GastroCheck tests for both Small Intestinal Bacterial Overgrowth and the Helicobacter Pylori infection.

The Small Intestinal Bacterial Overgrowth test is performed at one of our clinic locations. The Helicobacter Pylori Stool Antigen test is performed at your own convenience and the sample is posted directly back to the lab.

Helicobacter Pylori is thought to affect 50% of the world's population. Small Intestinal Bacterial Overgrowth is present in over 50% of patients clinically diagnosed with Irritable Bowel Syndrome (IBS).

Small Intestinal Bacterial Overgrowth Test



Small Intestinal Bacterial Overgrowth occurs when there is an excessive amount of bacteria inhabiting the small intestine. Symptoms are very similar to those of Irritable Bowel Syndrome (IBS).

SIBO may result in the inability of the intestine to function properly. This may significantly affect the absorption of nutrients and damage the lining of the small intestine which may lead to leaky gut. Leaky gut is associated with immune reactions, autoimmune diseases, and generalised inflammation.

There is a strong association between SIBO and

  • Irritable Bowel Syndrome
  • Fibromyalgia
  • Acne Rosacea
  • Coeliac Disease
  • Crohn's Disease
  • Diabetes

Studies have shown that in over 50% of IBS diagnosis, Small Intestinal Bacterial Overgrowth is present. This test can be performed in clinic or purchased from our online store.

The Hydrogen and Methane breath test is used to detect Small Intestinal Bacterial Overgrowth (SIBO). This is a non-invasive investigation. You will be asked to perform a baseline breath sample by blowing into the analyser. Following this, you will be given a testing solution to consume. You will then be called into the clinic room at regular intervals of 15/20 minutes to perform breath samples. If bacterial overgrowth is present in the small intestine, the bacteria will break up the solution. Hydrogen, Methane and carbon dioxide gases are produced from the bacteria metabolising the test solution. Hydrogen and Methane have a small molecular size which means that they pass easily through the wall of the small intestine and into the blood stream. When your blood circulates around your body to your lungs, these gases diffuse out of the bloodstream and are measured in your breath samples. This test can be performed at one of the clinics and results are available on the day of testing. SIBO testing kits can be purchased from the online product store if you are unable to attend one of the clinics.

Helicobacter Pylori Test



Helicobacter Pylori is a common infection that can cause inflammation of the stomach and is thought to be involved in the development of peptic ulcers. It is found in half of the world’s population.

Helicobacter Pylori testing can be performed to support a diagnosis of Helicobacter Pylori infection or to find out if your treatment for the Helicobacter Pylori infection was successful. A Helicobacter Pylori stool antigen test checks your stool (feces) for Helicobacter Pylori antigens. These are substances that trigger the immune system to fight the infection.

It is recommended that Helicobacter Pylori testing is performed by having biopsies taken during an endoscopy (camera test), having a stool antigen test performed, or a urea breath test(1).

Serology (blood) test is not recommended to diagnose eradication of the Helicobacter Pylori infection as antibiodies to the infection can remain in your system for a long time(2).

A stool antigen test can be performed in the comfort of your own home with no fasting requirement. Testing kits can be purchased directly through the online store 24/7. A Helicobacter Pylori stool antigen test is suitable for both adults and children.

Lactose Malabsorption Test



Lactose Malabsorption occurs when there is an inability to fully digest the ‘milk sugar’. Symptoms can begin soon after eating or drinking lactose containing food or drinks.
Lactose consists of two sugar units. An enzyme called lactase is required to split the lactose sugar into two single units for absorption. If you do not have enough lactase enzyme, lactose cannot be broken down and travels to the large intestine where it is digested by bacteria in your colon. The products produced by this process can cause symptoms such as diarrhoea, gas, bloating, nausea, vomiting, upset stomach, or flatulence.
The Hydrogen and Methane breath test is used to detect lactose malabsorption. This is a non-invasive investigation. You will be asked to perform a baseline breath sample by blowing into the analyser. Following this, you are given a lactose testing solution to drink.

