Anyone experienced with fibroscan results?? Stef2011?

[Bravesoul]

I recently got my fibroscan done for the first time. It turned out to be a very unusual experience. The doctor performing the scan couldn't get a reading using the M probe no matter how hard he tried, despite my being a slim (borderline underweight) individual. Eventually he gave up on the M probe and used the XL probe instead, which worked and gave a median value of 6.1 kpa value. Now I'm concerned if the XL probe might have underestimated my fibrosis because it is designed for obese individuals. Given my low BMI and >6kpa fibroscan score using the XL probe, could it indicate that I have significant fibrosis and in need of treatment? My viral load is 770 and alt is 19.
