Abstract

The present invention is directed to devices and methods for determining the presence of analyte in a fluid sample. The devices utilize a sample collection well, an expression plate for expressing sample into the sample collection well, a plunger that drives a lance, and a test compartment containing test elements. The devices also preserve an aliquot of fluid sample in a reservoir for later confirmation testing. When the plunger is lowered into the sample collection well, a lance on the device punctures a frangible material that covers a sample outlet. When the sample outlet is thus opened, fluid sample flows from the sample collection cup to the test compartment. In one embodiment the plunger is lowered as a cap is applied to the device. The devices are useful for detecting the presence of analyte in a wide variety of fluid samples, such as saliva, oral fluids, and more. The invention also provides methods of using the devices, and kits containing the devices.
