Fructose malabsorption test preparation instructions

  • The physician should be notified of any recent antibiotic treatment and/or runny diarrhea prior to test. (These conditions can impact the validity of the test.)
  • The patient should not eat high-fiber or slowly digesting foods the day before the test.
    • Such foods include bran, course breads, nuts, beans and similar vegetables.
    • This will reduce the cance of hydrogen and methane being produced from other food sources during the period of the test.
  • The patient should fast overnight (at least 12 hours) before the test, consuming no food and having only water to drink.
  • The patient should not smoke for at least one hour before collecting any air-sample used for the test.
