FibroScan Results Interpretation: Severe Cirrhosis with Minimal Steatosis

Your FibroScan shows severe cirrhosis (liver stiffness 53.7 kPa) with reliable measurement quality (IQR 10%) and minimal to no liver fat (CAP 215 dB/m).

Liver Stiffness (53.7 kPa): Advanced Cirrhosis

Your liver stiffness of 53.7 kPa is extremely elevated and indicates established cirrhosis (F4 fibrosis). To put this in context:

  • Normal liver stiffness: <7 kPa
  • Significant fibrosis (F≥2): typically >8.2 kPa 1
  • Advanced fibrosis (F≥3): typically >9.7 kPa 1
  • Cirrhosis (F4): typically >13.6 kPa 1
  • Your value of 53.7 kPa: Far exceeds cirrhosis threshold

The measurement reliability is excellent with an IQR of 10% (well below the 30% threshold for unreliable measurements), meaning this result is technically valid 2.

CAP Score (215 dB/m): Minimal Steatosis

Your CAP of 215 dB/m indicates minimal or no significant liver fat:

  • No steatosis (S0, <5% fat): CAP <248 dB/m 2
  • Mild steatosis (S1): CAP >302-310 dB/m 1, 3
  • Moderate steatosis (S2): CAP >331 dB/m 1
  • Severe steatosis (S3): CAP >337 dB/m 1
  • Your value of 215 dB/m: Below all steatosis thresholds

This is actually favorable—it means fatty liver disease is not contributing to your liver damage, and steatosis is not artificially elevating your liver stiffness measurement 4, 5.

Critical Next Steps

You require immediate hepatology referral and comprehensive cirrhosis management 2. This level of liver stiffness demands:

  1. Identify the underlying cause if not already known (viral hepatitis B/C, alcohol, autoimmune disease, metabolic conditions)

  2. Screen for cirrhosis complications:

    • Esophageal varices (endoscopy needed)
    • Hepatocellular carcinoma (ultrasound + AFP every 6 months)
    • Portal hypertension assessment
    • Liver synthetic function (albumin, INR, bilirubin)

  3. Assess for decompensation signs: ascites, hepatic encephalopathy, variceal bleeding

  4. Consider liver transplant evaluation depending on clinical status and liver function scores (MELD, Child-Pugh)

Important Caveats

While your measurement is reliable (IQR 10%), liver stiffness can be temporarily elevated by:

  • Active liver inflammation (elevated ALT/AST)
  • Acute hepatitis
  • Biliary obstruction
  • Congestive heart failure

However, a value this high (53.7 kPa) almost certainly represents true advanced cirrhosis rather than a transient elevation 6.

This is not a result that can be managed in primary care—you need specialist hepatology evaluation urgently to assess disease severity, complications, and treatment options.
