This method carries out whole immunoassay process including washing and signal reporting simply by dropping a sample to a test strip. During the capillary flow of a sample on the test strip, colored signal bands are produced by the targeted antigen-antibody interactions. In this study, a highly sensitive rapid test was developed by applying a chemiluminescence enzyme reaction. In this method, a chemiluminescent signal band was produced by using horseradish peroxidase (HRP) labeled antibodies and luminol as a chemiluminescence substrate. The intensity of the chemiluminescent signal band was evaluated by using a charge coupled device (CCD) with an image analysis program. The feasibility of the new rapid test with a chemiluminescent signal band was presented by the detection of horseradish peroxidase (HRP) as a model analyte. The applicability of this new rapid test to sandwich-type immunoassays was demonstrated by the detection of myoglobin, and the sensitivity was determined to be improved as much as 100-fold in compared to the conventional rapid test based on colored gold-colloids.
