Enter your measured serum sodium and serum glucose levels into the calculator to determine the corrected serum sodium level.

Corrected Serum Sodium Calculation Formula

The following formula is used to calculate the corrected serum sodium level:

Corrected Serum Sodium = Measured Serum Sodium + 1.6 * ((Serum Glucose - 100) / 100)

Variables:

  • Corrected Serum Sodium is the adjusted sodium level based on glucose levels (mEq/L)
  • Measured Serum Sodium is the sodium level measured in the blood (mEq/L)
  • Serum Glucose is the glucose level in the blood (mg/dL)

To calculate the corrected serum sodium, you need to adjust the measured serum sodium based on the serum glucose level. This adjustment is crucial for accurate assessment, especially in patients with hyperglycemia.

What is Corrected Serum Sodium?

Corrected serum sodium refers to the sodium concentration in the blood that has been adjusted for the effects of serum glucose levels. Hyperglycemia can lead to a dilutional effect on serum sodium, making it appear lower than it actually is. Therefore, calculating the corrected serum sodium is essential for proper diagnosis and treatment.

How to Calculate Corrected Serum Sodium?

The following steps outline how to calculate the corrected serum sodium using the given formula:

  1. First, obtain the measured serum sodium and serum glucose levels from the patient’s lab results.
  2. Next, apply the formula: Corrected Serum Sodium = Measured Serum Sodium + 1.6 * ((Serum Glucose – 100) / 100).
  3. Finally, calculate the corrected serum sodium by plugging in the values.
  4. After inserting the variables and calculating the result, verify your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Measured Serum Sodium = 130 mEq/L

Serum Glucose = 250 mg/dL

Using the formula, the corrected serum sodium can be calculated to ensure accurate clinical assessment.

FAQ

1. Why is corrected serum sodium important?

Corrected serum sodium is important because it provides a more accurate representation of sodium levels in patients with altered glucose levels, which can affect treatment decisions.
