Table 4. Advantages and disadvantages of CS and LBC techniques.
Conventional Smear (CS) | LBC (Filtration) | LBC (Precipitation) | |
Advantages | Better gauge of cellularity | No ROSE needed | No ROSE needed |
Preserved extracellular material | Single slide | Single slide | |
Preserved cytologic architecture | Flatter cell distribution | Improved satisfactory rate | |
Stain options | |||
Disadvantages | Requires ROSE | Increased unsatisfactory rate | More cell crowding/overlap |
More slides to evaluate | Loss of cellularity gauge, extracellular material, cytologic architecture, and stain options | Loss of cellularity gauge, extracellular material, cytologic architecture, and stain options |
CS, conventional smear; LBC, liquid-based cytology; ROSE, rapid on-site evaluation.