You will then be called into the clinic room at regular intervals to perform breath samples. If lactose is not absorbed, it travels to the large intestine. In the large intestine, the bacteria will break up the lactose and gases such as hydrogen, methane and carbon dioxide are produced. Hydrogen and methane have a small molecular size which means that they pass easily through the wall of the intestine and into the blood stream. When your blood circulates around your body to your lungs, these gases diffuse out of the bloodstream and are measured in your breath samples. This test can be performed at one of the clinics and results are available on the day of testing. Lactose malabsorption kits can be purchased from the online product store if you are unable to attend one of the clinics.

Fructose-Sorbitol Malabsorption Test



Fructose and Sorbitol are quite often found together in fruit or added to processed foods. Some people have trouble absorbing these sugars properly when they are consumed at the same time. This can lead to symptoms such as bloating, cramps, diarrhoea/constipation, gas, nausea, or wind.

Testing is non-invasive. Hydrogen and methane gas measurements are analysed from breath samples taken at regular intervals following the ingestion of a testing solution. This test is only available in the clinic.

Fructose Malabsorption Test



Fructose can be present naturally in foods such as fruit and some vegetables, or found in many processed foods and drinks. Foods that contain fructose include oranges, apples, mangos, pears, prunes, melons, raisins, honey and fruit juices. Fructose malabsorption occurs when the small intestine fails to fully absorb this sugar. As a result, fructose is transported to the colon where it is broken down by bacteria in the colon. Hydrogen, methane and carbon dioxide gases are produced as a result of this malabsorption.

Some people can tolerate more fructose than others, so symptom severity can differ depending on the amount of fructose consumed. Symptoms include bloating, diarrhoea, constipation, nausea, or abdominal cramps. People with Coeliac disease and IBS are at a higher risk of suffering from fructose intolerance. The Hydrogen and Methane breath test measures the gases produced by the bacteria in the colon to determine if the fructose sugar has not been absorbed properly in the intestine. This test is only performed in the clinic.

Sorbitol Malabsorption Test



Sorbitol is often used as a sweetener in "diet" or "sugar free" foods and drinks. It can also occur naturally in foods such as pears, prunes, peaches, cherries, and plums. In large quantities, Sorbitol may cause osmotic diarrhoea, however in patients that suffer from IBS, lower amounts of Sorbitol can cause abdominal and GI symptoms.

The Hydrogen and Methane breath test is performed to test for sorbitol intolerance. This is a non-invasive test that is performed in the clinic.

Sucrose Malabsorption Test



Sucrose is normally broken down in the small intestine by the sucrase enzyme. When Sucrose Malabsorption occurs, the sucrose is not properly broken down or absorbed in the small intestine. It travels to the colon where it is metabolised by colonic bacteria.

Sucrose is also known as table or cane sugar. The Hydrogen and Methane breath test is performed to test for sucrose malabsorption. This is a non-invasive test that is performed in the clinic.

Coeliac Test



Coeliac Disease is an autoimmune disorder caused by a permanent intolerance to gluten - a protein found in grains such as wheat, barley and rye.

When people with Coeliac Disease eat foods or use products that contain gluten, this damages the intestinal villi. Without healthy villi, a person can become malnourshed.

Candida Albicans Test



Candida is a yeast-like fungus that is normally present on the skin and in mucous membranes such as the vagina, mouth, or rectum. It is also a normal inhabitant of the human gut.

However, when a person becomes dysbiotic, Candida can morph to become a pathogenic (injurious) invasive fungus and give rise to Candidiasis which is caused by over growth of Candida, predominantly Candida albicans.

Vitamin D Test



Vitamin D deficiency can be a serious problem and does not have very obvious symptoms. It increases susceptibility to other more serious conditions.

Vitamin D maintains the levels of calcium and phosphate which in turn is needed for normal bone mineralisation, muscle contraction, nerve conduction and general cellular function.
