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.
Also in Gram staining, crystal violet stains only Gram-positive bacteria, and safranin counterstain is applied which stains all cells, even allowing the identification of Gram-negative bacteria as well. An alternative method uses dilute carbofluozide.. Staining. Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes.
