I think it’s time for another addition to my ‘Close Up’ series. Today, I want to write a little bit about the lactose/fructose tolerance hydrogen breath test.
It’s important to eat the last meal not a minute later than 10pm if your test is scheduled at 8am. The last liquid should be consumed at least 6 hours before the test starts.
It’s not necessary to stop eating the substance you might have an intolerance to until you have the results. So continue eating your normal diet unless your symptoms are unpleasant.
If you are taking medication, check with your doctor about the possibility of a false negative result. Also, do not smoke or brush your teeth in the morning!
