A sweat sodium concentration test, also known as a sweat test, is a diagnostic tool used to assess the level of sodium in an individual's sweat. It is primarily performed to evaluate the functioning of the sweat glands.

The sweat sodium concentration test can be valuable for athletes as it helps assess your sweat sodium loss during exercise, which can be crucial in determining appropriate hydration strategies and preventing conditions like hyponatremia (low blood sodium levels) or dehydration. Understanding your sweat sodium concentration allows us to personalized hydration plans and electrolyte replacement strategies to optimize performance and prevent health complications.
