Question

Observe the following

What will happen if the step of “Staining the slice of the tissue” in a biopsy procedure is omitted?

• A. The tissue abnormalities will still be visible
• B. The fear of contaminating the sample specimen will be gainfully averted
• C. The important features of the tissue will not be highlighted properly as tissue contrast is impacted
• D. The time required for a complete biopsy procedure will be reduced drastically

Answer 1

The correct option is C The important features of the tissue will not be highlighted properly as tissue contrast is impacted

The main purpose of staining is to highlight cells and parts of cells making observations through a microscope easier. Out of the 20 different types of stains that exist, hematoxylin is the basic one that stains the nuclei giving a bluish colour another stain variant called eosin stains the nuclei pink. Staining provides contrast between the tissues and the background and makes the features distinguishable.
