What type of medication is used to differentiate between normal and abnormal cells during tissue examination?

Antiseptics
Stains
Astringents
Immunosuppressants

The correct answer is: Stains

The correct choice is stains. Stains are specialized chemicals used in histology and pathology to enhance the contrast of different structures within tissue samples. By applying specific stains, a surgical technologist or a pathologist can identify normal cells versus abnormal cells based on their unique characteristics, such as shape, size, and underlying cellular components. This differentiation is crucial during tissue examination to diagnose conditions such as cancer or infections, as it allows for a clearer visual distinction of cellular morphology. Antiseptics are typically used to reduce the risk of infection in surgical settings and are not specifically utilized for cellular differentiation during tissue examination. Astringents generally serve to constrict tissues or reduce bleeding by making the tissue temporarily tight, but they do not assist in identifying cell types. Immunosuppressants are medications mainly used to inhibit or prevent the immune response, which is not relevant in the context of tissue examination for differentiating cell types.
