The NAFLD Fibrosis Score Calculator is a clinical tool that estimates the risk of advanced liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) using readily available clinical and laboratory data. It aids in the assessment and management of NAFLD patients' liver health.
What is NAFLD Fibrosis Score Calculator
The NAFLD Fibrosis Score Calculator used to assess the likelihood of significant fibrosis in patients with Non-Alcoholic Fatty Liver Disease (NAFLD).
- It combines six readily available clinical and laboratory parameters, including age, BMI, presence of diabetes, platelet count, albumin level, and AST/ALT ratio, to calculate a numerical score.
- The score ranges from -1.455 to 2.110 and is used to categorize patients into low, intermediate, and high-risk groups for significant fibrosis.
- The NAFLD Fibrosis Score Calculator aids healthcare professionals in identifying patients who may require further evaluation or liver biopsy for fibrosis assessment.
How to Calculate NAFLD Fibrosis Score
Here are the basic steps to calculate NAFLD Fibrosis Score.
- Enter Your Age, Height and Weight
- Verify Your IFG or diabetes
- Enter Your AST and ALT Levels
- Enter Platelet Count and Albumin Level
- Calculate NAFLD Fibrosis Score
What is Non-alcoholic fatty liver disease (NAFLD)
Non-alcoholic fatty liver disease (NAFLD) is a liver condition characterized by excessive fat accumulation in the liver cells.
- It is not caused by alcohol consumption, and the exact cause is often related to factors like obesity, insulin resistance, and metabolic syndrome.
- NAFLD can range from simple fatty liver (steatosis) to non-alcoholic steatohepatitis (NASH), which involves inflammation and liver damage.
- If left untreated, NAFLD can progress to advanced liver conditions, such as fibrosis, cirrhosis, and even liver cancer.
- Lifestyle modifications, such as weight loss, balanced diet, regular exercise, and managing underlying conditions, are key to managing NAFLD.
- Regular medical check-ups and monitoring are essential for detecting any progression or complications of NAFLD.
Risk Factors of NAFLD
Here are the risk factors of Non-alcoholic Fatty Liver Disease (NAFLD).
- Obesity or overweight
- Insulin resistance or type 2 diabetes
- High blood pressure (hypertension)
- High levels of triglycerides or low levels of high-density lipoprotein (HDL) cholesterol
- Metabolic syndrome
- Sedentary lifestyle or lack of physical activity
- Unhealthy diet high in saturated fats and sugars
- Older age
- Certain genetic factors and family history of NAFLD
- Polycystic ovary syndrome (PCOS) in women
- Sleep apnea
- Certain medications, such as corticosteroids and some anti-cancer drugs
It's important to note that having one or more of these risk factors doesn't necessarily mean a person will develop NAFLD, but they may increase the likelihood of its occurrence.
NAFLD Fibrosis Score
The NAFLD fibrosis score is a non-invasive tool used to assess the risk of liver fibrosis in patients with Non-alcoholic Fatty Liver Disease (NAFLD).
- The score is based on a formula that incorporates six variables: age, body mass index (BMI), presence of diabetes, platelet count, albumin levels, and aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio.
- The NAFLD fibrosis score can assist healthcare professionals in identifying the severity of liver fibrosis in NAFLD patients without the need for a liver biopsy, offering a non-invasive and practical approach to assess liver health.
NAFLD fibrosis score calculator uses the following formula to compute the NAFLD fibrosis score:
NFS = -1.675 + (0.037 × age) + (0.094 × BMI) + (1.13 × hyperglycemia) + (0.99 × AST/ALT ratio) - (0.013 × platelet count) - (0.66 × albumin)
where:
- NFS - NAFLD fibrosis score;
- Age - age expressed in years;
- BMI - Body Mass Index expressed in kg/m² (the NAFLD fibrosis score calculator calculates it for you);
- Hyperglycemia - presence of impaired fasting glucose or diabetes (yes = 1, no = 0);
- AST/ALT ratio - AST and ALT levels expressed in IU/L (the NAFLD fibrosis score calculator calculates AST/ALT ratio for you);
- Platelet count - platelet count expressed in 10⁹/L; and
- Albumin - albumin level expressed in g/dL (the NAFLD fibrosis score calculator can also convert it from g/L).
NAFLD fibrosis score range
The following NAFLD fibrosis score range is used to identify liver fibrosis:
| NAFLD Fibrosis Score |
Interpretation |
| Less than -1.455 |
Low probability of fibrosis |
| From -1.455 to 0.676 |
Intermediate score |
| More than 0.676 |
High probability of fibrosis at baseline |
