Whole Body Sweat Electrolyte Test
A whole body sweat electrolyte test measures total mineral loss in a lab—pairing with sweat rate to set precise sodium replacement per hour in heat.
A whole body sweat electrolyte test measures total sodium and mineral loss across the skin using controlled exercise plus collection washdown or absorbent garments in a sports lab. It pairs with sweat rate to calculate grams of sodium lost per hour—not just concentration per liter.
Elite endurance and heat-sensitive athletes use it to build race drink recipes.
