INTERSTITIAL FLUID CAPTURE DEVICE AND METHOD OF MEASURING ELECTROLYTE LEVELS USING SAME

Abstract

Embodiments of the inventive concept include an interstitial fluid capture device configured to capture an interstitial fluid sample from the mouth of a user, an electrolyte measurement kit including the device, and a method for measuring electrolyte levels using the device. An exemplary device includes a main body portion configured for placement in the mouth of a user, the main body portion including a reservoir containing a hypertonic solution and having an opening that is sealed by a semipermeable membrane that permits a sample of interstitial fluid from the mouth of the user to be drawn through the membrane and into the solution reservoir. Various analyses may be performed on the captured interstitial fluid sample after removal of the device, including but not limited to, the assessment of one or more electrolyte levels through the use of various test strips or other techniques.
