To Screen for Scarring Without a Procedure
Noninvasive tests are preferred for staging fibrosis, and a liver biopsy is kept for unclear cases. A score built from a scale, a blood panel, and your history is one of the simplest ways to start.
AI Summary The BARD score combines body mass index, the AST/ALT enzyme ratio, and diabetes status to estimate the risk of liver scarring (fibrosis) in people with fatty liver disease. It needs no scan or procedure. A lower score makes advanced fibrosis less likely, while a higher score usually leads to a second test, such as elastography or the ELF blood test. It cannot diagnose fibrosis or MASH. Next steps include follow-up testing, healthy habits, and specialist care.

BARD Score
Medically Reviewed.
The BARD score is a calculation that combines three everyday measures: body mass index (BMI), the ratio of two liver enzymes (AST and ALT), and whether you have diabetes. Doctors use it to estimate the chance of liver scarring, called fibrosis, in people with fatty liver disease.
It needs no scan and no procedure. It is a risk estimate, not a diagnosis. Your care team reads it alongside your other results and may suggest more testing.

UNDERSTANDING LIVER FIBROSIS RISK
What Is the BARD Score?
The BARD score is a noninvasive score that estimates how likely it is that your liver has fibrosis, or scar tissue. The name comes from its three parts: BMI, AST/ALT Ratio, and Diabetes.
Doctors use it in people with fatty liver disease. The current medical name is metabolic dysfunction-associated steatotic liver disease (MASLD). You may also see NAFLD, the older name. In MASLD, extra fat builds up in the liver. A more serious form, metabolic dysfunction-associated steatohepatitis (MASH, formerly NASH), adds inflammation, tissue damage, and scarring.
Fat alone often causes little harm. Scarring is what doctors most want to catch early. The BARD score helps them decide who may need a closer look.
AST and ALT are liver enzymes that rise when liver cells are injured. BARD does not measure liver fat directly. It is one of several MAFLD / MASH scores.
BARD Score at a Glance
- Combines three measures: BMI, the AST/ALT ratio, and diabetes status.
- Estimates the risk of liver scarring (fibrosis) in people with fatty liver disease.
- Needs no scan and no procedure, only your BMI, routine blood results, and your medical history.
- Blood-based scores are better at ruling out advanced fibrosis than at confirming it.
- Scores like this work best at separating advanced scarring (stage F3 or higher) from non-advanced scarring.
- A result points to the next step. It does not diagnose fibrosis or MASH.
BARD SCORE USES AND PURPOSE
Why Doctors Use the BARD Score
The BARD score answers one question: how likely is it that fatty liver disease has caused scarring? It is a triage tool, not an everyday liver test.
To Decide Who Needs a Closer Look
These tools help find people at risk for advanced liver disease who may need a specialist referral or close monitoring. People with obesity, type 2 diabetes, or high cholesterol are the ones most often scored.
To Guide the Next Test
A low score may mean no further testing is needed right now. A higher score usually leads to a second test, such as elastography (a liver stiffness scan) or a blood test like the ELF score.
BARD SCORE INPUTS EXPLAINED
What Goes Into the BARD Score
Each letter in BARD stands for one input. Your care team takes them from your chart, your BMI, and routine blood work.
- B: body mass index (BMI)
- BMI compares your weight with your height. A higher BMI reflects metabolic risk and fat buildup in the liver.
- AR: AST/ALT ratio
- AST and ALT are liver enzymes. Their balance helps show inflammation or liver injury. Both come from a standard blood test.
- D: diabetes
- Diabetes raises the risk of liver scarring. This input comes from your medical history.
Why the Inputs Are Simple
All three inputs are already part of routine care, so the score needs no extra procedure.
Your care team can tell you how your own result was worked out and how it fits with your other tests.
INTERPRETING YOUR SCORE
How to Read a BARD Result
Like other fibrosis scores, BARD sorts people by risk. It does not give a diagnosis.
A Lower Score
A lower score suggests advanced fibrosis is less likely. Blood-based scores tend to be most reliable for ruling out advanced fibrosis, so a low result can mean you do not need urgent extra testing. Your doctor may still suggest healthy habits and regular follow-up.
A Higher Score
A higher score suggests advanced fibrosis is more likely. It does not confirm scarring. It usually means your doctor will suggest a second test, such as elastography or the ELF blood test, and may refer you to a liver specialist.
If the Result Feels Unclear
Scores are less reliable at confirming scarring than at ruling it out. When results conflict or stay unclear, doctors can use another noninvasive test. A liver biopsy is considered when noninvasive results are ambiguous.
Ask About Your Exact Number
Scoring cutoffs can differ between sources. Ask your care team which cutoff they use and what it means for your next step.
FIBROSIS SCORE LIMITATIONS
What the BARD Score Cannot Tell You
It Cannot Diagnose Fibrosis or MASH
BARD estimates risk. Histology from a liver biopsy remains the gold standard for diagnosing MASH, the inflamed form of fatty liver. Your doctor combines imaging, lab tests, and your history.
It Does Not Measure Liver Fat or Stiffness
BARD uses BMI, enzymes, and diabetes status as indirect clues. Tests such as [elastography](/liver-tests/imaging-non-invasive-testing/elastography-fibrosis-testing) measure liver stiffness directly, and MRI-based tests measure liver fat.
Blood-Based Scores Can Miss Earlier Scarring
Scores such as FIB-4 and the NAFLD fibrosis score are most accurate at separating advanced fibrosis from non-advanced fibrosis. They perform poorly at identifying earlier stages of significant fibrosis. Ask your doctor how that applies to your BARD result.
FIBROSIS TEST COMPARISON
BARD Compared With Other Fibrosis Tests
Several tests estimate scarring. They use different inputs, and doctors often use more than one.
| Test | What it uses | Type |
|---|---|---|
| BARD score | BMI, AST/ALT ratio, diabetes | Calculated score, no procedure |
| FIB-4 | Age, AST, ALT, platelet count | Blood-based score |
| APRI | AST and platelet count | Blood-based score |
| ELF score | Hyaluronic acid, PIIINP, TIMP-1 | Blood test |
| Elastography (FibroScan) | Ultrasound-based liver stiffness | Imaging test |
| FAST score | FibroScan stiffness, FibroScan fat measure (CAP), AST | Score that combines imaging and blood |
FATTY LIVER FOLLOW-UP CARE
What to Do After Your Result
Your score is a starting point. These steps help you use it well.
Talk With Your Doctor About Follow-Up Testing
Ask whether you need a second test, such as elastography or the ELF blood test, and when to repeat your labs. Bring a list of your medicines and your diabetes history.
Focus on the Habits That Protect Your Liver
Lifestyle change is the foundation of fatty liver care. Weight loss of 3 to 5% can improve liver fat, and more than 10% is often needed to improve inflammation and scarring. A Mediterranean-style diet and regular exercise help too, even without weight loss.
Ask About Treatment if Scarring Is Likely
Medicines are mainly for people with biopsy-proven MASH or advanced fibrosis, and bariatric surgery may suit people who meet standard criteria. Your specialist can explain which options fit you.

