AST/ALT Ratio Calculator

Formula

To calculate the AST/ALT Ratio (R):

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

Where:

\(R\) is the AST/ALT ratio
\(AST\) is the Aspartate Aminotransferase level (U/L)
\(ALT\) is the Alanine Aminotransferase level (U/L)

What is AST/ALT Ratio?

The AST/ALT ratio is a biomarker used in the diagnosis and monitoring of liver diseases. It is calculated by dividing the level of AST by the level of ALT in the blood. This ratio can help differentiate between various liver conditions.

Example Calculation 1

Let's assume the following values:

AST Level = 40 U/L
ALT Level = 20 U/L

Using the formula:

\[ R = \frac{40}{20} = 2 \]

The AST/ALT ratio is 2.

Example Calculation 2

Let's assume the following values:

AST Level = 60 U/L
ALT Level = 30 U/L

Using the formula:

\[ R = \frac{60}{30} = 2 \]

The AST/ALT ratio is 2.
