Urine osmolal gap (UOG)

The Urine Osmolar Gap calculator is a valuable tool used to assess the difference between the measured and calculated osmolality of urine. This gap can provide important insights into the presence of unmeasured solutes in the urine, which can be crucial for diagnosing various metabolic and renal disorders. Clinicians often use this calculator to evaluate conditions such as renal tubular acidosis, intoxications, and other electrolyte imbalances.

Understanding the Urine Osmolar Gap:

• Normal osmolar gap: Typically less than 10 mOsm/kg
• Increased osmolar gap: May indicate the presence of unmeasured solutes such as alcohols, sugars, or other substances

While the urine osmolar gap is a useful diagnostic tool, it should be interpreted in the context of a comprehensive clinical evaluation. Factors such as hydration status, medication use, and underlying health conditions can influence the results and should be considered when assessing the osmolar gap.
