Percentage of range - how do you work it out

[Book99]

Hi - last week I posted some results. Slow Dragon and others kindly commented.

T3 3.2 pmol/L -

FT3 levels normal (normal range 3.1 - 6.8 pmol/L)

Slow Dragon said this was 2.5% through range. How do you work out the percentage please?

Thanks

I do it like this: range from 3.1-6.8 = 3.7. And you are 0.1 of that range. So your percentage is 1 divided by 3.7 = 2.7%. You can see yourself you're only barely into the range.
