There is a fructose malabsorption breath test however, it is not available were I live. In addition it only tells you if you cannot handle a 25 gram load of fructose but it does not tell how much less than 25 grams you can handle. Normally most people can handle more than 50 grams.
I used a dietary exclusion method. I removed all foods that contained more fructose than glucose from my diet. I used table in Figure 2 of this article as a guideline for which foods to remove from my diet. Using this method it was quite easy to figure out which foods I could not handle.
