Lateral flow immunoassay device and method
First Claim
1. A method of conducting a lateral flow immunoassay comprising:
- providing a housing including means for holding a test sample collector with a test sample contained within said collector;
an elongated holder member securing at least one immunoassay test strip therein;
a first chamber containing a first, pre-treatment reagent; and
a second chamber containing a second reagent;
contacting the test sample with said pre-treatment reagent and allowing said test sample to mix with said first reagent and to form a mixture;
combining said second reagent with said mixture in the second chamber and allowing said mixture to react with said second reagent for a period of time prior to contacting the mixture and second reagent combination with at least one immunoassay test strip; and
allowing the mixture and second reagent combination to contact said at least one immunoassay test strip.

Abstract
A lateral flow immunoassay test device is provided that includes a housing with an elongated slot for holding a test sample collector; an elongated holder member for securing at least one immunoassay test strip therein; a first chamber for storing a first, pre-treatment reagent; and a second chamber for storing a second reagent. Methods of conducting lateral flow immunoassays are also provided. The device and methods of conducting lateral flow immunoassays as provided herein are advantageous in that they allow pre-treatment and pre-incubation of the test sample so that the sample flows onto the test strip more easily and provide for increases in the sensitivity of the assay.
