  • Front
  • Back
A decrease in the PCV, RBC count or hemoglobin values below normal values
Anemia
Variation in the size of cells
Anisocytosis
Cessation of blood cell formation
Aplastic
A free ruptured nucleus which has swollen so that seperated chromatin can be seen
Basket Cell
1. Increased numbers of basophils in circulation
2. Can also refer to the blue staining of a structure with a Romanowsky stain.
Basophilia
the layer of WBCs, platelets and nucleated RBCs (if present) that collects above the RBCs in sedimented or centrifuged blood
Buffy coat
small irregular blue-grey bodies in the cytoplasm of neutrophils.
Residual RNA. Considered a mild toxic change in most species.
Doehle Body
increased numbers of eosinophils in the blood
Eosinophilia
decreased numbers of eosinophils in the blood
Eosinopenia
the production of RBCs
Erythropoiesis
end product of the clotting mechanism forming a network of fibers
Fibrin
a precision instrument for manually counting cells
Hemacytometer
Red respiratory protein of RBC's that transport O2
Hemoglobin
a condition in which free hemoglobin is present in the plasma
Hemoglobinemia
destruction of RBCs
Hemolysis
a neutrophil with more than 5 lobes present in the nucleus
Hypersegmented
greater than isotonic concentration
Hypertonic
an adjective used to describe a RBC that shows a decrease in the density of hemoglobin present in the cell resulting in increased central pallor = pale
Hypochromic/hypochromatic
increased protein concentration in the blood
Hyperproteinemia
decreased protein concentration in the blood
Hypoproteinemia
less than isotonic concentration
Hypotonic
of unknown cause
Idiopathic
pyknosis and fragmentation of the nucleus
Karyorrhexis
neoplastic disease in which a significant number of blast cells are found
in the bone marrow & blood
Leukemia
resembles leukemia by having a marked leukocytosis or by having a lot of immature cells in the blood - not due to changes in the hematopoietic tissues however
Leukemoid
presence on an increased number of immature (non-segmented)neutrophils in the circulation
Left shift
increased numbers of circulating WBCs
Leukocytosis
decreased numbers of circulating WBCs
Leukopenia
increased numbers of lymphocytes in circulation
Lymphocytosis
decreased numbers of lymphocytes in circulation

a RBC that has a diameter that is larger than normal
Macrocyte
an increased number of large RBCs
Macrocytosis
a large platelet; at least as large as a normal RBC
Macroplatelet
a tissue cell which has granules that contain histamine & heparin
Mast cell
- mean corpuscular hemoglobin concentration - the average hemoglobin saturation, i.e. colour of the RBCs in circulation
MCHC
- mean corpuscular volume
- the calculated average volume of the RBCs in circulation
MCV
a RBC with a diameter/volume which is smaller than normal
Microcyte
an increased number of small RBCs
Microcytic
decreased numbers of monocytes in circulation
Monocytopenia
increased numbers of monocytes in circulation
Monocytosis
anemia which results from the displacement of the narrow by abnormal cells/tissue
Myelophthisic anemia
decreased numbers of neutrophils in circulation
Neutropenia
increased numbers of neutrophils in circulation
Neutrophilia
RBC with normal hemoglobin saturation (MCHC)
Normochromic
see normochromic (another term)
Normochromatic
adjective used to describe a RBC of normal size (volume)
Normocytic
a decrease in all blood cell (RBC, WBC and platelet) lines
Pancytopenia
Clear yellowish fluid portion of the blood in which the cells are suspended.
Plasma
increased number of polychromatic RBCs (have a faint bluish tinge)
Polychromasia
increased RBC mass (PCV) in the body
Polycythemia
a condensation and reduction in the size of a cell
- sign of cell death
Pyknosis
an increase in reticulocytes in circulation
Reticulocytosis
presence of an increased number of hypersegmented neutrophils in circulation
Right shift
the rate at which RBCs settle in their own plasma in a given amount of time
Sedimentation rate
Clear yellowish fluid produced upon seperating whole blood into its solid and liquid components after clotting.
Serum
a platelet that is the size of a RBC and polychromatic
Shift platelet
a RBC which is twice the size of a normal RBC and polychromatic
Shift red blood cell
- a nucleated cell that was ruptured during smearing
- due to mechanical damage or increased fragility of cell
- chromatin has not spread out in distinct strands (see "basket cell")
Smudge cell
use of a stain that has a low toxicity so that "vital and functional processes" can be studied in live cells, eg. New Methylene Blue
Supravital staining
decreased number of platelets (thrombocytes)
Thrombocytopenia
increased numbers of platelets (thrombocytes)
Thrombocytosis
neutrophil showing certain morphologic changes such as vacuolation,toxic granules, increased basophilia or nuclear changes
Toxic neutrophil
