Abstract:
1. A secretion-monitoring article for identifying a secreted biological fluid comprising: a body that includes an absorbent material for absorbing a biological fluid secreted from a person, and an indicator system that has at least one pH determining member that includes a chemical composition that reacts with fluids that contain urea differently than with fluids that do not contain urea and in a manner such that fluids that contain urea can be distinguished from fluids that do not contain urea while avoiding false positive indications for both fluids, the pH determining member further comprising a hydrophobic chemical composition that reacts with fluids based on the buffer capacity of the fluid, such that fluids having different buffer capacities can be distinguished, wherein the indicator system is associated with the absorbent material such that the biological fluid contacts the indicator system to identify the secreted biological fluid.
