Abstract
System and method embodiments for analyzing a test fluid to detect prior or present infestations of bed bugs are described. In an embodiment, the method may include receiving the test fluid on a test strip within the detection device. The test strip may include a reaction portion and a reagent portion containing an antibody or antigen-binding fragment that is conjugated to a colored particle. The test fluid may include bed bug antigen that reacts with the conjugated antibody. The detection device may include a first and a second optical sensor for monitoring a reaction and a background color intensity, respectively. Upon a predetermined time delay elapsing, the detection device determines whether bed bug antigen is present in the test fluid using the monitored color intensities and minimum and maximum color intensity thresholds associated with bed bugs. Then, the detection device outputs a result using a visual display.
