To calculate the Corrected Sodium:
\[ \text{Corrected Sodium} = MS + (0.024 \times (G - 100)) \]
Where:
Corrected Sodium, also known as adjusted sodium, is a calculated value used in medical practice to accurately determine the level of sodium in the blood when there is an abnormal concentration of glucose. High levels of glucose in the blood can cause a phenomenon known as pseudo hyponatremia, where the sodium levels appear to be lower than they actually are. This is because glucose molecules occupy a significant volume in the blood and displace the sodium ions, leading to a dilutional effect. The corrected sodium calculation takes into account the concentration of glucose in the blood to provide a more accurate measure of the sodium level. This is particularly important in conditions such as diabetes, where blood glucose levels can be significantly elevated.
Let's assume the following values:
Using the formula:
\[ \text{Corrected Sodium} = 135 + (0.024 \times (200 - 100)) = 137.4 \text{ mEq/L} \]
The Corrected Sodium is 137.4 mEq/L.
Let's assume the following values:
Using the formula:
\[ \text{Corrected Sodium} = 140 + (0.024 \times (250 - 100)) = 143.6 \text{ mEq/L} \]
The Corrected Sodium is 143.6 mEq/L.
