hematology ch8 Flashcards
agglutination
clumping of RBCs, joining of antigens and antibodies
rouleaux
(rulo) stacking of RBC, sticky surface on cells from high levels of antibodies
anisocytosis
unequal sizes of RBCs
poikilocytosis
irregular shapes of RBCs
normocytic
normal size RBCs
macrocytic
RBCs of larger size
microcytic
RBCs of smaller size
normochromic
RBCs of normal color
hyperchromic
RBCs more red color, due to hemolysis
hypochromic
RBCs have less red color, lack of hemoglobin
spherocytosis
presence of spherocytes, rounded and lacking central pallor
neutrophil
inflammation infection bacterial products, primary bacterial phagocyte
eosinophils
allergies parasites, anti allergy anti parasite
basophils
exaggerated hypersensitivity, anaphylaxis
lymphocytes
antigens produce antibodies
monocytes
inflammation infection bacterial products, macrophage
red top tube
serum, RTT, blood chemistry, contains nothing
green top tube
plasma, GTT, blood gas analysis, contains heparin
blue top tube
plasma, BTT, coagulation studies, contains sodium citrate
grey top tube
plasma, GTT, blood glucose test, contains oxylate
lavender top tube
plasma, LTT, complete blood count, contains EDTA
aplastic anemia
decrease in RBC or hemoglobin due to no production, bone marrow problems and renal failure
hemolytic anemia
decrease in RBC or hemoglobin due to destruction, body is destroying own cells
hemorrhagic anemia
decrease in RBC or hemoglobin due to loss, bleeding out or losing RBC
agranulocytes
white blood cells lacking granules in their cytoplasm lymphocytes and monocytes
abumin
plasma protein that maintains blood volume
anemia
decrease in RBC or hemoglobin
antibody
proteins produced by white blood cells in response to antigens
antigens
foreign substance that stimulates the production of andibodies
basophils
granulocytic WBC seen in anaphylaxis
bilirubin
metabolite of hemoglobin breakdown, conjugated in the liver
coagulation
blood clotting
eosinophil
ganulocytic WBC seen with allergies and parasites
erythrocyte
RBC
erythropoietin
hormone secreted by the kidneys to stimulate RBC production
fibrin
protein threads that form the basis of a clot
fibrinogen
plasma protein that is converted to fibrin in the clotting process
globulins
plasma proteins such as alpha beta and gamma, antibodies
heme
iron containing portion of hemoglobin
granulocytes
WBC containing granules in their cytoplasm, neurophils, eosinophils and basophils
hemoglobin
oxygen carrying pigment of RBC
leukocyte
WBC
lymphocyte
agranulocyte that produces antibodies
macrophage
monocyte that migrate from the blood to tissue
megakaryocyte
precursor to a platelet formed in the bone marrow
meutrophil
granulocytic WBC thatis the bodys primary bacterial phagocyte
plasma
fluid portion of anticoagulated or circulating blood
prothrombin
plasma potein that is converted to thrombin in the clotting process
reticulocyte
immature RBC
serum
fluid portion of coagulated blood
thrombin
an enzyme that results from the activation of prothrombin
thrombocyte
platelet clotting cell
anticoagulant
agent that prevents coagulation of blood
bleeding time
coagulation test used to measure the time required for a small wound to stop bleeding
bone marrow biopsy
procedure to obtain a bone marrow sample for cytology
complete blood count
blood panel that includes WBC, RBC, and platelet count
disseminated intravascular coagulation
formation of clots throughout microcirculation which leads to hemorrhage due to consumption of clotting factors
dyscrasia
any abnormal or pathological condition of blood
hematocrit
percentage of red blood cells in a volume of blood, packed cell volume PCV
hemophilia
bleeding disorder in which the animal is lacking one or more clotting proteins
hemorrhage
escape of blood through ruptured blood vessels
icterus
yellowish coloration of the plasma caused by increased bilirubin
leukemia
increase in the number of cancerous WBC
lipemia
flat in the blood, white plasma color
phlebotomy
venipuncture the act of drawing blood
transfusion
transfer of blood and blood components from one animal to another
von villebrands disease
congenital bleeding disorder in which the animal is lacking VW clotting factors, pinscher, collie, sheepdog, irish wolfhound

coumarin coumpund found in rodents, once ingested it binds to Vitamin K in the body
white blood cell differential
test to cont the different types of WBC on a slide
