LuViva® Advanced Cervical Scan
The LuViva Advanced Cervical Scan is a medical device that has been designed based on biophotonics science. Biophotonics is used in medicine to study tissue and blood at the macro (large-scale) and micro (very small scale) level to detect, diagnose and treat diseases in ways that are non-invasive to the body.
LuViva is based on 18 technology patents developed by the US based company, Guided Therapeutics, Inc. The technology combines fluorescence with reflectance spectroscopy and analyzes very fine gradations of light from tissue. This form of biophotonics is called Multimodal Hyperspectroscopy (MHS).
The purpose of MHS technology is to eliminate disadvantages of the conventional screening processes (high ratio of false negatives / false positives, unnecessary anxiety and concern, unnecessary colposcopy/biopsy procedures, unnecessary surgeries..etc) and provide a more effective and successful cervical cancer screening process.
LuViva can detect physical and chemical changes in the tissue that occur at the cellular level through reflectance and fluorescence spectroscopy. Thus, high grade cellular dysplasia (HSIL) can be recognised by a far higher sensitivity of 87% compared to conventional methods. Because the MHS technology used by LuViva is very sensitive, it may detect early cellular changes starting at the deep basal layer up to 2 years before conventional methods are able to.
