The ALT/AST Ratio Calculator helps determine the ratio of AST to ALT in the blood, an important metric in assessing liver conditions such as cirrhosis and hepatitis. By inputting individual ALT and AST values, this tool calculates their ratio, offering immediate insights into potential health issues.
Formula of ALT/AST Ratio Calculator
The formula for calculating the ALT (Alanine Aminotransferase) to AST (Aspartate Aminotransferase) ratio is straightforward:
AST / ALT = ratio
A ratio greater than 1 often indicates cirrhosis, a condition characterized by the replacement of liver tissue with scar tissue. A ratio exceeding 2 typically points to alcoholic hepatitis, which is inflammation caused by excessive alcohol consumption. Low levels of these enzymes might indicate issues beyond the liver, such as muscle or thyroid gland diseases.
Table for General Terms
This table outlines typical ALT and AST values and what they might suggest about an individual’s liver health:
| ALT Level (U/L) | AST Level (U/L) | ALT/AST Ratio | Possible Health Implication |
|---|---|---|---|
| 50 | 30 | 1.67 | Normal or slightly elevated |
| 70 | 120 | 0.58 | Possible liver injury |
| 35 | 80 | 0.44 | Check for non-liver issues |
Use this table to understand possible health implications without performing calculations manually.
Example of ALT/AST Ratio Calculator
Consider a patient with an ALT of 72 U/L and an AST of 144 U/L. The calculator would determine:
AST / ALT = 144 / 72 = 2
This ratio suggests a strong likelihood of alcoholic hepatitis and warrants further medical investigation.
Most Common FAQs
A ratio over 1 often suggests liver conditions like cirrhosis, reflecting significant liver damage.
Yes, a ratio greater than 2 is highly indicative of damage from alcohol, such as alcoholic hepatitis.
The frequency depends on the underlying health conditions and should be determined by a healthcare provider.
