Urine sediments are generally unstained.To improve the contrast,and thus the ability to identify the elements,requires high contrast and lower light.All the other items use a Wright-stained blood film for evaluation.The stain allows for contrast between the various cell components.These procedures are all performed using an oil immersion lens,thus requiring a large amount of light.
