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.

1. First, determine the AST enzymes (U/L). 
2. Next, determine the ALT enzymes (U/L). 
3. Next, gather the formula from above = AR = AST / ALT.
4. Finally, calculate the Ast Ratio.
5. 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

FAQs

What is the significance of the AST/ALT ratio in medical diagnostics?

The AST/ALT ratio is an important indicator in medical diagnostics used to evaluate liver health. A ratio greater than 1 can indicate liver disease, such as alcoholic liver disease, while a lower ratio may suggest non-alcoholic fatty liver disease.

Can the AST/ALT ratio be used to diagnose specific liver conditions?

While the AST/ALT ratio can provide clues about liver health and the nature of liver damage, it is not specific enough to diagnose particular liver conditions without additional tests and clinical evaluation.

How often should the AST/ALT ratio be checked in individuals with known liver disease?

The frequency of AST/ALT ratio testing in individuals with liver disease depends on the specific condition, its severity, and the treatment plan. Doctors typically recommend regular monitoring to assess liver function and the effectiveness of treatment.

Are there any factors that can affect the accuracy of AST/ALT ratio calculations?

Yes, several factors can affect the accuracy of AST/ALT ratio calculations, including recent alcohol consumption, use of certain medications, and the presence of muscle damage. It is important to consider these factors when interpreting the results.
