(SADDC): PROCEDURES

Hydrogen Breath Testing

This is a test for “lactose intolerance” that measures breath samples for hydrogen levels. The body makes too much hydrogen when lactose is not broken down properly in the small intestine.

PREPERATION

The patient drinks a lactose-loaded beverage and then the breath is analyzed at regular intervals to measure the amount of hydrogen. Normally, very little hydrogen is detectable in the breath, but undigested lactose produces high level of hydrogen. Smoking, some foods and medications may affect the accuracy of the results. Please check with the doctor about foods and medications that may interfere with test results.

LACTOSE INTOLERANCE

This test measures breath samples for hydrogen levels. The body makes too much hydrogen when lactose is not broken down properly in the small intestine.

Preparation

The patient drinks a lactose-loaded beverage and then the breath is analyzed at regular intervals to measure the amount of hydrogen. Normally, very little hydrogen is detectable in the breath, but undigested lactose produces high level of hydrogen. Smoking, some foods and medications may affect the accuracy of the results. Please check with the doctor about foods and medications that may interfere with test results.

FRUCTOSE MALABSORPTION TEST

This test is for “fructose Intolerance” that measures breath samples for sugar levels. The body makes too much sugar when fructose is not broken down properly in the small intestine. Please inform the doctor of any antibiotic therapy and/or recent or current diarrhea. These can affect the test.

Preparation

The patient should not have eaten slowly digesting foods such as bean, bran or high fiber cereals at least two days prior to the exam. Do not smoke, sleep or exercise vigorously for a least ½ hour before or during test. The patient will fast for 12 hours with no food and only water to drink before the test. Drink a 12oz Coke or Pepsi three hours before your office visit. A breath sample is taken 3 hours after ingestion of the soda. The results will indicate if the patient is a fructose malabsorber.

BACTERIAL OVERGROWTH TEST

This test is run to check for abnormal bacterial overgrowth in the small bowel. This can lead to bloating, pain, diarrhea or weight loss.

Preparation

The patient should not have eaten slowly digesting foods such as bean, bran or high fiber cereals at least two days prior to the exam. Do not smoke, sleep or exercise vigorously for a least ½ hour before or during test. The patient will fast for 12 hours with no food and only water to drink before the test. One hour before the office visit drink the lactulose prep as instructed by the Medical Assistant. A breath sample will be taken every 15 minutes and analyzed. This test could take up to 4 hours to complete.
