Fatty liver: blood test panels may soon spare some people a biopsy

If you have fatty liver, there may soon be a way to check how your liver is doing without a needle biopsy. A large study found that some blood test panels can spot serious liver scarring quite well, and the best one was a protein panel.
The names are technical, but the idea is simple. Doctors want to find the people whose liver is in trouble, and leave everyone else alone. Fatty liver is very common. Most people with it never get seriously ill, but a few develop scarring. Now that approved medicines exist, finding those few matters more.
How the study worked
Researchers in 13 countries across Europe and the USA followed 1,590 adults who already had fatty liver confirmed by biopsy. They compared 12 single tests and 18 combined panels against the biopsy results, which experts scored. The study was published Oct. 31, 2026, in The Lancet. Because everyone had already been sent for a biopsy, results in a regular checkup setting could look different.
What they found
The researchers set a bar for how well a test had to perform to be considered good enough to possibly replace a biopsy.
Combined panels did best. Single tests were mixed and often not strong enough on their own.
- Liver in trouble (inflammation plus scarring): a protein panel called SomaSignal was the only test to clear the bar.
- Advanced scarring: SomaSignal came out on top. FibroMeter-VCTE came next, then Agile 3+ and TSP2, and then NIS4.
- Cirrhosis (the most severe scarring): FibroMeter-VCTE led, followed by SomaSignal, Agile 3+ and Agile 4.
There was one more useful result. A two-step approach that starts with a common liver enzyme blood test, called gamma-glutamyl transferase (GGT), met the bar for both advanced scarring and liver in trouble. That means a routine, inexpensive test can be a good first step.
What does the alphabet soup mean?
MASLD is the new medical name for fatty liver linked to extra weight, diabetes or high cholesterol. MASH is the version with inflammation. Fibrosis is scarring. Cirrhosis is advanced scarring. The tests above are simply different ways of measuring those things, using blood or a scan.
What you can do today
If you have type 2 diabetes, extra weight or past liver tests that were off, pull up your latest blood work in your patient portal. Look for the liver enzymes (often listed as ALT, AST or GGT). Then ask at your next visit whether a simple fibrosis check, such as a blood score or a liver stiffness scan, makes sense for you.
Talk about it at home
The liver is like a busy kitchen in your body, and the blood is the road that carries little clues out of it. Scientists tested many blood clues to see which ones told the same story as the careful way of looking closely at the liver. They used a very large group of grown-ups so the answer would not depend on just a few people.
Question for the table
Why do you think the scientists checked each new blood test against the older, careful method instead of just trusting the new one?

Questions and answers
- What is MASLD?
- It is the new name for fatty liver disease linked to extra weight, diabetes or high cholesterol.
- Which tests worked best?
- Combined panels. A protein panel called SomaSignal scored highest for advanced scarring, and FibroMeter-VCTE scored highest for cirrhosis.
- Can these tests replace a biopsy?
- Some came close. Only one panel clearly cleared the study's bar for liver inflammation plus scarring, so biopsy still has a role.
- What is the GGT test?
- It is a common liver enzyme blood test. Used as a first step, it helped the two-step approach work well.
