I had a fibroscan this week. Overall, good news. No fibrosis, ir scarring. However, I was a little perturbed that my CAP score, which measures the amount of fat in the liver, was 268. The ranges for CAP scores are as follows: 230-260 means a low of 11% fat to 34% fat, considered S1 (mild steatosis); 260-290 translatetranslates to a range of 34% fat to 66% fat, S1(moderate steatosis); and 290 or higher, which translates into a range of 67% fat to 100%, S3 (severe steatosis). All that said, you can estimate your percentage of fat in your luver in relation to the lowest and highest numbers in your range. So, I estimated that, if a CAP of 260 equalsc34% fat and a CAP of 290 equals 66%, my fat percentage based on my CAP score if 268 would be roughly 42-45% fat buildup in my liver. Sound about right to you guys? Another group member said that my CAP of 268 would equal between 67-73% fat buildup., which is mathematically impossible if a much higher CAP of 290 only tanslates into 66% liver fat.
We must have some math wizards out there who can settle our little dispute. Whose calculations are correct? Mine (CAP of 268 = 42-45% fat)? Or the other member'member's (CAP of 268 = 67-73% fat)?

After my first fibroscan, my scores were high and leading to cirrhosis. After I had a liver biopsy, I only had mild hepatic steatosis. So, in my opinion, the ranges determine whether or not you need a liver biopsy to verify results. I’m obese, so it goes without saying that my fat is everywhere in my body. 😅
My scores weren't high, though. No scarring/fibrosis, abd CAP was 268. Tge upper limit for.for mild fatty liver is 260, meaning mine is just slightly above that. My question was, if a CAP of 260 equals 33% fat, thethen is it nnoi t logical that a CAP of 268 would represent roughly 42-45% fat? Remember that CAP of 290 equals 6% fat. The other group member I referred to says my CAP of 268 is equal to 67% to 73% fat, which I told him is IMPOSSIBLE if 260 CAP equals 33% and 290 290CAP equals 66%. Do You understand now?
I understood…making molehills out of math. Lol. Your logic is sound. Fibroscans are not 100% accurate and you’re stressing about math when you should be ecstatic about the results. Not saying you aren’t right. Just saying someone’s opinion about what they say shouldn’t matter.
Ok, I understand. It just bugged me that the guy said a CAP of 268 equally 67-73%, because that is so wrong! If a CAP of 290 equals 66% fat, there's no way a CAP of 268 could possibly be more than 41-42%. He wouldn't see the logic and simple math and ut frustrated me.
I've received one response in 18 hours and, unfortunately, he didn't seem to understand my question. Perhaps I phrased ut awkwardly, so I'll restate it as succinctly as possible.
Regarding the CAP score, which measures the amount of fat in a liver, if a CAP score of 260 dB (lowest end of S2, moderate grade) is roughly equal to 33% of the liver cells have fat, and a CAP score of 290 db is roughly equal to a 66% liver fat content, would it not logically follow that a CAP score of 268 db would be roughly equal to 42.5% fat content? It's simple enough to figure out, since there is a 30 db difference between the low end of S2 of 260 and a high end of 290, and a 33% difference between 33% fat (260 db) and 66% fat (290 db], each db point between the two extremes is equal to 1.08%. Therefore, subtract 260db from 268 db = 8 db × 1.08% = 8.64%. Now, we add 8.64% to the baseline of 33% (260 db) for a fat percentage for a CAP of 268 db of 41.64%. Sound correct?
I have that exact same CAP score, along with a 7.5 kPa. I estimated the same range as you did (low to mid-40 percent range) but wasn't sure if the scale worked that way. I would definitely think that lower in the range means less fat.

Update: Lowered FibroScan Scores
I’m so discouraged 
Fearful of my 8.3 fibroscan score due to so many family members dying of cirrhosis
