Rapid sample collection and analysis device and methods of use
First Claim
1. A test device for detecting an analyte suspected of being present in a fluid sample, comprising:
- a casing, comprising a port for a sample collection well;
a sample collection well, situated in the port and comprising an expression plate, and a plunger having a raised position and a lower position;
a chamber for storage of a confirmation sample;
a test compartment containing at least one test element;
a sample outlet sealed by a frangible material and providing liquid communication between the sample collection well and the test compartment when the sample outlet is open;
a lance for piercing the frangible material; and
a cap for the sample collection well, wherein a portion of the cap interacts with the plunger to move the plunger from the raised position to the lower position when the cap is applied to the sample collection well.

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.

24. A method of detecting the presence of an analyte in a fluid sample comprising,
applying the fluid sample to a device comprising, a casing comprising a port for a sample collection well; -
a sample collection well, situated in the port and comprising an expression plate, and a plunger having a raised position and a lower position;
a chamber for storage of a confirmation sample;
an expression plate;
a test compartment containing at least one test element;
a sample outlet sealed by a frangible material and providing liquid communication between the sample collection well and the test compartment when the sample outlet is open; and
