Blood Test Innovations Enable Early Prediction of Fatty Liver Disease

Recent advances in blood testing have made it possible to predict the risk of developing fatty liver disease decades before symptoms appear. Researchers have identified a set of five specific proteins in the blood that serve as early biomarkers for metabolic dysfunction-associated steatotic liver disease (MASLD), commonly known as fatty liver disease.

A study presented at the upcoming Digestive Diseases Week in San Diego highlights that this blood test can predict the onset of fatty liver disease with remarkable accuracy—84% at five years prior and 76% up to 16 years before clinical diagnosis. This is significant because early detection can lead to interventions that may prevent disease progression.

Dr. Shiyi Yu, lead researcher and gastroenterology resident at Guangdong Provincial People's Hospital in China, emphasized the importance of early risk identification. "Too often, individuals remain unaware of their risk until symptoms manifest, which can be too late for effective management," Yu explained. "Our findings suggest that plasma proteins, combined with factors like body mass index and daily exercise habits, can form a robust predictive model."

Fatty liver disease occurs when excess fat accumulates in the liver, which can lead to inflammation and scarring. If left unchecked, it doubles the risk of premature death compared to individuals without the condition. In this study, over 50,000 blood samples from the UK Biobank were analyzed for more than 2,700 proteins. The researchers identified five that serve as early warning signals.

Further enhancing the test's accuracy, incorporating traditional risk factors like BMI and physical activity increased predictive reliability to over 90% at five years and 82% at 16 years. The consistency of these results was confirmed through testing in a separate Chinese cohort, suggesting the model’s effectiveness across diverse populations.

Lead researcher Dr. Yu plans to present these promising findings on May 4. While preliminary, this research marks a significant step toward routine early detection, enabling doctors to intervene before irreversible liver damage occurs.
