Frequently Asked Questions
Serum osmolality measures the concentration of dissolved particles in the blood. It helps assess hydration status and electrolyte balance.
The formula is: 2 × Na⁺ + Glucose/18 + BUN/2.8, where Na⁺ is in mEq/L, glucose and BUN in mg/dL.
Normal serum osmolality ranges from 275 to 295 mOsm/kg. Values outside this range may indicate medical conditions.
