Abstract

The present invention recognizes that it can be desirable to have a sample receiving chamber integral to or engageable with a test platform, such as a test platform that includes a test strip. The sample receiving chamber is preferably separate or separable from the test platform, but that need not be the case. Preferably, a fluid flow actuating device or structure, such as a valve separates the sample receiving chamber from the test platform. A first aspect of the present invention is a test device that includes a sample receiving chamber and a test platform that preferably includes a test element. A second aspect of the present invention is a method of detecting an analyte in a sample, including: providing a sample, contacting the sample with a test device and detecting the analyte in the sample.
