Osmolality

Osmolality measures the concentration of dissolved particles, such as salts, sugars, and other small molecules, in a fluid like blood or urine. It indicates how concentrated or diluted a solution is. For example, high osmolality means there are many particles in the fluid, which can affect how your body balances fluids and electrolytes. This measurement helps doctors assess hydration status, kidney function, and balance of fluids and electrolytes, guiding appropriate treatment when there are imbalances or health concerns.
