ZedScan Clinical Trials

Identification and detection of cervical disease

The ability to identify correctly those women who have and those who do not have disease is pivotal to the success of any screening programme. Prevention of cervical cancer depends on colposcopic detection and treatment of high-grade cervical intra-epithelial neoplasia (CIN 2+) in women referred with abnormal cytology.

A number of clinical studies have been completed to assess the performance of an EIS based diagnostic device in the diagnosis of cervical intraepithelial neoplasia (CIN) – Table 1.

*Conclusion from pivotal multicentre trial:

" The use of EIS as an real-time adjunct to colposcopy improves clinical performance. The inclusion of EIS into colposcopic practice could lead to more appropriate patient management with lower intervention rates.
