Enter the change in anion gap and the change in bicarbonate gap into the Delta Ratio Calculator. The calculator will evaluate and display the Delta Ratio.

## Delta Ratio Formula

The following formula is used to calculate the Delta Ratio.

DLR = AG / BG
• Where DLR is the Delta Ratio
• AG is the change in anion gap
• BG is the change in bicarbonate gap

To calculate a delta ratio, divide the change in anion gap by the change in bicarbonate gap.

## How to Calculate Delta Ratio?

The following example problems outline how to calculate Delta Ratio.

Example Problem #1:

1. First, determine the change in anion gap.
• The change in anion gap is given as: 43.
2. Next, determine the change in bicarbonate gap.
• The change in bicarbonate gap is provided as: 50.
3. Finally, calculate the Delta Ratio using the equation above:

DLR = AG / BG

The values given above are inserted into the equation below and the solution is calculated:

DLR = 43 / 50 = .86

Example Problem #2:

For this problem, the variables required are provided below:

change in anion gap = 70

change in bicarbonate gap = 300
