What Ast Alt Ratio Calculator does
The Ast Alt Ratio Calculator on Calculator Academy determines the De Ritis ratio by dividing a user's AST enzyme value by their ALT enzyme value. Users input their AST and ALT levels in units per liter (U/L), international units per liter (IU/L), or microkat per liter (µkat/L), and the tool instantly outputs the unitless ratio. The result includes a basic interpretation of the liver pattern, and the calculator automatically handles unit conversions so users do not need to manually normalize their lab values before entering them. An educational medical disclaimer is also provided alongside the output. The Calculator Academy version distinguishes itself by supporting three common lab units (U/L, IU/L, and µkat/L) and performing automatic conversions, whereas many competing tools require inputs in a single unit. The interface is minimal and formula-focused, presenting the De Ritis ratio equation and a step-by-step calculation guide directly on the page. Additionally, the site offers an embed code, allowing the calculator to be integrated into other websites, a feature not universally available among the listed alternatives.

Best for
This option suits clinicians, students, or patients who need a quick, unit-flexible way to compute the AST/ALT ratio and understand basic liver enzyme patterns without manual conversion.
Limitations
- Results are estimates and not a medical diagnosis
- The tool provides a basic interpretation only, not a full clinical assessment
- No option to save or export calculation history within the page
Ast Alt Ratio Calculator FAQ
- Can I use AST and ALT values from different units, such as U/L for AST and IU/L for ALT?
- Yes, the Calculator Academy calculator automatically converts between U/L, IU/L, and µkat/L, so you can input values in whichever units your lab report uses without needing to manually convert them first.
- What does a high or low AST/ALT ratio indicate?
- A ratio greater than 2:1 often suggests alcoholic liver disease, while a ratio less than 1:1 is more typical of non-alcoholic causes; however, the result should always be interpreted by a healthcare provider in the context of other findings.
- Is the calculated ratio a diagnosis for liver disease?
- No, the tool provides a mathematical ratio and a general pattern interpretation only; it is not a substitute for professional medical evaluation or diagnostic testing.
- Can I embed this calculator on my own website?
- Yes, Calculator Academy provides an embed code with attribution that can be copied and pasted into a website to display the Ast Alt Ratio Calculator.
