High osmolality calculation
WebCalculate the predicted serum osmolality given the serum sodium, glucose and blood urea nitrogen. 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 more than 10 mOsm/kg is considered an osmolal gap. WebWhy the Test is Performed. This test helps check your body's water balance. Your provider may order this test if you have signs of any of the following: Poisoning from harmful substances such as ethanol, methanol, or ethylene glycol. In healthy people, when osmolality in the blood becomes high, the body releases antidiuretic hormone (ADH).
