Methods, materials, apparatus and systems are described for performing capillary flow assay. In one aspect, a system includes a sample collection unit to collect a sample liquid and a sample testing and storing unit to interface with the sample collection unit to test and store the collected sample liquid. The sample testing and storing unit includes a sample inlet shaped to receive the collected sample from the sample collection unit, and a sample well positioned below the sample inlet to retain at least a portion of the sample liquid. The sample testing and storing unit includes a sample housing unit to store a remainder of the sample liquid not retained in the sample well, and an analyte testing unit housing shaped to receive an analyte detecting unit to test a presence of a target analyte in the sample liquid.

Capillary flow solid phase assay

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.
