Claim 0:
1. An assay device for detecting an analyte in a liquid sample, said assay device comprising an assay device cup and an assay device lid, wherein:
said assay device cup comprises an interior volume configured to hold a liquid sample; and
said assay device lid comprises:
a lid body inlet hole;
an analyte test strip;
a gasket comprising a gasket inlet hole aligned with said lid body inlet hole, wherein said gasket is fit into the assay device lid to retain the analyte test strip in the assay device lid and to separate the analyte test strip from the interior volume of the assay device cup when said assay device lid is engaged with said assay device cup;
a vent hole configurable between an open state and a closed state; and
a label comprising a laser-pierceable material,

wherein the label covers the vent hole to provide the vent hole in the closed state thereby producing an airlock that prevents movement of the liquid sample through the gasket inlet hole and lid body inlet hole to the analyte test strip and piercing the label produces a hole in the label to provide the vent hole in the open state thereby releasing the airlock, thereby providing a metered amount of said liquid sample to said analyte test strip through the gasket inlet hole and lid body inlet hole.
