These cells may have point-like projections or may include shapes that are flat, elongated, teardrop, or in the shape of a sickle or crescent. When the blood count shows pancytopenia, it is helpful to not only focus attention on erythrocyte morphology, but also to screen the smear for atypical lymphoid cells. The total cell count is registered as well as estimating the average volume and variation in size., A blood sample is taken and sent to a lab for analysis. In: Blood cells: a practical guide [Internet]. A marked increase of dacrocytes is known as dacrocytosis. The normal range of white blood cells per microliter is: 5,000 to 10,000 for men. There, the lab technician looks at it under a microscope. Myelophthisis: displacement of normal hematopoietic tissue in the bone marrow by abnormal cells (malignancies) or fibrosis, leading to bone marrow crowding and pinching of RBCs as they as pushed out of the bone marrow.
