Hematology Laboratory Reports

Flashcards covering key concepts and definitions related to Hematology and Red Blood Cell Morphology.

Erythrocytes

Red blood cells that are round with a pale center.

Macrocytic

A type of red blood cell that is very large.

Microcytic

A type of red blood cell that is very small.

Anisocytosis

Variation in size of red blood cells.

Poikilocytosis

Presence of abnormally shaped red blood cells.

Polychromatophilia

Appearance of red blood cells when stained with dyes under a microscope.

Nucleated Red blood cells

Larger red blood cells with a dark center.

Target cell

A red blood cell with a bullseye appearance.

Ovalocyte

A red blood cell that is oval in shape instead of circular.

Elliptocyte

A red blood cell that is elliptical as opposed to circular.

Burr cell

A red blood cell with spiny projections instead of round cells.

Sickle cell

An elongated red blood cell instead of round.

Spherocyte

A small, round, densely stained red blood cell without an area of pallor.

Malaria

Contains small, ring-shaped structures within infected red blood cells.

Iron Deficiency Anemia

Characterized by hypochromic and microcytic red blood cells.

Thrombocytosis

A condition with a high number of platelets and clumping observed.

Thrombocytopenia

A condition with a low number of platelets that are fewer and irregularly shaped.

Giant platelets

Platelets that are significantly larger than normal.

Neutrophil

A round cell with a multi-lobed nucleus.

Lymphocyte

A white blood cell with an enlarged nucleus and no granules.

Monocyte

A white blood cell with a horse-shoe shaped nucleus.

Basophil

A white blood cell that is all purple with granules clumped inside.

Eosinophil

A white blood cell with granules inside and two lobes to its nucleus.

Infectious Mononucleosis

Characterized by large, atypical lymphocytes with deep blue cytoplasm.

Acute Lymphocytic leukemia

Features a nucleus that takes up most of the cell space.

Chronic lymphocytic leukemia

Presents as 'smudge cells' that appear flattened and damaged.

Multiple myeloma

Characterized by a large, eccentric nucleus and abundant cytoplasm.

Chronic Myeloid leukemia

Features Philadelphia chromosome and a high number of immature WBC forms.
