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.
A counterstain is a stain with colour contrasting to the principal stain, making the stained structure easily visible using a microscope. Examples include the malachite green counterstain to the fuchsine stain in the Gimenez staining technique and the eosin counterstain to haematoxylin in the H&E stain. In Gram staining, crystal violet stains only Gram-positive bacteria, and safranin counterstain is applied which stains all cells, allowing the identification of Gram-negative bacteria as well. An alternative method uses dilute carbofluozide.
