What is a potential consequence of a smear artifact on diagnostic interpretation?

• A. Distortion that improves diagnostic confidence
• B. Distortion of cell morphology that could mislead diagnosis
• C. No effect on interpretation
• D. Enhances clarity of cell borders

Answer: (B)

Smear artifacts distort cell morphology, which can mislead diagnosis. When a slide is prepared, factors like pressure, drying, stain unevenness, or overlapping cells can alter how cells look: nuclei may appear misshapen or indistinct, cytoplasm can be incompletely preserved, and background artifacts can obscure features. These changes can mimic disease features or hide true ones, leading to incorrect interpretation of the sample. That’s why artifacts are a major concern in diagnostic cytology and good technique is essential to minimize them. Artifacts typically do not improve diagnostic confidence or clarity; rather, they hinder accurate assessment.
