When people drink at harmful levels, liver cells are killed. The contents of the cells are released into the blood, increasing the GGT level measured in the blood test. If your result is higher than the normal range, it means that your liver is being harmed.
How long will liver enzymes stay elevated after drinking?
Levels typically rise after heavy alcohol intake that has continued for several weeks (Allen et al. 1994). With 2–6 weeks of abstinence, levels generally decrease to within the normal reference range, with the half–life of GGT being 14–26 days.
How long should I abstain from alcohol before a liver function test?
Some blood tests, such as those that assess liver health or triglyceride levels, may require you to not drink any alcohol for a full 24 hours. Trace amounts of alcohol can remain in your bloodstream for several days.
Can drinking alcohol cause elevated liver enzymes?
Alcohol use markedly increases the risk for abnormal liver enzyme activities in those presenting with age over 40 years, obesity, smoking or sedentary lifestyle.
Can an alcoholic have normal liver function tests?
There are usually no symptoms. If symptoms do occur, they may include fatigue, weakness, and discomfort in the upper-right abdomen. Liver enzymes may be elevated, but tests of liver function are often normal. Many heavy drinkers have fatty liver disease.
Is 70 a high ALT level?
Normal levels of AST and ALT may slightly vary depending on the individual laboratory’s reference values. Typically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter. Mild elevations are generally considered to be 2-3 times higher than the normal range.
What liver tests show alcohol damage?
Liver disease is the most likely diagnosis if the AST level is more than twice that of ALT (9), a ratio some studies have found in more than 80 percent of alcoholic liver disease patients. An elevated level of the liver enzyme GGT is another gauge of heavy alcohol use and liver injury.
Can one night of heavy drinking raise liver enzymes?
Next Looking to Longer-Term Impacts on Liver
The researchers also found that even a single episode of binge drinking elevated the levels of the liver enzyme CYP2E1, which metabolizes alcohol into toxic by-products that can cause oxidative damage and other forms of tissue injury.
Can a blood test show heavy drinking?
Blood tests can help to identify excessive alcohol use and possible liver damage. These tests have a low sensitivity and therefore should be used only to confirm suspected alcohol problems, not as a sole screening test. Blood tests can also be used to monitor changes in patients’ alcohol consumption.
How long should you abstain from alcohol before a blood test?
Some recent guidelines suggest that fasting is not necessary before all cholesterol and triglyceride tests. However, people who are having these tests should refrain from drinking alcohol for 24 hours before the test.
What are the first signs of liver damage from alcohol?

- decreased appetite.
What happens when your liver Cannot break down alcohol?
The liver cannot easily filter out large amounts of alcohol, which means that it needs to overwork in order to process the alcohol in the body. Overworking the liver results in an accumulation of fatty tissue, inflammation, and eventually significant scarring on the liver.
How serious is elevated liver enzymes?
In most cases, liver enzyme levels are only mildly and temporarily elevated. Most of the time, elevated liver enzymes don’t signal a chronic, serious liver problem.

- anemia (low blood levels due to too little iron)
- high blood ammonia level.
- high blood sugar levels.
- leukocytosis (large amount of white blood cells)
- unhealthy liver tissue when a sample is removed from a biopsy and studied in a laboratory.
Do all heavy drinkers have fatty liver?
About 20 percent of alcoholics and heavy drinkers develop fatty liver, or steatosis. In many cases there are no clinical symptoms except for an enlarged liver (hepatomegaly).
