ABSTRACT:
A lateral flow immunoassay contact chemical test device and method integrates sample collection, prescreen testing, and confirmation sample collecting and storing with a single device and a minimum of steps. While particularly advantageously used with an oral fluid sample absorbed directly from a person's mouth, (in which constant monitoring of a collection process is made possible), the test device may be used with any of a variety of sample fluids. Prescreen testing and confirmation testing are performed on a single sample. Prescreen testing is performed by a lateral flow assay. The sample collection pad is subsequently separated from the wicking path to prevent continued migration from, and backflow into the sample collection pad, so that the confirmation sample is preserved in the sample collection pad. A multitude of antigens can be detected with a single device.
