Papanicolaou stain, abbreviated Pap stain, is a standard stain used in cytopathology. It is a modified H&E stain.
General
- Can be thought of as the H&E of cytopathology.
- It is a modified H&E stain.
- Specimens are fixed in ethanol.
- Good for seeing nuclear detail.
- Out-of-focus cytoplasm is translucent; allows one to focus overlapped cells in different planes.
Use
- Cytopathology.
Interpretation
- Blue/purple = nucleus.
- Green/pink = cytoplasm.
- Orange = keratin.
