Serum Sodium using Calculated Serum Osmolality Solution

STEP 0: Pre-Calculation Summary
Formula Used
Serum Sodium = ((Calculated Serum Osmolality)-(Serum Glucose/18)-(Blood Urea Nitrogen/2.8))/2
[Na]serum = ((Oserum)-(Gserum/18)-(BUN/2.8))/2
This formula uses 4 Variables
Variables Used
Serum Sodium - (Measured in Mole per Cubic Meter) - Serum Sodium is the concentration of sodium present in the serum of blood.
Calculated Serum Osmolality - (Measured in Mole per Kilogram) - Calculated Serum Osmolality refers to the calculated concentration of dissolved particles of chemicals and minerals such as sodium and other electrolytes in given serum.
Serum Glucose - (Measured in Kilogram per Cubic Meter) - Serum Glucose is the amount of glucose present in the serum of blood.
Blood Urea Nitrogen - (Measured in Kilogram per Cubic Meter) - Blood Urea Nitrogen is a serum byproduct of protein metabolism. It is one of the oldest prognostic biomarkers in heart failure.
STEP 1: Convert Input(s) to Base Unit
Calculated Serum Osmolality: 40 Millimole per Kilogram --> 0.04 Mole per Kilogram (Check conversion ​here)
Serum Glucose: 20.5 Milligram per Deciliter --> 0.205 Kilogram per Cubic Meter (Check conversion ​here)
Blood Urea Nitrogen: 7.5 Milligram per Deciliter --> 0.075 Kilogram per Cubic Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
[Na]serum = ((Oserum)-(Gserum/18)-(BUN/2.8))/2 --> ((0.04)-(0.205/18)-(0.075/2.8))/2
Evaluating ... ...
[Na]serum = 0.000912698412698414
STEP 3: Convert Result to Output's Unit
0.000912698412698414 Mole per Cubic Meter -->0.000912698412698414 Millimole per Liter (Check conversion ​here)
FINAL ANSWER
0.000912698412698414 0.000913 Millimole per Liter <-- Serum Sodium
(Calculation completed in 00.013 seconds)

What is Osmoregulation?

Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis.
