AST to ALT Ratio Calculator

Formula

To calculate the AST to ALT Ratio (AST/ALT):

\[ AST/ALT = \frac{AST}{ALT} \]

Where:

\(AST/ALT\) is the AST to ALT Ratio
\(AST\) is the aspartate aminotransferase level (U/L)
\(ALT\) is the alanine aminotransferase level (U/L)

What is the AST to ALT Ratio?

The AST to ALT Ratio (AST/ALT) is a measure used to assess liver function. It is calculated by dividing the AST level by the ALT level. This ratio can help differentiate between various liver conditions, such as alcoholic liver disease and non-alcoholic fatty liver disease[^1^][^2^].

Example Calculation 1

Let's assume the following values:

AST (\(AST\)) = 40 U/L
ALT (\(ALT\)) = 20 U/L

Using the formula:

\[ AST/ALT = \frac{40}{20} = 2 \]

The AST to ALT Ratio is 2.

Example Calculation 2

Let's assume the following values:

AST (\(AST\)) = 30 U/L
ALT (\(ALT\)) = 15 U/L

Using the formula:

\[ AST/ALT = \frac{30}{15} = 2 \]

The AST to ALT Ratio is 2.
