How to use this tool
To use the Emerald liver risk score you will need the following blood tests: AST, ALT and platelets. These are available through Emerald and other providers. If you have had these blood tests before you can input your results here.
AST: Aspartate aminotransferase (AST) is an enzyme found in the liver, heart, and muscles.
ALT: Alanine aminotransferase (ALT) is an enzyme found in the liver that helps metabolise proteins.
Platelet count: Platelets are cells that help with blood clotting to prevent excessive bleeding.

What is the Liver Risk Score?
The Emerald Liver Risk Score is based on the FIB-4 Index, a validated medical tool that is widely used by clinicians. The Fibrosis-4 (FIB-4) Index is a non-invasive scoring system based on several laboratory tests that help to estimate the amount of scarring in the liver. This score uses blood results and demographic data to calculate your risk of liver fibrosis.
Liver fibrosis is the formation of scar tissue in the liver that can occur when the liver is repeatedly injured or inflamed over time. This can happen due to various conditions including fatty liver disease, viral hepatitis, or excessive alcohol consumption. The blood test markers used in the calculation can indicate when this scarring process may be occurring, even before symptoms appear.

Understanding Your Score
Your Liver Risk Score falls into one of three categories, each designed to guide your next steps:
Low Risk (Score below 1.3) A score in this range indicates a low likelihood of advanced liver fibrosis. Studies show that FIB-4 scores less than 1.45 have a 90% negative predictive value for advanced fibrosis. This means that if your score falls in this range, there's a very high probability that you don't have established liver scarring. However, this doesn't guarantee perfect liver health, and maintaining healthy lifestyle habits remains important for ongoing liver wellness.
Intermediate Risk (Score 1.3 to 2.67) A score in this range means the test cannot definitively determine your risk level, and additional testing or monitoring would be helpful to get a clearer picture. This doesn't indicate immediate concern, but it suggests that more detailed assessment with specialised tests or imaging might be beneficial.
Higher Risk (Score above 2.67) If your score falls in this category, there's a higher likelihood of significant liver scarring, and consultation with a doctor or additional imaging studies (such as an ultrasound) would be recommended to determine the best path forward for your health.

The Strengths and Limitations of the Score
Like any medical assessment tool, the Liver Risk Score has both strengths and limitations that are important to understand.
The score's strength is its simplicity and accessibility - it uses information routinely collected in standard blood work, meaning no additional tests or procedures are needed. The FIB-4 Index has been validated across different populations and liver conditions, with research showing it to be particularly reliable at identifying people who are at low risk for advanced liver scarring.
However, studies have demonstrated important limitations. The accuracy rate of FIB-4 for diagnosing established fibrosis is approximately 80%, which means about 20% of results may be incorrect. Additionally, certain factors can influence the accuracy of the score, including medications, other health conditions, or temporary illnesses that can affect liver enzyme levels or platelet counts.

What Influences Your Liver Health?
Understanding the factors that affect liver health can help you make informed decisions about your wellbeing. Some of the most significant influences include:
Alcohol consumption is one of the most direct factors affecting liver health. Your liver processes virtually all the alcohol you consume, and excessive drinking over time can lead to inflammation and scarring. The good news is that the liver has remarkable healing abilities when given the chance.
Diet and weight management play crucial roles in liver health. A diet high in processed foods, sugar, and unhealthy fats can contribute to fatty liver disease, while a balanced diet rich in vegetables, whole grains, and lean proteins supports optimal liver function. Increased weight and obesity is also linked to fatty liver.
Medications and supplements, even over-the-counter ones, are processed by your liver. Always inform your healthcare providers about everything you're taking, including herbal supplements, as some can affect liver function.
Viral infections like hepatitis B and C can cause ongoing liver inflammation, if you have been exposed or tested positive.
Metabolic conditions such as diabetes and high cholesterol are closely linked with liver health, as the liver plays a central role in processing fats and sugars.

Understanding Your Score
Your Liver Risk Score falls into one of three categories, each designed to guide your next steps:
Low Risk (Score below 1.3) A score in this range indicates a low likelihood of advanced liver fibrosis. Studies show that FIB-4 scores less than 1.45 have a 90% negative predictive value for advanced fibrosis. This means that if your score falls in this range, there's a very high probability that you don't have established liver scarring. However, this doesn't guarantee perfect liver health, and maintaining healthy lifestyle habits remains important for ongoing liver wellness.
Intermediate Risk (Score 1.3 to 2.67) A score in this range means the test cannot definitively determine your risk level, and additional testing or monitoring would be helpful to get a clearer picture. This doesn't indicate immediate concern, but it suggests that more detailed assessment with specialised tests or imaging might be beneficial.
Higher Risk (Score above 2.67) If your score falls in this category, there's a higher likelihood of significant liver scarring, and consultation with a doctor or additional imaging studies (such as an ultrasound) would be recommended to determine the best path forward for your health.

Like any medical assessment tool, the Liver Risk Score has both strengths and limitations that are important to understand.

The FIB-4 Index has been validated across different populations and liver conditions, with research showing it to be particularly reliable at identifying people who are at low risk for advanced liver scarring.
However, studies have demonstrated important limitations. The accuracy rate of FIB-4 for diagnosing established fibrosis is approximately 80%, which means about 20% of results may be incorrect. Additionally, certain factors can influence the accuracy of the score, including medications, other health conditions, or temporary illnesses that can affect liver enzyme levels or platelet counts.
