Which is a problem commonly associated with Picric Acid fixation?

• A. Yellow discoloration of tissue
• B. Improved staining quality
• C. Increased tissue pliability
• D. Reduced fixative hazards

Answer: (A)

Picric acid fixation commonly leaves a yellow color in tissue because the picric acid pigment binds to and stains the tissue, producing a persistent yellow discoloration. This can obscure cellular details and skew the appearance of stains, making interpretation more difficult. To manage it, labs often wash thoroughly or use alternative fixatives to reduce the color before staining. The other statements don’t reflect the typical drawback: fixation with picric acid is not known for improving staining quality, and while it can affect pliability, the hallmark issue linked to this fixative is the yellow discoloration.
