Do not take non-essential medications or supplements until the test is completed, unless your physician has advised you otherwise. Do not chew gum, eat candy, or use mouthwash until the test is completed.

No smoking, including second-hand smoke, for at least 1 hour before or at any time during the breath test. No sleeping or vigorous exercise for at least 1 hour before or at any time during the breath test. Do Not Use Toothpaste.

Additional Information:
This test uses lactulose; since lactulose contains galactose and lactose, it is not recommended for individuals who have had allergic reactions to lactulose, or who are on a galactose/lactoserestricted diet. It should be used with caution in diabetics.

Do not open, remove, or loosen tops of collection tubes–this will break the vacuum and make it impossible to perform your test. Do not stick your finger into the mouthpiece/plastic bag – there is a sharp needle inside.

We do not suggest collecting during an acute infectious illness.

This collection is extremely time-sensitive. You need to carefully plan the morning around these timed collections. An uninterrupted 2 or 3 hours is ideal.

Use the Breath Collection Schedule Table on the front of the Requisition to help you schedule your collection times.

This test is not suitable for children under 25 pounds.

Description: Bacterial overgrowth of the small intestine is a serious digestive disorder that is treatable after proper diagnosis. Although widespread, it is frequently unsuspected in cases of chronic bowel problems and carbohydrate intolerance because its symptoms often mimic other disorders.
