Abnormalities And Irregularities Found In Blood Smears Flashcards
Squashed or distorted lymphocytes caused by excessive pressure on the cells during the process of making the smear
Distorted lymphocytes
A bunch of white cells that may be seen on the edge of the blood smear.
Accumulated white cells
Bare nucleus of ruptured white cells, may be seen in normal blood smear.
Smudge cells
Ruptured cells; both nucleus and the cytoplasm are seen.
Disintegrated cells (Eosinophils)
Caused by:
Incorrect pH of the buffer
Improper mixing of the stain and buffer solution
Too short staining time
Poorly stained eosinophils
Caused by failure to properly flush the excess stain off the slide during the staining process.
Precipitated stain
Granules are large and appear coarse in the cytoplasm.
Neutrophil with toxic granules
Neutrophil broken up to 5 – 10 segments.
Hypersegmented neutrophil
Cells that has holes or vacuoles in the cytoplasm.
Vacuolated cell
Cells that have been squeezed out of the tissue during the finger puncture.
Tissue cells
A net like nucleus from a ruptured white cells.
Basket cells
Also known as “Semilunar Bodies” Believed to be remains of old
erythrocytes.
Crescent bodies
Nucleus become smaller and dense so as chromatin bridges of segments disappear, leaving several small balls of dense chromatin.
Pyknotic cells
Seen in plasma cells as inclusion bodies immediately after therapy with aridine drugs
Snapper-Soheid bodies
Phagocytic cells which are usually a monocyte or a lymphocyte with an engulfed nucleus
Tart cells
