High osmolality calculation

WebOsmolality is a test that measures the concentration of all chemical particles found in the fluid part of blood. Osmolality can also be measured with a urine test. 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.

WebThe formula used is the following: Osm= 2 * Na + BUN / 2.8 + glucose / 18 + ethanol / 4.6 This is an example calculation: Na value: 140mEq/L BUN value: 13mg/dL Glucose: 76 mg/dL Ethanol: 250 mg/dL Result: Serum Osmolarity: 343.21mOsm/Kg Osmolality v Osmolarity These are both measurements describing the solute concentration in a solution. WebIn healthy people, when osmolality in the blood becomes high, the body releases antidiuretic hormone (ADH). This hormone causes the kidneys to reabsorb water. This results in more concentrated urine. The reabsorbed water dilutes the blood. This allows blood osmolality to fall back to normal. Low blood osmolality suppresses ADH.
