Morphology of the blood cells on a PBF smear is best discussed in line with each haemopoietic cell lineage. The distribution, size, shape, color, cellular inclusions of the red blood cell (RBC) and morphology of the other major cell lines should be carefully assessed.

5 paź 2023 · Examination of the peripheral blood smear is an inexpensive but powerful diagnostic tool in both children and adults. In some ways, it is becoming a "lost art," but it often provides rapid, reliable access to information about a variety of hematologic disorders.
17 sie 2023 · A blood film looks at our three cell types (erythrocytes, leukocytes & platelets) under a microscope to identify any abnormalities to give visual clues regarding the functional state of the bone marrow & any systemic diseases.
Pencil cells are a type of abnormally elongated thin-shaped red blood cells (RBCs) morphology seen on a peripheral blood smear. Appearance on Blood Smear Elongated Shape: The defining feature of a pencil cell is its markedly elongated shape, resembling a pencil lead in terms of RBC morphology.
The best place to examine blood cell morphology is the feathered edge of the blood smear where red cells lie in a single layer, side by side, just barely touching one another but not overlapping. The author’s approach is to look at the smallest cellular elements, the platelets, first and work his way up in size to red cells and then white cells.
Examination of the peripheral blood smear should be considered, along with review of the results of peripheral blood counts and red blood cell indices, an essential component of the initial evaluation of all patients with hematologic disorders.
9 mar 2022 · Mean corpuscular (cell) volume (MCV) - guideline normal values: 77-95 fL. This is a good starting point for the evaluation of anaemia and usefully classifies anaemia into macrocytic and microcytic anaemias.
