How long should you abstain from alcohol before a liver function test?

To obtain accurate liver function test results, it is generally recommended to abstain from alcohol for at least 48 hours before the test. Alcohol consumption can temporarily elevate liver enzyme levels, including ALT and AST, making it difficult to assess the baseline liver function. Abstaining from alcohol allows the liver enzyme levels to normalize and provides a more accurate assessment of liver health. However, it's important to note that the duration of alcohol abstinence may vary depending on the individual's specific circumstances, the amount and frequency of alcohol consumption, and the advice of the healthcare professional. It's always recommended to follow the specific instructions provided by the healthcare provider regarding alcohol abstinence before liver function testing.
