1. A testing article to assess hydration of a test subject, the testing article comprising:
a carrier portion comprising a porous medium through which a fluid of the test subject moves, the carrier portion comprising a first end and a second end opposite the first end, wherein the fluid of the test subject enters the carrier portion at or near the first end;
a first chemical composition disposed in the porous medium, wherein the chemical composition reacts with chloride ions to produce a first color change;
a wick, wherein the wick is in direct contact with the first end of the carrier portion to allow the transfer of the fluid from the wick to the carrier portion;
a fill indicator element in direct contact with the second end of the carrier portion to allow the transfer of the fluid from the carrier portion to the fill indicator element; and
a second chemical composition that reacts with the fluid of the test subject to produce a second color change, wherein the second color change is different than the first color change, wherein the second chemical composition is disposed in the porous medium of the carrier portion; wherein the second chemical composition is configured to migrate along with the fluid of the test subject through the porous medium of the carrier portion and into the fill indicator element.
