  • Front

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
Anaemia resulting from reduced red cell survival time and haemolysis, either due to an intrinsic defect in the erythrocyte (hereditary spherocytosis or ellipsocytosis, enzyme defects, haemoglobinopathy) or an extrinsic damaging agent.
hemopoiesis
formation of blood cellular components.
hemolytic
is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid
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.
