|Measures the rate at which anticoagulated RBCs will fall when allowed to settle in a thin columnar tube. The ESR is a nonspecific screening test for inflammatory activity.
|PT: Prothrombin time; an assay that monitors the extrinsic pathway leading to fibrin clot formation. Used to monitor coumadin therapy.
|PTT: An assay that monitors the intrinsic pathway leading to fibrin clot formation. Used to monitor heparin therapy.
|HCT Normal Values (Hematocrit)
|Conditions characterized by a deficiency in quantity or size of RBCs, or hemoglobin content.
|Describes general variation in RBC size.
|Immature form of the segmented neutrophil requiring a separate classification.
|Large, dark purple to black granules
|Caused by a factor IX deficiency.
|A disorder, often triggered by tissue trauma, characterized by massive coagulation that depletes the clotting factors, followed by massive fibrinolysis, which in turn causes severe hemorrhage.
|Contains large, red-orange to dirty-pink granules.
|AKA hemolytic disease of the newborn (HDN). A potentially fatal hemolytic disease, may occur when an Rh neg mother is pregnant with an Rh pos fetus.
|Activation of the coagulation cascade when damaged tissue outside the circulatory system releases factor III into the circulatory system.
|Initiated to break down the fibrin clot that is formed.
|Scientific study of blood and blood-forming tissues.
|Iron-containing portion of the molecule combines with globin (the protein portion) and forms an activated form of hemoglobin that is ready to transport oxygen.
|Characterized by increased hemolysis of red cells. Often due to transfusion reactions, autoimmune disorders, or fetal blood that is incompatible with maternal blood.
|A solution that has a higher concentration of solute outside the cell than inside. This will cause the cell to lose liquid and shrink (crenation).
|A solution that has a lower concentration of solute outside the cell than inside. This will create a rush of liquid into the cell causing it to burst (lysis).
|Activates the coagulation factors within the blood when endothelial lining of the vessel is damaged.
|A neoplastic condition characterized by the proliferation of immature leukocytes in the peripheral blood.
|Are produced primarily by the lymphoid tissue (lymph nodes, thymus, and spleen). Smallest normal WBC
|Results from a vitamin B12 or folic acid deficiency, or both.
|Largest normal WBC.
|0.85 g/dl NaCl solution.
|Enzyme responsible for digesting fibrin or fibrinogen.
|Describes general variation in RBC shape.
|Characterized by an excessive production of RBCs. Increased RBC count, hemoglobin, and hematocrit.
|Eighty-five percent of the population is pos, 15 percent is neg.
|PMNs (polymorphonuclear neutrophils). Most numerous granulocyte
|Shift To The Left
|Increased numbers of bands.
|Shift To The Right
|Increased numbers of segs.
|Caused by a factor VIII deficiency.
