Abstract

Objective: To evaluate the historical shift from cytological diagnosis to molecular detection of Chlamydia trachomatis, outlining the precise current role of cervical cytology in clinical practice.
Methods: Historical perspectives, updated international clinical guidelines, and recent technological literature were analyzed.
Results: Papanicolaou smear examination for C. trachomatis demonstrates poor sensitivity (<30%) and high false-positive rates caused by degenerative vacuoles and cellular artifacts. Nucleic Acid Amplification Tests (NAATs) represent the current diagnostic standard. Recent advancements in 2025–2026, including multiplex PCR platforms and point-of-care (POC) testing, have further solidified molecular diagnostics.
Conclusions: Cytology should not be used for direct diagnosis or screening of C. trachomatis. However, it remains a valuable tool for neoplastic screening and an indirect indicator of cervical inflammation, prompting targeted molecular testing.
