Frequently Asked Questions
Allergies effect 1 in 3 people at some time in their lives. Food sensitivities are more common, can occur at any age, triggering many different symptoms and
contributing to a variety of disorders including:
- Inflammatory bowel disease
- Mood swings
- Skin problems
- Rheumatoid arthritis
- Recurrent ear infections
A test helps decipher which foods and triggers to avoid to drastically reduce the symptoms you may experiencing. Allergens (IgE positive results) should be avoided completely and only re-introduced under medical supervision. Included with intolerance test results is a Food Reaction Patient Guide which will provide
information on how to interpret your results, build your own customized, 4-day rotation diet, dietary recommendations, and alternative food options.
Results also help your practitioner identify other possible causes of adverse food reactions and develop a management strategy.
Blood tests for IgE (formerly called RAST) can be used to diagnose allergens (both food and inhalants) that may be causing allergies with an immediate onset. Many studies have observed that the results from IgE testing correspond well with skin prick testing or oral challenge. It has also been mentioned in the medical literature that IgE testing would assist general practitioners in identifying patients to be kept in primary care from those who should be referred to an allergy specialist.
IgE testing has been shown to be very useful for detecting food allergies in various conditions. In a study on children with dermatitis and asthma, food allergies were investigated by the double-blind placebo-controlled food challenge (DBPCFC), skin prick testing and IgE blood test. The IgE levels were able to predict 95% of positive and 90% of negative food challenge reactions, providing comparable results to skin prick testing. The authors suggested that use of the IgE test could eliminate the need to perform the more time consuming DBPCFC in patients suspected of having IgE-mediated allergies. It may also be a safer option for those at risk of an anaphylactic event.
No, there are many different testing methods. We utilize a very accurate test that looks at the immune system’s response to at least 96 different foods. The results indicate a mild, moderate or severe reaction to each food. The tests we perform look at not only true food allergy but the common food intolerances or sensitivities that effect up to 50% of the population.
The laboratory we use for IgE and IgG testing, US BioTek Laboratories is a Worldwide Leader in Specialty Medical Testing
With over 30 years’ experience in enzyme-linked immunosorbent assay technology (ELISA), they have performed millions of samples.
Duplicate runs of each test are performed for added accuracy.
A simple finger prick blood test is all that is needed for IgG testing. This can be done at home and posted in the return envelope provided.
IgE, ALCAT or combined tests require a blood draw to be taken by your local pathology centre. The kit with all instructions is posted to you.
Results take between 1 and 3 weeks depending on the test. An electronic and colour hardcopy report are then forwarded to you and your clinician if requested.
You may also use our in clinic service either before testing to ascertain with test is best suited for you or afterwards to explain results, management strategies and diet guidelines if needed. Natural treatment options, management of leaky gut or immune and digestive system health is also available.
After hours and weekend appointments are available. A referral letter is not required. Testing and practitioner support is available throughout Australia.
No, a referral is not necessary, you can order a test or book a consultation without referral. If however you have a health care practitioner and would like results to be forwarded to them you can request this at the time of testing.
Yes, a change in diet can produce immediate results. As trained naturopaths, nutritionists and dieticians, we can also offer dietary advice around food intolerance or restrictive diets, herbal and nutritional support for digestive and immune health which may be contributing and desensitization for specific intolerances or allergies if any of these are required.
