Abstract
Methods and apparatus for pre-treating swabs prior to collection of specimens to reduce false positive detections by immersing a swab in a liquid chemical pre-treating agent for a treatment period of time. Then the swab is removed and circulated in a rinse agent. The pre-treating agent may be an oxidizing agent, a reducing agent, a bleaching agent (e.g. sodium hypochlorite solution) or a fluorescence suppressing dye (such as Evans blue, Trypan blue, or black dye).
