Abstract:
In a dry assay device for determining the concentration of at least one analyte in a fluid test sample which device comprises a strip of absorbant material through which the test fluid can flow which strip has a first region containing specific binding partners for the analyte which are marked with a detectable label and a separate detection region for the labeled binding partners the improvement which comprises in combination a the strip within a hollow casing constructed of a fluid test sample impervious solid material having a top and a bottom which when mated provide a hollow chamber suitable for holding the strip, which chamber is in fluid communication with the exterior of the casing and which casing provides a pathway through which the detection region can be observed from outside the casing and contains a thermally conductive material in thermal communication with the strip of absorbant material.
