Simple blood test may spot hidden liver damage in obesity
NCT ID NCT07663188
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a common blood test called FIB-4 can accurately predict liver fibrosis (scarring) in people with obesity. Researchers will compare FIB-4 results with liver stiffness measurements from a specialized scan (FibroScan) in 400 obese patients. If the blood test works well, it could help identify those who need further liver evaluation without unnecessary procedures.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If FIB-4 proves accurate, it could become a standard first-step test to identify liver fibrosis in obese patients without needing immediate specialized scans.
- What could go wrong
- This is an observational study, not a treatment trial. The FIB-4 test may not be accurate enough to replace current methods, and results may not apply to all patient groups.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Consecutive adult obese patients (BMI ≥ 30 and ≤ 40 kg/m²), aged 18-64 years, attending the outpatient Clinical Nutrition Center for the Research and Care of Obesity and Metabolic Diseases at IRCCS "Saverio de Bellis" (Castellana Grotte, Italy). Patients are enrolled during a Day Service access in which routine blood tests and liver stiffness measurement by FibroScan are performed as part of standard clinical practice. Patients are stratified into two cohorts based on FIB-4 score: Cohort 1 (FIB-4 ≥ 1.3) and Cohort 2 (FIB-4 \< 1.3). Patients with known liver diseases other than MASLD, pregnancy, or current treatment with GLP-1 receptor agonists known to affect hepatic steatosis (Semaglutide or Tirzepatide) are excluded
