No, I have to drink some fructose-infused liquid and then I blow in a breathalyzer every 30 min for 3 hours total. (I have to stay in the waiting area for three hours and they call me back for the testing.) This is how they measure the amount of fructose that is not absorbed.
Dx UC 1979 at age 14 - (I know, some kind of record)

GI Doc recently told me I have "lead pipe syndrome" which is advanced scarring of colon
