Indigenous Technique as an Effective Liquid-Based Cytology Tool for Multiple Single-Layered Cell Preparations

Area of Science:

• Cytopathology
• Cellular analysis

Background:

• Routine cytology and immunocytochemistry often require high-quality cellular smears.
• Liquid-based cytology techniques aim to improve cell preservation and preparation.

Purpose of the Study:

• To evaluate the Modified Millipore technique (MMT) as a liquid-based method for generating multiple monolayer cellular smears.
• To compare MMT with conventional smear preparation for routine cytology and immunocytochemistry.

Main Methods:

• Processed 32 effusion fluid samples and 30 fine-needle aspiration cytology (FNAC) samples.
• Prepared conventional smears and MMT monolayer preparations from residual samples.
• Evaluated cytomorphological features including cellularity, background, nuclear morphology, and cytoplasmic preservation.

Main Results:

• Compared conventional smears with MMT monolayer preparations.
• Statistical analysis (Mann-Whitney U test) indicated no significant difference in quality between MMT and conventional smears (P > 0.01).
• MMT yielded monolayer preparations of comparable quality to liquid-based cytology for both fluid and FNAC samples.

Conclusions:

• The Modified Millipore technique (MMT) is an inexpensive and efficient method for preparing multiple monolayer cell slides.
• MMT is a viable technique for routine cytology and immunocytochemistry laboratories.
• This method facilitates the generation of multiple slides from a single sample for diverse diagnostic applications.
