Breath Tests (Tests Done at Good Hope Hospital)

The Laboratory routinely offers the following 'Breath Tests' :
1. 13Carbon-Urea Test - Helicobacter pylori Investigation.
2. Hydrogen Breath Test. Two Types of Hydrogen breath tests available are:

  • Lactose Tolerance Test
  • Glucose Hydrogen Breath Test

13Carbon-Urea Test - see Helicobacter pylori investigation

This test is for patients being investigated to either diagnose or confirm eradication of the H.pylori infection. The 13Carbon Urea test is safe as it uses a non-radioactive label, is well tolerated by patients, and the procedure can be completed within 30 minutes. Each patient is provided with a "Patient Information Leaflet" giving straight-forward information about the test, at the same time as the appointment letter is sent out. A copy of this leaflet is available, on request.

Lactose Tolerance Test

Patients can present with a variety of GI symptoms due to absolute or relative lactase deficiency. Lactose is a ubiquitous part of the diet and therefore patients can still have symptoms even if they have eliminated milk from their diet. The test is safe, and takes approximately 2.5 hours to perform. The test is based on the principle that if the patient has appropriate amounts of lactase in the GI Tract then Lactose will be split into Glucose and Galactose and absorbed into the blood stream. However, if insufficient Lactase is present, bacterial action will metabolise the Lactose anaerobically to produce hydrogen. The hydrogen is taken in the blood stream to the lungs and expired. The levels of hydrogen measured are of the order of 1 to 50 parts per million. A simple sampling device is used to collect the breath hydrogen samples. This test is very well tolerated by patients.

Glucose Hydrogen Breath Test

Patient suspected of having bacterial overgrowth in the small intestine are tested by the measurement of breath hydrogen. Glucose is used as a fermentable substrate by pathologically high levels of small bowel bacteria. The hydrogen  released by the fermentation is rapidly absorbed and expired in the breath. An increase in breath hydrogen >12 parts per million above the fasting level is indicative of bacterial overgrowth. This takes approximately 3 hours to perform.

Metabolic Clinics (Tests Performed at Good Hope Hospital)

The following protocols for common function tests are available :

  • Arginine & Clonidine Provocation Test for Growth Hormone Deficiency
  • Creatinine Clearance
  • Urea Breath test for investigation of Helicobacter pylori infection
  • CRH Test
  • Dexamethasone Suppression Test (low dose, High dose and overnight)
  • Glucose Tolerance Test (for suspected diabetes or acromegaly)
  • GnRH Test
  • Mixed meal tolerance test
  • Synacthen Stimulation Test (short).
  • Water deprivation test

All Function Tests are carried out in the Function Test Room in the Treatment Center (room B22), Good Hope Hospital on a Friday morning clinic. Patients are sent a location map when arrangements are made for Function Tests. If a Protocol is required, or any information or advice about the tests, please contact Dr David Kennedy or Jessie Raju on ext 47254.
