Serum Osmolality Calculator
Sodium Na mEqL Glucose mgdL BUN mgdL Explanation and Clinical Context Serum osmolality reflects the concentration of dissolved particles in plasma and provides an essential window into the body water balance. The major contributors to serum osmolality are sodium glucose and blood urea nitrogen which form the basis of the widely used calculated osmolality formula. Normal serum osmolality ranges from two hundred sevent
