1. A body fluid leakage detection aqueous composition, the composition comprising a gelling agent, increasing a viscosity of the composition, wherein the gelling agent is cross-linked starch microspheres or cross-linked dextran microspheres, and buffering species, the composition thereby being buffered, wherein the composition further comprises a pH-indicator, wherein a pH of the composition is at least 0.1 pH units lower, or higher, than a pKa of the pH-indicator, and wherein the volume based mean diameter (D[4,3]), as determined in accordance with ISO 13 320:2009 by using laser diffraction, of the cross-linked starch microspheres, or the cross-linked dextran microspheres, as present in the composition, is 100 to 1000 μm.
