Use our AST/ALT Ratio Calculator to quickly assess your liver health. This tool helps estimate liver function instantly, providing accurate results and saving you valuable time.

How the AST/ALT Calculator Works:

Using our AST/ALT calculator is simple and straightforward. Just follow these steps:

Enter your AST and ALT values in the provided fields
Select the correct units for each value
Click on Calculate

After calculation, the tool provides:

Your AST/ALT ratio
Potential risk of liver disease
Insights into the AST and ALT levels you provided

What Are AST and ALT?

AST (Aspartate Aminotransferase) and ALT (Alanine Aminotransferase) are enzymes primarily found in the liver. The levels of these enzymes in your blood indicate your liver’s health:

High levels of both AST and ALT may indicate liver damage or disease
Monitoring these values can help in early detection of liver problems

Regular use of the AST/ALT ratio calculator can help you stay informed about your liver function and guide decisions regarding treatment or lifestyle changes.

AST/ALT Ratio Chart:

Compare your results with the normal ranges below to understand your liver health better:

Enzyme	Normal Range
AST (SGOT)	5 – 40 units per liter of serum
ALT (SGPT)	7 – 56 units per liter of serum

Maintaining awareness of your AST and ALT levels is crucial for liver health. Use this calculator regularly to track your liver function and identify potential issues early.

How To Calculate ALT/AST Ratio?

To manually calculate this ratio, you can use the following formula:

AST / ALT = Ratio

Our ALT/AST ratio calculator also uses the same formula to quickly inform you if your liver may be at risk of any disease.

Example:

The AST and ALT values noted in a liver test of a patient are 25 and 13, respectively. Here's how to calculate the AST/ALT ratio:

Solution:

AST / ALT = 25 / 13 = 1.923

Although the AST and ALT values are within the normal range, the ratio is outside the safe region. This indicates the patient may be at high risk of Cirrhosis, and consulting a physician is advised.

AST/ALT Ratio Predictions:

High AST/ALT Values & AST/ALT Ratio	Possible Condition
AST/ALT Ratio > 1	Cirrhosis (Scar tissue formation – may lead to liver function failure)
AST/ALT Ratio > 2	Alcoholic Hepatitis (Inflammation of the liver due to regular alcohol consumption)
High AST/ALT Values & Low AST/ALT Ratio	Possible Cause
Low Ratio	Hemolysis (Breakdown of red blood cells), thyroid gland disease
Very Low AST/ALT Values	Possible Condition
Destruction of the liver	Caused by drug intake – e.g., Paracetamol
Hepatitis B & C	Viral infections of the liver that may be fatal
Non-alcoholic Steatohepatitis	Liver inflammation not caused by alcohol consumption
Autoimmune hepatitis	When the body attacks its own liver cells

FAQs:

When Should I Take the AST/ALT Ratio Test?

Stop eating at least 10–12 hours before giving a blood sample
Try to give a sample between 7–10 AM

With this AST/ALT ratio calculator, you can also check your liver health anytime, without restrictions.

What Is the SGOT/SGPT Ratio?

SGOT/SGPT is another term used for AST/ALT. You can use our calculator to calculate the SGOT/SGPT ratio and check for potential liver issues.

Why Is the AST/ALT Ratio Important?

The AST/ALT ratio is useful for:

Differentiating between alcoholic and non-alcoholic liver diseases
Detecting liver inflammation or potential liver failure
