Calculated Osmolality Low in Blood Calculator
Calculated osmolality low in blood is a critical parameter in clinical chemistry, reflecting the total solute concentration in the plasma. It’s a key indicator of hydration status and can help diagnose conditions like diabetes insipidus and syndrome of inappropriate antidiuretic hormone (SIADH).
How to Use This Calculator
- Enter the concentrations of sodium, glucose, urea, and ethanol in mmol/L.
- Select the desired unit of measurement.
- Click ‘Calculate’.
Formula & Methodology
The calculated osmolality is determined using the following formula:
2 * (Sodium + Glucose + Urea) + Ethanol
If ethanol is not provided, it’s assumed to be 0.
