Part Description

LP15272-5   Osmolality
Osmolality is the concentration of dissolved substances contained in bodily fluids. An osmolality test can be conducted by measuring the number of particles per kilogram in a sample of fluid (blood, urine, or stool). This test is performed in order to evaluate kidney function and the body's electrolyte/water balance. Typically, osmolality is tested if an individual shows signs of low blood sodium concentration (hyponatremia), alcohol poisoning, an increase/decrease in urine, or chronic diarrhea. When analyzing osmolality, the following particles can be observed in the fluids: sodium, potassium, chlorine, urea, and glucose. Although osmolality tests are able to indicate a water imbalance, the test alone can be inconclusive as to which particular solute is the cause of the health problem.
