## 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

## How to Calculate Delta Ratio?

The following example problems outline how to calculate Delta Ratio.

Example Problem #1:

- First, determine the change in anion gap.
- The change in anion gap is given as: 43.

- Next, determine the change in bicarbonate gap.
- The change in bicarbonate gap is provided as: 50.

- 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

Test your knowledge using the equation and check your answer with the calculator above.

DLR = AG / BG** = ?**
