Food Intolerance Test is recommended for age two (2) years old and above. |
| Frequently Asked Questions (FAQs) | : |
This test is based on the immune system’s ability to produce antibodies in response to certain food. If a food has been avoided for more than 3 months, it is likely that IgG antibody levels will be insufficient to be detected by the test and may give a normal result. To test intolerance to a certain food, it should be included in the daily diet, or at least every other day, for 4-6 weeks before testing. However, if the food concerned is known to cause extreme symptoms/discomfort, do not reintroduce it.
Once you have received your test results, it is advisable to consult a nutritionist who can help advise on dietary changes and provide a supplement program. They may also offer support and encouragement with regular progress checks, as it can be quite a daunting task to persevere with a new diet on your own.
No. Lactose intolerance is the inability to digest lactose, the major sugar found in milk, and is caused by a deficiency of the enzyme lactase. The Food Intolerance Test detects IgG-mediated food intolerance caused by specific proteins found in milk, but does not detect the lactase enzyme and, therefore cannot diagnose lactose intolerance.
Yes, but we recommend a minimum age limit of 2 years.
Most people do not need to have a re-test, but if you would like to take another test, we advise a period of 6 months between tests. If symptoms have improved and you have successfully re-introduced “problem” food, a re-test is necessary.
It is occasionally observed that patients react to food that they are convinced they have never eaten. Although not unusual, it is attributable to a false positive result, but instead a “cross-reaction” with another food. Some food contain identical antigens (food proteins), even though they are not related to each other and/or do not belong to the same food group. These identical proteins will be detected by the same antibody, thus producing an elevated result.
If, after changing your diet according to test results, improvements have not been achieved after 3 months, food intolerance is unlikely to be the cause of your symptoms and other investigations should be undertaken. Results of the Food Intolerance Test are intended as a guide to diet alteration only and should be complementary to advice from a healthcare professional. |

| Frequently Asked Questions (FAQs) | : | Q: What is FoundationOne CDx? A: FoundationOne CDx is a tissue based comprehensive genomic profiling service for all solid-tumors to help support efficient-personalized treatment decisions. FoundationOne CDx is a next generation sequencing based in vitro diagnostic device for detection of substitutions, insertion and deletion alterations and copy number alterations in 324 genes and select gene rearrangements as well as genomic signatures including tumor mutational burden (TMB) and microsatellite instability (MSI) using DNA isolated from formalin-fixed embedded (FFPE) tumor tissue specimens. Q: Do all results lead to actionable treatment options?A: Each individual cancer is unique and test results vary depending on the tumor type. When applicable, test results may help identify : 1. A therapy approved to treat your specific tumor type and shown to be effective in targeting one or more of the alterations found by the test. 2. A therapy approved in another tumor type but possibly effective in targeting one or more of the genomic alterations found by the test 3. A clinical trial evaluating therapies under development which may work by targeting an alteration found by the test. Q: Do the test apply to all types of cancer?A: Our suite of comprehensive genomic profiling (cGP) assays can help deliver meaningful molecular insights across the broad spectrum of tumor types including but not limited to :

Test results provide information about clinically relevant alterations, potential targeted therapies, available clinical trials, and quantitative biomarkers that may support immunotherapy clinical trial enrollment. Q: How does genomic testing differ from genetic testing? A: Genomic testing looks at mutations in the tumor itself. Genetic testing looks at inherited mutations that are in all cells. Foundation Medicine testing is genomic testing, which looks at the mutations in the tumor. The mutations in the tumor are what may impact tumor growth, spread and response to therapy. |
