (BMT)
    patient receives red bone marrow donation after own bone marrow is destroyed by radiation or chemotherapy.
  9. coagulate
    formation of blood clot
  10. complete blood count (CBC)
    comprehensive blood test that includes red blood cell count (RBC), white blood cell count (WBC), hemoglobin (Hgb), hematocrit (Hct), white blood cell differential, and platelet count.
  11. 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.
  12. 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.
  13. hematocrit (HCT, Hct, crit)
    blood test that measures volume of red blood ells within total volume of blood.
  14. hematoma
    blood collection under skin by escaping into tissue from damaged blood vessel; commonly called bruise.
  15. hemoglobin (Hgb, hb)
    blood test that measures amount of hemoglobin present in given volume of blood.
  16. hemophilia
    inherited lack of a vital clotting factor, results in almost complete inability to stop bleeding.
  17. iron-deficiency anemia
    anemia resulting when there is not enough iron to build hemoglobin for red blood cells.
  18. leukemia
    cancer of leukocyte-forming red bone marrow; patient has large number of abnormal and immature leukocytes circulating in blood.
  19. pernicious anemia (PA)
    anemia resulting when digestive system absorbs insufficient amount of vitamin B12. vitamin B12 is necessary for erythrocyte production.
  20. phlebotomy
    removal of blood specimen from vein for laboratory tests; also called venipuncture.
  21. platelet count
    blood test that determines number of platelets in given volume of blood.
  22. polycythemia vera
    condition characterized by too many erythrocytes; blood becomes too thick to flow easily through blood vessels.
  23. prothrombin time (Pro time, PT)
    blood test that measures how long it takes for clot to form after prothrombin, a blood clotting protein, is activated.
  24. red blood cell count (RBC)
    blood test that determines number of erythrocytes in volume of blood; decrease may indicate anemia; increase may indicate polycythemia vera.
  25. septicemia
    presence of bacteria or their toxins in bloodstream; commonly called blood poisoning.
  26. sequential multiple analyzer computer (SMAC)
    machine that performs multiple blood chemistry tests automatically.
  27. serum
    blood that has had formed elements and clotting factors removed.
  28. sickle cell anemia
    inherited blood disorder in which erythrocytes take on an abnormal curved or "sickle" shape; cells are fragile and easily damaged resulting in anemia; occurs almost exclusively in persons of African descent.
  29. thalassemia
    inherited blood disorder in which body is unable to correctly make hemoglobin, resulting in anemia.
  30. thrombolytic therapy
    administering medication to dissolve blood clot and restore normal circulation
  31. white blood cell count (WBC)
    blood test that determines number of leukocytes in volume of blood; increase may indicate infection or leukemia; decrease may be caused by some diseases, radiation therapy, or chemotherapy.
  32. white blood cell differential (diff)
    blood test determines number of each type of leukocyte.
