What happens if the angle of the spreader is too high?

When you spread a drop of blood, the angle at which the spreader is held determines how much the blood is pulled across the slide. If the angle is too high, the blood is deposited more vertically and has less opportunity to fan out evenly. This concentrates cells into a smaller area, making the smear thicker with more overlapping cells and less of the thin, monolayer region that’s ideal for counting and morphology. In practice, a moderate angle around 30–45 degrees helps create a thin, even layer with a feathered edge. A too-steep angle disrupts this, producing a thicker, less useful smear rather than a uniform one.
