The Osmolality Urine Test provides a measure of the dissolved particles such as sodium, potassium, chloride, glucose and urea in a urine sample. Osmolality is measured to evaluate the body's water and electrolyte balance. The waste products urea and creatinine are the primary contributors to urine osmolality. Urine Osmolality is typically done to investigate the cause of increased or decreased urine output. These can be caused by conditions such as increased fluid intake, diabetes, dehydration, and kidney damage.
The Urine Osmolality test is often ordered when a person is experiencing unusually high or low urine output. It can be done to aid in the diagnosis of diabetes. It is common to order a Blood Osmolality test at the same time as a urine test for a more thorough analysis.
Turnaround time for the Osmolality Urine test is typically 2-3 business days.
