INTEGRATED CONFIRMATION SAMPLE IN A BODY FLUID TEST DEVICE

摘要

A lateral flow immunoassay contact chemical test device and method integrate s sample collection, prescreen testing, and confirmation sample collecting and storing with a single device and a minimum of steps. The test device (5) may be used with a variety of sample fluids, particularly with oral fluids (16) absorbed directly from a person~s mouth (7). Prescreen testing and confirmation testing are performed on a single sample. Prescreen testing is performed by a lateral flow assay. The sample collection pad (13) is subsequently separated from the wicking path retained within a holder (26) t o prevent continued migration from, and backflow into the sample collection pa d (13), so that the confirmation sample is preserved in the sample collection pad (13). A multitude of antigens can be detected with a single device.
