Strong Ion Difference Calculator

Strong Ion Difference Calculator calculator can be used to calculate the Strong Ion Difference (SID) which is used in the medical field to assess the acid-base balance in the body.

Input Parameters

Sodium (Na+) (mEq/L)

Potassium (K+) (mEq/L)

Calcium (Ca2+) (mEq/L)

Chloride (Cl-) (mEq/L)

Bicarbonate (HCO3-) (mEq/L)

Calculation Results

Calculation Formula

SID = (Na+ + K+) - (Cl- + HCO3-)

Where:
Na+ = Sodium
K+ = Potassium
Ca2+ = Calcium
Cl- = Chloride
HCO3- = Bicarbonate

How to Use the Calculator

Enter the concentration of Sodium (Na+), Potassium (K+), Calcium (Ca2+), Chloride (Cl-), and Bicarbonate (HCO3-) in the respective input fields.
Click the "Calculate" button to compute the Strong Ion Difference (SID).
The result will be displayed in the SID field.

Understanding the Strong Ion Difference (SID)

The Strong Ion Difference (SID) is a measure used to assess the acid-base balance in the body. It is calculated by subtracting the sum of the anions (Cl- and HCO3-) from the sum of the cations (Na+ and K+). The formula is:

SID = (Na+ + K+) - (Cl- + HCO3-)

A positive SID indicates an alkalotic state, while a negative SID indicates an acidic state.
