FibroScan (Transient Elastography)
A FibroScan (also called transient elastography) is a non-invasive test used to assess the health of your liver—especially liver stiffness (fibrosis) and fat accumulation (steatosis).
What FibroScan Measures
1. Liver Stiffness (Fibrosis Score)
- Measured in kPa (kilopascals)
- Indicates how much scarring (fibrosis) is present
Typical interpretation may vary slightly depending on the liver condition.
2. CAP Score (Controlled Attenuation Parameter)
- Measured in dB/m (decibels per meter)
- Shows fat content in the liver
Why FibroScan is Done
- Detect fatty liver (NAFLD/NASH)
- Evaluate liver fibrosis or cirrhosis
- Monitor chronic liver diseases (Hepatitis B, C, alcohol-related disease)
- Avoid or reduce the need for liver biopsy
Procedure
- You lie on your back with your right arm raised
- A probe is placed on your skin (similar to ultrasound)
- It sends painless vibrations into the liver
- The test takes about 5–10 minutes
- No needles and no sedation are required
Things That Affect Results
- Recent meals (fasting for 2–3 hours is recommended)
- Obesity
- Inflammation (hepatitis flare)
- Alcohol intake
- Congestion (heart failure)
Advantages of FibroScan
- Non-invasive, quick, and painless
- Provides immediate results
- Can be repeated regularly for monitoring
Limitations
- Less accurate in very obese patients or in patients with ascites
- Cannot completely replace liver biopsy in all cases
