Enter the AST enzymes (U/L) and the ALT enzymes (U/L) into the Calculator. The calculator will evaluate the Ast Ratio.

## Ast Ratio Formula

AR = AST / ALT

Variables:

- AR is the Ast Ratio ()
- AST is the AST enzymes (U/L)
- ALT is the ALT enzymes (U/L)

To calculate Ast Ratio, divide the AST enzymes by the ALT enzymes.

## How to Calculate Ast Ratio?

The following steps outline how to calculate the Ast Ratio.

- First, determine the AST enzymes (U/L).
- Next, determine the ALT enzymes (U/L).
- Next, gather the formula from above = AR = AST / ALT.
- Finally, calculate the Ast Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

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

AST enzymes (U/L) = 20

ALT enzymes (U/L) = 40
