<p>In accordance with one embodiment of the present disclosure, a lateral flow assay device for determining the ionic strength of urine is described. The device includes a buffering zone having a polyelectrolyte disposed therein, and an indicator zone having a pH indicator non-diffusively immobilized therein, the indicator zone being separate from the buffering zone and positioned adjacent to and in fluid communication with the buffering zone. The device further includes casing material that covers at least a portion of the buffering zone and a portion of the indicator zone so as to prevent exposure of such covered portions to the outside environment.</p> |
