Hematology S&T 1

Blood Liquid tissue containing plasma & formed elements
Erythrocytes Red Blood Cells
Leukocytes White Blood Cells
Thrombocytes Platelets; cells which initiate clotting process
Neutrophils WBC responsible for phagocytosis; increases during short tem/acute infections
Basophils WBC which releases histamine; increases during allergic reaction
Eosinophils WBC which counteracts histamine
Monocytes (Aka Macrophage) WBC responsible for phagocytosis; increased during long-term or chronic infections
Lymphocytes WBC responsible for maintaining the immune system; includes T-cells and B-cells
Antigen any foreign substance that is harmful to the body
Antibody defense mechanism; immune response to an antigen
Plasma Liquid portion of whole blood; contains clotting factors- found ina tube that contains an anticoagulant
Serum liquid portion of clotted blood that doesn't have clotting factors; found in a tube that does not contain an anticoagulant (Ex: SST/Red)
Erythrocytolysis Destruction of red blood cells
Hemostasis to stop bleeding
Megakaryocyte cell in bone marrow which produces thrombocytes
Leukocytosis increase in WBC's; increases during bacterial infections
Leukopenia decrease in WBC's; increases during viral infections or in pts. w/ bone marrow depressions such as cancer patients on chemotherapy
Morphology the study of the shape of cells
Phagocyte a cell capable of ingesting foreign substances and other cells
Phagocytosis "cellular eating"
Macrophage (Aka Monocyte) WBC capable of phagocytosis
Poikilocytosis RBC that vary in cell shape
Anisocytosis RBC that vary in cell size
Hyperchromasia RBC that have an increased red color
Hypochromasia RBC that have a decreased red color
Normochromasia RBC that have a normal red color
Polychromasia RBC that vary in red color
Reticulocyte immature, nucleated RBC
Thrombus blood clot
Thrombolysis destruction of a blood clot
Thrombocytopenia decreased amount of platelets
Hemoglobin iron containng pigment of RBC; helps transport oxygen
Hemopoiesis formation of a blood clot
Anticoagulant medication or chemical that inhibits blood from clotting
Dyscrasia any blood abnormality
Hematoma localized collection of blood under the skin
Serology the study of Serum (Serology blood tests are drawn in an SST/RED top tube)
Transfusion receiving blood to replenish blood lost
Cross-Match blood test to determine whether donated blood will be compatible with recipient's blood (RED TOP TUBE ONLY)
Bleeding Time test to determine the amount of time it takes for a small incision to stop bleeding
Complete Blood Count (CBC) Test to determine the cellular components of blood
Reb Blood Cell Count Test to determine the approximate number of RBC's in a cubic millimeter (CU/MM) of blood
Hematocrit test to determine the percentage of RBC's in a volume of blood
Differential test to determine the percentage of the five types of WBC's- Neutrophils, Lymphocytes, Monocytes, Eosinophils & Basophils)
Erythrocyte Sedimentation Rate (ESR) Test that measures the speed at which RBC's settle in a tube of anticoagulated blood
Prothrombin Time Pt. test to determine the amount of time it takes for a clot to form
Hemostatics medications or chemicals used to stop bleeding
Phenylketonuria Test (PKU) test done on newborns at birth and at 4-6 weeks of age; if positive and untreated- may lead to mental retardation
Hemophilia hereditary disease where there is a lack of factor VIII and the blood doesn't clot properly
Lancet small, sharp instrument used to perform capillary punctures
Capillary Puncture puncture of a capillary to withdraw blood (FINGER, HEEL, BIG TOE, EAR LOBE OR INNER ARM)
Venipuncture Surgical puncture of a vein to withdraw blood
Phlebotomy incision into a vein to withdraw blood
Tourniquet strap used to occlude the veins when performing venipuncture
Glucolysis destruction of glucose
Glucometer instrument used to measure the amount of glucose in blood
Biohazardous Waste waste that is considered to be contaminated and potentially infectious
Hepatitis B viral infection and inflammation of the liver causing jaundice
Antecubital Fossa the inside of the elbow
Albumin the most abundant protein in the blood
Arteriole small artery
Artery vessel which carries blood away from the heart
Basilic Vein large vein of the inner side of the upper arm (PINKY SIDE)
Cephalic Vein Large vein on the outer side of the upper arm (THUMB SIDE)
Accessory Cephalic Vein vein on outer side of arm which empties into the cephalic vein
Median Cubital Vein large vein in the middle of the upper arm (ANTECUBITAL FOSSA) Vein that is most commonly used for venipuncture
Buffy Coat thin layer between plasma and RBC in a volume of anticoagulated blood; contains WBC's and Platelets
Ecchymosis bruising
Petechiae pin-sized red dots on the skin caused by broken capillaries
Hemapheresis process where blood is withdrawn from a patient
