What's this test for?

This test is ideal if you're trying to understand whether recent drinking habits might be affecting your body, or if you need documentation of alcohol use over the past couple of weeks. It helps if you have concerns about liver health, are monitoring your own alcohol consumption, or need to confirm heavy drinking patterns for personal, legal, or workplace reasons. It's also useful if you have unexplained liver symptoms and want to rule out alcohol as a contributing factor.

What's included in this test?

This test measures a single, specific marker in your blood that reflects a pattern of heavy alcohol consumption over roughly the past two weeks. It's different from general liver enzyme tests because it's more specific to alcohol use rather than general liver stress, making it useful when alcohol intake itself is the main question.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus elevated range looks like for this test. If your level comes back high, practical next steps include cutting back or stopping alcohol intake, giving your body a few weeks to reset, and retesting to see if the level drops. A full downloadable lab report is available in your account, and you can use the trends feature to track your levels over time as you make changes.

How can I naturally support liver health?

Cutting back on alcohol is the single most effective step, since your liver needs time without alcohol to repair itself. Eating a diet rich in vegetables, lean protein, and whole grains while limiting processed and fatty foods also supports liver function. Staying hydrated, getting regular exercise, and avoiding unnecessary medications or supplements that stress the liver can help too. Milk thistle and certain antioxidants are sometimes used by people looking for extra support, but consistent lifestyle changes matter most.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected at the lab. Once ready, they'll be posted directly to your online account where you can view and download them at your convenience.

Who should consider this test?

This test is a good fit for anyone who wants an objective look at recent alcohol consumption, including people who are cutting back on drinking and want to track progress, or those with liver concerns who want to understand if alcohol is a factor. It's also useful for people who need documentation of drinking patterns for personal accountability or other formal reasons.

What symptoms indicate I may need this test?

Signs like fatigue, abdominal discomfort, yellowing skin or eyes, or unexplained changes in liver-related blood work can be reasons to consider this test, especially if alcohol use is part of the picture. If you've noticed increased tolerance to alcohol, difficulty cutting back, or physical symptoms after drinking, this test can offer useful information.

What does a high result mean?

A high result suggests a pattern of heavy alcohol use, generally more than 4 to 5 drinks per day over two or more weeks. It can also occasionally be elevated due to certain liver conditions or a rare genetic variant of the transferrin protein, so a high number alone doesn't automatically confirm heavy drinking. Cutting back on alcohol and retesting after a few weeks can help clarify what's driving an elevated result.

What causes an elevated result besides alcohol?

While heavy drinking is the most common cause, certain liver diseases such as primary biliary cirrhosis or chronic active hepatitis can also raise this marker. A less common cause is a genetic variant of the transferrin protein itself, which isn't related to alcohol at all. If your result is high and you don't drink heavily, it may be worth looking into these other possibilities.

How often should I retest?

If you're actively cutting back on alcohol, retesting every few weeks can help you see whether your levels are trending down. Since this marker reflects roughly a two-week window of drinking behavior, waiting at least that long between tests gives a more accurate picture of change. Regular retesting can also help confirm whether an elevated result was alcohol-related or due to another cause.
