What's this test for?

This test is ideal if you're at risk of fatty liver disease and want to know if it has progressed to liver scarring, called fibrosis. It's often used if you've been told you have a fatty liver, have risk factors like obesity, diabetes, or high cholesterol, or your prior liver blood work came back abnormal. This panel helps catch liver damage early, before it becomes serious, so you can take action while there's still time to reverse it.

What's included in this test?

This panel calculates the FIB-4 index using routine blood markers along with your age, which estimates how much scarring may be present in your liver. If that score comes back elevated, the lab automatically adds the Enhanced Liver Fibrosis (ELF) score, a more advanced marker set that gives a clearer read on fibrosis severity. Together, these two steps offer a stepwise, cost-effective way to catch liver damage without needing an invasive biopsy.

What happens after I get my results?

Your results will show up in your account with each value explained alongside its normal range, so you know exactly where you stand. If your FIB-4 score comes back elevated, the lab automatically runs the follow-up ELF score on the same sample, giving you a more complete picture without a second visit. Depending on what your results show, next steps might include lifestyle changes like reducing alcohol, losing weight, or adjusting your diet, plus a retest in 6-12 months to track progress. You can download the full lab report anytime and use the trends feature to watch your liver health numbers change over time.

How can I naturally support liver health?
Cutting back on alcohol, sugar, and processed foods can significantly reduce stress on your liver. Regular exercise and gradual weight loss (even 5-10% of body weight) have been shown to improve fatty liver and reduce scarring risk. Foods like leafy greens, coffee (in moderation), and omega-3 rich fish may also support liver function. If your numbers stay high despite these changes, it's a sign to look deeper into what's driving the damage.
When will I get my results?
Results are typically ready within about 7 days of your blood draw. If your FIB-4 score triggers the reflex ELF test, that additional processing is included in the same turnaround window, so you won't need a separate appointment. You'll get a notification as soon as your full results, including any reflex testing, are available in your account.
Who should consider this test?
This test is a good fit if you have risk factors for fatty liver disease, such as obesity, type 2 diabetes, high triglycerides, or a history of heavy alcohol use. It's also useful if you've had abnormal liver enzyme results in the past and want to understand what's causing them. People with a family history of liver disease may also benefit from establishing a baseline.
What symptoms indicate I may need this test?
Fatty liver disease often has no symptoms in its early stages, which is why screening matters even if you feel fine. Some people notice mild fatigue, discomfort in the upper right side of the belly, or unexplained weight changes. If you've been told your liver enzymes are elevated on routine blood work, that's another strong signal to check further.
What is liver fibrosis and why does it matter?
Liver fibrosis is scarring that builds up in the liver over time, usually from ongoing inflammation or fat buildup. In its early stages, fibrosis can often be slowed or even reversed with lifestyle changes, but if it progresses too far, it can lead to serious, permanent liver damage called cirrhosis. Catching it early with a simple blood-based score gives you the best chance to protect your liver long-term.
What does a high FIB-4 score mean?
A high FIB-4 score suggests there may be a meaningful amount of scarring in your liver and warrants a closer look, which is why the ELF score is automatically added when this happens. It doesn't mean the damage is permanent, especially if caught early. This is a good time to focus on reducing alcohol, improving your diet, and losing weight if needed, and to retest to track your progress.
How often should I retest?
If your first results are normal, retesting once a year is usually reasonable if your risk factors stay the same. If your FIB-4 or ELF score comes back elevated, retesting every 6-12 months after making lifestyle changes can help you see whether your liver health is improving. Tracking your numbers over time is one of the best ways to know if your efforts are working.

FIB-4 Index Score 1.65
Demo results
Low Risk (<1.30) Elevated Risk (≥1.30)
1.65

What this means

A FIB-4 score of 1.65 falls above the 1.30 threshold, which means there may be meaningful liver scarring present. Because this score is elevated, the ELF score will automatically be run on the same sample for a clearer picture.

* 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.