Common Questions
Answers to Common BARD Score Questions
What does the BARD score stand for?
BARD stands for BMI, AST/ALT ratio, and Diabetes. These three inputs are combined into one score that estimates the risk of liver scarring (fibrosis) in people with fatty liver disease. BMI compares your weight with your height. AST and ALT are liver enzymes, and their ratio comes from a standard blood test. Diabetes status comes from your medical history. Your doctor uses the result to decide who may need a closer look, not to make a diagnosis.
Is the BARD score a diagnosis?
No. The BARD score estimates risk and helps your doctor choose the next step. It cannot diagnose fibrosis or MASH. Noninvasive tests are preferred for staging fibrosis, and a liver biopsy is kept for unclear cases. Histology from a biopsy remains the gold standard for diagnosing MASH. In practice, your doctor combines your score with imaging, other lab tests, and your history.
Does a low BARD score mean my liver is healthy?
Not always. A low score suggests advanced scarring is less likely, but it does not rule out every problem. Blood-based scores are most reliable at ruling out advanced fibrosis. Scores like this perform poorly at identifying earlier stages of significant fibrosis. BARD also does not measure liver fat directly. Keep up with regular checkups and healthy habits, and ask your doctor how often to repeat your labs.
Does a high BARD score mean I have cirrhosis?
No. A high score means advanced fibrosis is more likely and that more testing is wise. It does not confirm scarring. Cirrhosis is severe, permanent scarring, and a risk score cannot show that on its own. Blood-based scores are weaker at confirming scarring than at ruling it out. Your doctor will usually order a second test, such as elastography or the ELF blood test, and may refer you to a liver specialist.
Do I need to fast or have a special test for the BARD score?
No special procedure is needed. The score needs no scan and no biopsy. It uses your BMI, routine blood results (AST and ALT), and your diabetes status from your medical history. If your blood draw is ordered with other tests, there may be preparation for those tests. Ask your care team whether your blood draw has any preparation.
