For a patient with severe anemia, how should the smear angle be adjusted?

Spread angle controls smear thickness. In a patient with severe anemia, the hematocrit is low, so red cells are sparse. If you use the standard angle, the smear can be too thin and cells may be few in the field, making it hard to assess morphology. Increasing the angle from the usual setting produces a thicker smear, increasing cell density in the viewing area and improving visualization of red cell size variation, shapes, and inclusions. This supports more reliable assessment of anisocytosis and other abnormalities. Just avoid making the smear overly thick, which can cause overlapping cells and distort morphology.
