Evaluation of PathTezt™, a Liquid-Based Cytology System

Area of Science:

• Cytopathology
• Gynecologic Oncology
• Medical Device Evaluation

Background:

• Liquid-based preparation (LBP) cytology is widely adopted for cervical cancer screening due to its convenience and reliability.
• The PathTezt™ is a second-generation LBP system employing a filter-based concentration technique.

Purpose of the Study:

• To assess the cellular fixation, morphology, smear quality, and diagnostic interpretability of cervical cytology specimens processed by the PathTezt liquid-based processor.
• Evaluate the performance of a novel liquid-based Pap smear system.

Main Methods:

• 400 cervical Pap smear samples were processed using the PathTezt 2000 processor.
• Slides were analyzed for sample adequacy, epithelial cell coverage, cellular distribution, obscuring factors, and cell fixation quality.

Main Results:

• 95.25% of samples were satisfactory for evaluation.
• Good cellular distribution (92%) and minimal inflammatory background (88.5%) were observed.
• High-quality fixation and a 99% overall performance rate were achieved.

Conclusions:

• The PathTezt liquid-based processor yields high-quality cervical cytology smears.
• Despite being a newer system, PathTezt demonstrates cost-effectiveness and reliable results for cervical cancer screening.
