Biological stain IVD

Biological stains for in vitro diagnostics (IVD) are chemical dyes or solutions designed to highlight specific structures in clinical specimens, such as cells, tissues, or pathogens. Used primarily in microscopy, these stains enhance visibility to aid in diagnosing infections, blood disorders, or other conditions by differentiating cellular components or microorganisms.

These stains are typically regulated as IVD reagents, often requiring compliance with standards for safety, performance, and labeling. They are commonly supplied as single-use solutions or kits, with classification depending on their intended use and risk level. Always verify local regulatory requirements before use.
