Abstract
An assay device for testing for the presence of an analyte in a sample liquid supported on a test surface, the device comprising a test stick having a handle portion to be held by a person performing the test and a mixing portion to contact the sample liquid, the mixing portion bearing a dried, pre-dosed reagent for the test, the dried reagent being reconstituted by contact of the mixing portion of the test stick with the sample liquid, and wherein the mixing portion is configured to provide a mixing surface to mix the reconstituted reagent with the sample liquid on the test surface.
Claims9
An assay device for testing for the presence of an analyte in a sample liquid, the device comprising a test stick having a handle portion to be held by a person performing the test and a mixing portion to contact the sample liquid, the mixing portion bearing a dried, pre-dosed reagent for detecting the analyte, the dried reagent comprising an antibody specific for a Lancefield group-specific streptococcal antigen, and being reconstituted by contact of the mixing portion of the test stick with the sample liquid, and wherein the mixing portion is configured to provide a mixing surface to mix the reconstituted reagent with the sample liquid supported on a test surface not forming part of the test stick.
A method of testing for the presence of an analyte in a sample liquid, comprising using a test stick having a handle portion to be held by a person performing the test and a mixing portion bearing a dried, pre-dosed reagent for the test which reagent comprises an antibody specific for a Lancefield group-specific streptococcal antigen;
- contacting the mixing portion of the test stick with the sample liquid supported on a test surface not forming part of the test stick so as to reconstitute the test reagent;
- moving the mixing portion relative to the test surface so as to cause mixing of the reconstituted reagent with the sample liquid;
- and determining the test result.
