Nutrition & Gut Health Checks

The following are nutrition and gut health checks available through iScreen. 

• Gut Health Check (91 tests included)
There are medical explanations and labels for many gut problems, but the big exception is Irritable Bowel Syndrome (IBS). Since many gut disorders have similar symptoms to IBS, ruling out a more serious underlying gut disease is an important first step.

• Microbiome Check (32 tests included)
As well as analysing your beneficial and pathogenic bacteria, our comprehensive microbiome test also includes testing for parasites and yeast overgrowth, and also provides an assessment of your digestive markers. This holistic picture provides actionable insights to help you improve your gut health.

• Complete Microbiome Mapping PCR - GI Map (91 tests included) 
The panel is a comprehensive collection of microbial targets as well as immune, inflammation and digestive markers. It screens for pathogenic bacteria, commensal bacteria, opportunistic pathogens, fungi, viruses, and parasites.

• Nutrition check (10 tests included) 
Many nutrients are absolutely essential for good health. It's possible to get most of them from a balanced, real food-based diet, however the typical modern diet lacks several very important nutrients. Find out your nutritional status with this simple nutrition blood test.

• Essential Fatty Acids Check (9 tests included)
Your body can't make omega 3 and omega 6 essential fatty acids and these must come from the food you eat. These essential fatty acids play a critical role in brain function, and immune and inflammation responses.

• Copper to Zinc ratio (3 tests included) 
Copper and zinc are essential nutrients in our body and they work together. There are many problems that can occur if we have a copper and zinc imbalance.

• B Vitamins Check (2 tests included) 
B vitamins are important for the nervous system and brain function as well as a healthy liver, hair, skin and eyes. They also strengthen the immune system.

• Vitamin D check (1 test included) 
Over 30% of adults are estimated to be vitamin D deficient which can cause muscle weakness and fatigue. This simple vitamin D test will tell you if you have a deficiency.

• Iron Check (4 tests included)
Iron deficiency is the most common nutritional problem in New Zealand. A shortage of iron leads to anaemia and feelings of weakness, tiredness and dizziness. 

• Parasite PCR check (18 tests included) 
Some gut problems can be a consequence of an undetected gut infection. A significant number of IBS (irritable bowel syndrome) cases could actually be due to undiagnosed gut pathogens such as Blastocystis hominis and Dientamoeba fragilis.

• Heliobacter Pylori Check (1 test included) 
Helicobacter pylori (H. pylori) is a bacteria that infects the stomach, and is now known to be a major cause of peptic ulcer disease. One third of New Zealanders are believed to carry the bug, but many don’t realise they have it.

• Coeliac Check (2 tests included) 
Coeliac disease is an autoimmune disorder triggered by gluten that can cause severe digestive problems. It affects 1 in 100 New Zealanders who are mostly diagnosed in adulthood.

• Coeliac HLA Genotyping (2 tests included) 
Patients with coeliac disease almost always have specific variants of HLA-DQ2 and HLA-DQ8. These variants are necessary, but not sufficient, for the disease to occur.

• Intestinal Permeability (Leaky Gut) Check (3 tests included) 
When the lining of the intestine and gut microbiome are compromised, unwanted substances can cross the barrier into the blood and activate an immune response in a condition known as 'leaky gut' or 'intestinal permeability'.

• Gut Inflammation Check (1 test included) 
There are medical explanations and labels for many gut problems, but the big exception is Irritable Bowel Syndrome (IBS). Since many gut disorders have similar symptoms to IBS, ruling out a more serious underlying gut disease such as inflammatory bowel disease is an important first step.

• SIBO Check (2 tests included) 
If the small intestine becomes overgrown with bacteria it can lead to malabsorption of key nutrients and symptoms of irritable bowel syndrome. Find out more with a simple breath test.

• Thyroid Cofactors Check (2 tests included)
Thyroid dysfunction especially hypothyroidism is common and a condition where supplements are widely recommended.

• Organic Acids Check (Metabolomic Mapping) 
The Organic Acids Metabolomic Profile is a nutritional test providing insights into organic acids and a view into the body's cellular metabolic processes.

• Pancreatic Check (1 test included) 
Pancreatic insufficiency is the inability to properly digest food due to a lack of digestive enzymes. This can cause health issues such as diarrhoea, gas, bloating and stomach pain.

• Pancreatic Insufficiency Check (1 test included) 
Pancreatic insufficiency is the inability to properly digest food due to a lack of digestive enzymes. This can cause health issues such as diarrhoea, gas, bloating and stomach pain.
