- agglunination
- clumping together of cells as a result of interaction with specific antibodies called antigutinins.
- aniscytosis
- abormal condition of the blood characterized by red blood cells of variable and abnormal size.
- antibodies
- substance produced by the body in response to bacteria, viruses, or other foreign substances. Each class of antibody is named for its action.
- antigens
- substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody.
- ascites
- abnormal intraperitoneal (within the peritoneal cavity) accumulation of a fluid containing large amounts of protein and electrolytes
- coagulation
- process of transferring a liquid into a solid, especially of the blood.
- corpuscle
- any cell of the body, red or white blood cell.
- cytogenesis
- The origin and development of cells.
- dyscrasia
- abnormal condition of the blood or bone marrow such as leukemia, aplastic anemia, or prenatal Rh incompatability.
- edema
- abnormal accumulation of fluid in institial spaces of tissues.
- embolism
- The sudden blocking of an artery by a clot or foreign material which has been brought to its site of lodgment by the blood current.
- embolus
- A clot formed by platelets or leucocytes that blocks a blood vessel.
- erythremia
- abnormal increase in the # of red blood cells.
- agglutinins
- used in blood typing and in identifying or estimating the strength of immunoglobulins or immune serums.
- erythroblast
- immature red blood cell.
- erythrocyte
- mature red blood cell.
- erythrocytopenia
- Deficiency in the number of red blood cells
- erythrocytosis
- An abnormal elevation in the number of red blood cells.
- erythropiesis
- process of red blood cell production
- hematologist
- medical specialist in the field of hematology
- hematology
- scientific study of blood and blood-forming tissues.
- hemolysis
- breakdown of red blood cells and the release of hemoglobin that occurs normally at the end of the life span of a red blood cell.
- hemolytic
- is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid
- hemopoiesis
- formation of blood cellular components.
- hemorrhage
- loss of red blood cells and the release of hemoglobbin that occurs normally at the end of the life span of a red blood cell.
- hemostasis
- termination of blood by mechanical or chemical means or by the complex coagulation process of the body, consisting of vasoconstriction, platelets aggregation, and thrombin and fibrin synthesis.
- hyperlipemia/hyperlipidemia
- excessive level of blood fats, usually caused by a lipoprotein lipase deficiency or a defect in the conversion of low-density lipoproteins to high-density lipoproteins.
- hypersplenism
- A condition or group of conditions where the haemolytic activity (red blood cell destruction) of the spleen is increased
- isotonic
- occurs when an equal solute concentration exists inside and outside the cell
- leukocyte
- white blood cell, one of the formed elements of the circulating blood system
- leukocytopenia
- abnormal decrease in # of white blood cells to fewer than 5,000 cells per cubic millimeter.
- lymphocyte
- White cell of the blood that are derived from stem cells of the lymphoid series.
- morphology
- A study of the configuration or the structure of animals and plants.
- myeloid
- of or pertaining to bone marrow or the spinal cord.
- neutrophil
- polymorphonuclear (multilobed nucleus), granular leukocytes that stains easily with neutral dyes.
- pancytopenia
- makred reduction in the # of the red blood cells, white blood cells, and platelets.
- plasma
- water, straw-colored fluid portion of the lymph and the blood in which the leukocytes, erythrocytes, and platelets are suspended.
- platelet/thrombocyte
- clotting cell
- poikilocytosis
- Irregularity of red cell shape.
- purpura
- A small haemorrhage (up to about 1 cm in diameter) in the skin, mucous membrane or serosal surface, which may be caused by various factors, including blood disorders, vascular abnormalities and trauma.
- septicemia
- systematic infection in which pathogens are present in the circulating bloodstream, having spread from an infection in any part of the body.
- seroconversion
- change in sercologic tests from negative to positive as antibodies develop in reaction to an infection or vaccine.
- serology
- branch of labratory medicine that studies blood serum for evidence of infection by evaluating antigen-antibody reactions.
- serum
- clear, thin, and stickly fluid portion of the blood that remains after coagulation.contains no blood cells, platelets or fibrinogens.
- splenomegaly
- abnormal enlargement of the spleen.
- thrombocytopenia
- abnormal hematologic condition in which the # of platelets is reduced.
- thrombosis
- The formation, development or presence of a thrombus.
- thrombus
- a clot.
