The OralCDx Brush Biopsy (also known as BrushTest® in the dental industry) is a test done in the office to test white/red spots in the patient’s mouth for pre-cancer/cancer cells.
There are two parts to the OralCDx. The brush is designed in a special manner so that it can take a lesion sample painlessly. Unlike typical cytologic smear (PAP smear) which only samples the superficial cells the OralCDx collects cells from all three layers, providing a thorough transepithelial biopsy specimen.
The sample analysis is helped with the use a specialty laboratory where specially-trained pathologists will determine results using sophisticated computers.
