A perfect blood smear:

  • will have a feathered edge that is nearly square
  • will have a rainbow sheen when reflecting the light
  • will have is exactly one cell thick in the feathered edge when viewed microscopically.

Proper making of the blood smear is essential in obtaining accurate results on the differential count.

Points to be kept in mind while preparing a perfect smear:

a. Delay- smear should be made as soon as the drop of blood is placed on the glass slide without delay. The delay may result in abnormal accumulation of blood cells.

b. Use separate spreader slide for every smear to avoid carryover of patient’s blood on to the next blood smear.

c. Keep the fingers on the spreader slide as far down as possible and apply uniform, moderate pressure to the spreader slide to obtain a good smear.

The too high fingers will cause the excess pressure and result in breakage of the slide. The direction of pressure exerted on the spreader slide must be directed across the slide as in the direction that the film is made.

How to avoid too short smear.

  1. If the smear prepared is too short use a larger droplet of blood.
  2. Slightly decrease the angle of the spreader slide.
  3. Reduce the sliding speed of the spreader slide.
