Electrolyte Sweat Patch Analysis
Electrolyte sweat patch analysis measures mineral concentration in collected sweat—personalizing sodium and electrolyte drinks beyond one-size sports formulas.
Electrolyte sweat patch analysis collects sweat from skin patches during exercise to estimate sodium, potassium, and sometimes chloride concentration per liter of sweat. Field kits and sports labs use it to personalize drink mixes beyond generic sports-drink labels.
Results vary by body site and session intensity—forearm patches may not match whole-body losses.
Common questions
-
Are sweat patches as accurate as lab whole-body tests?
Patches are useful for field screening but site and technique matter. Lab washdown tests remain the reference when precision drives race nutrition plans.
