CA III FInal Flashcards
malignant neoplastic disorder of lymphoid tissue (not related to Hodgkin disease)
lymphosarcoma
serious, life threatening bloodstream infection that may arise from other infections throughout the body; aka blood infection or blood poisoning
septicemia
laboratory test to detect the presence of antibodies, antigens, or immune substances
serology
blood test that measures the amount of antibodies in the blood; commonly used as an indicator of immune status
titer
test to determine the presence of pathogens in the bloodstream
blood culture
series of tests that includes hemoglobin, hematocrit, RBC, WBC, and platelet counts, differential WBC count, RBC indices, and RBC/WBC morphology
complete blood count (CBC)
test that enumerates the distribution of WBCs in a stained blood smear by counting the different kinds of WBCs and reporting each as a percentage of the total examined
differential count (diff)
measurement of the distance RBCs settle to the bottom of a test tube under standardized condition
erythrocyte sedimentation rate (ESR)
measurement of the amount of hemoglobin found in a whole blood sample
hemoglobin (Hgb) value
measurement of the percentage of RBCs in a whole blood sample
hematocrit (Hct)
non-specific rapid serological test for infectious mononucleosis; aka heterophile antibody test
Monospot
measures the length of time it takes blood to clot. Screens for deficiencies of some clotting factors and monitors the effectiveness of anticoagulant (heparin) therapy
partial thromboplastin time (PTT)
measures the time it takes for the plasma portion of blood to clot. used to evaluate portions of the coagulation system
prothrombin time (PT)
mathematical calculation of size, volume, and concentration of hemoglobin for a RBC
red blood cell indices
used to assess the absorption of radioactive vitamin B12 by the digestive system
Schilling test
radiographic examination of lymph nodes after injection of a contrast medium
lymphadenography
radiographic examination of lymph vessels of tissues after injection of a contrast medium
lymphangiography
drawing in or out by suction
aspiration
uses a syringe w a thin aspirating needle inserted (usually into the pelvic bone) to withdraw a small sample of bone marrow fluid for microscopic examination
bone marrow aspiration
representative tissue sample removed from a body site for microscopic examination, usually to establish a diagnosis
biopsy
removal of a small core sample of tissue from bone marrow for examination under a microscope
bone marrow biopsy
removal of the sentinel node that receives drainage from cancer-containing areas and the one most likely to contain malignant cells
sentinel node biopsy
removal of a lymph vessel
lymphangiectomy
infusion of blood or blood components into the bloodstream
transfusion
transfusion prepared from the recipients own blood
autologous transfusion
