Immunoassay test device and method of use
First Claim
1. A testing device comprisinga) a receptacle with an open and a closed end,b) a holder, andc) a lateral flow test strip,wherein the holder is comprised of (i) an elongated portion for affixing the test strip to the holder, (ii) a closure that substantially seals the open end of the receptacle when the holder is inserted into the receptacle thus creating a closed test environment, and (iii) a grip member that extends from the open end of the receptacle;
- andwherein the test strip is positioned so lateral flow is initiated when the holder is inserted into the receptacle.

Abstract
Disclosed is a diagnostic testing device that may be used to detect one or more analytes in a sample. The device comprises a receptacle and a holder for a test strip. The test strip may be, for example, a lateral flow test strip. The device and holder permit analysis of a sample, wherein the device is substantially sealed during testing and detection of results. To use, the holder containing a test strip is inserted into the receptacle containing sample to be analyzed. Capillary flow along the test strip is initiated by contact of the sample with the distal end of the test strip. The receptacle is such that results of the assay may be detected visually or using standard instrumentation such as by measuring light absorption or reflectance.
