Outcome Measures

Primary Outcomes (1)

  • Identification of optical signatures of cervical tissue

    The primary outcome of this study is the identification of the optical signatures of cervical tissue.

    Day of procedure (less than 10 minutes)

Study Arms (1)

Colposcope

EXPERIMENTAL

Patients referred for GYN procedures. Specifically, patients will be referred for Pap smear, colposcope or LEEP. The intervention for this arm is the use of the bench-top, miniature optical spectrometer or trans-vaginal colposcope

Device: Optical Spectroscopy Bench-Top SystemDevice: Portable Optical SpectrometerDevice: Transvaginal colposcope

Interventions

Also known as: TVDC, Transvaginal digital colposcope, Pocket colposcope, callascope
Colposcope

This device is a bench-top optical spectrometer

You may qualify if:

  • undergoing colposcopy for the diagnosis of cervical cancer
  • LEEP for the treatment of cervical cancer in early stages.
  • Follow-up Pap smear in surveillance

You may not qualify if:

  • Women under the age of 18 (minors) will be excluded from this study.
  • patients will be excluded if she has had a recent episode of bleeding or preterm labor.
  • Subjects who are not competent to give consent will excluded
