Grocott's Methenamine Silver Stain, technical only
Use
Grocott methenamine silver (GMS) stain is used to detect fungi, including Pneumocystis jirovecii, the causative agent of Pneumocystis pneumonia. This stain imparts a black color to fungal cell walls, facilitating their identification under a microscope. Additionally, GMS can stain other organisms and non-organic substances, such as melanin, mucins, and glycogen, providing valuable diagnostic information.
