What's this test for?

This test is ideal if you're concerned about liver damage from fatty liver disease, heavy alcohol use, hepatitis, or long-term health conditions like diabetes. It helps if you have risk factors for liver scarring but no obvious symptoms yet, since early liver fibrosis often has no warning signs. This panel gives you a simple risk score for advanced liver scarring using a blood-based calculation.

What's included in this test?

This panel combines a few key liver-related blood measurements with your age to calculate a fibrosis risk score. The individual measurements reflect how well your liver cells are functioning and whether your blood's clotting-related cell count is in a healthy range, both of which shift when liver scarring develops.

What happens after I get my results?

Your results, including the FIB-4 score and each individual value, will appear in your account with the normal ranges explained in plain language. If your score suggests higher risk, next steps usually include lifestyle changes like reducing alcohol intake, improving diet, and losing excess weight, plus retesting in a few months to track change. If any value comes back at a dangerously abnormal level, seek medical care right away. You can download the full lab report from your account anytime, and use the trends feature to watch your liver health numbers over time.

How can I naturally support liver health?
Cutting back on alcohol, added sugar, and fried or processed foods can take real pressure off your liver. Regular exercise and gradual weight loss, if you carry extra weight, are some of the most effective ways to reduce fatty buildup in the liver. Coffee (in moderation) and foods rich in fiber, like vegetables and whole grains, have also been linked to better liver health markers.
When will I get my results?
Results are typically ready within about 7 days of your blood draw. You'll get a notification and can log into your account to view and download your report as soon as it's available.
Who should consider this test?
This test is a good fit for people with fatty liver disease, type 2 diabetes, obesity, high cholesterol, or a history of heavy alcohol use. It's also worth considering if you have chronic hepatitis B or C, or if past blood work showed elevated liver enzymes. Anyone with a family history of liver disease may also want this as a baseline check.
What symptoms indicate I may need this test?
Liver scarring often causes no symptoms in its early stages, which is exactly why this test is useful. That said, fatigue, mild abdominal discomfort on the right side, unexplained weight loss, or yellowing of the skin or eyes are signs worth checking out. Swelling in the legs or belly can also be a later-stage symptom worth investigating.
What is liver fibrosis and why does it matter?
Liver fibrosis is scarring of the liver that happens when the organ is repeatedly damaged or inflamed over time, often from fat buildup, alcohol, or viral infection. Early scarring can often be slowed or even reversed with lifestyle changes, but advanced scarring (cirrhosis) can lead to serious, permanent liver problems. Catching it early gives you the best chance to protect your liver long-term.
What does a high FIB-4 score mean?
A high score suggests a greater chance of advanced liver scarring and means it's worth taking liver health seriously through lifestyle changes and closer monitoring. It doesn't mean you definitely have advanced fibrosis, but it flags you as someone who should retest and track your numbers over time. Cutting alcohol, managing weight, and controlling blood sugar are practical first steps.
How often should I retest?
If your score is in the normal range and you have no major risk factors, checking every 1-2 years is generally reasonable. If your score is elevated or you're actively making lifestyle changes, retesting every 3-6 months can help you see if those changes are working. Tracking results over time through the trends feature makes it easier to spot meaningful shifts.

FIB-4 Index Score 1.8
Demo results
Low Risk (<1.3) Indeterminate (1.3-2.67) High Risk (>2.67)
1.8

What this means

A FIB-4 score of 1.8 falls in the indeterminate zone, meaning advanced liver scarring can't be ruled out but isn't strongly indicated either. This is a signal to pay closer attention to liver health and consider lifestyle changes and retesting rather than a definitive diagnosis.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
