Ability of visual tests to predict underlying cervical neoplasia. Colposcopy and speculoscopy.

Abstract

Colposcopy is better suited than speculoscopy to the follow-up of patients with abnormal cervical cytology because it facilitates lesion grading and assists in directing biopsies. Speculoscopy is best utilized as a dichotomous screening test based on the presence or absence of at least one well-demarcated acetowhite lesion and may be more suitable than colposcopy as an adjunct to cervical cancer screening due to its lower overcall rate. The biophysical properties of blue-white chemiluminescent light as it relates to the diagnosis of cervical neoplasia are discussed.
