what stain is used to stain eosinophils
Eosinophils can be detected in the urine by applying stains that attach to their cytoplasmic granules. The three most commonly used stains are the Wright's, Giemsa, and Hansel's stains, and the last is the most effective at staining eosinophils in the urine [6,7]. The presence of more than 1 percent eosinophils of the total white cells in the urine is considered a positive test by any of these three stains.
