An elevated serum osmolality is the most powerful stimulus for antidiuretic hormone (ADH) release. ADH production increases in a hyperosmolar state when osmolality reaches 280 mOsm/L (Ober 1991). Sodium, the predominant osmotically active particle determining serum osmolality, is the most potent ion with regards to ADH stimulation (Robertson 1984).

The normal range of serum osmolality is 285-295 mOsm/kg. The measured osmolality should not exceed the predicted by more than 10 mOsm/kg. A difference of …

Osmolality is measured in the laboratory using an osmometer. The calculated and measured osmolality can be compared to determine if there are other particles present (in addition to sodium, potassium, glucose and urea) that contribute to the measured serum osmolality. Serum osmolality is a measure of the number of osmotically active solute particles (such as sodium) per kilogram of serum. It can help differentiate between hypertonic (or hyperosmolar) hyponatraemia, pseudo-hyponatraemia (or osmotic hyponatraemia), and hypotonic (or true) hyponatraemia. Serum osmolality will be normal in patients with pseudohyponatraemia (i.e., total body sodium and water are unchanged, with no shift of fluid between intracellular and extracellular compartments).

Often you will be asked for a sample of urine for urine osmolality testing too. The serum osmolality is extremely close to the osmolality inside the cells that our body is made of. Osmolality therefore is an ideal measurement to estimate the total concentration of solutes in a near limitless variety of liquid sample matrices, including blood, serum, plasma, urine, milk, cell culture media and almost all forms of aqueous based solutions.
