There’s a lot of confusion around surrounding food sensitivity and allergy testing. In particular, the testing methods seem to cause a lot of questions. We’re asked all the by customers, which test they should get, so today we’re clearing things up and explaining the differences between our bioresonance hair testing and our blood testing.


Bioresonance Hair testing Explained

Bioresonance hair testing is a holistic form of therapy. It is categorised as a complementary and alternative medicine (CAM) – a diverse group of therapies, practices and products which fall outside of conventional medicine or healthcare. Bioresonance testing analyses the bioresonance of a small hair sample to determine potential food sensitivities, vitamin deficiencies, gut biome and metal toxicities. Bioresonance testing does not test for allergies. Also, these tests do not constitute a medical diagnosis, but they can help people to identify food intolerances and alter their diet accordingly.


Blood testing Explained

Blood testing is the only form of allergy testing we offer. However, similar to the fingers and thumbs scenario, all of our allergy tests are blood tests, but not all of our blood tests are allergy tests.

We also offer food intolerance testing using your blood sample, either as part of a test that also checks for allergies or as a stand-alone intolerance only test. Our blood tests analyse the blood for certain immunoglobins in response to various allergens and food items.

What is Immunoglobin?

Immunoglobin, also known as ‘antibodies’ are large y-shaped proteins used by the immune system to neutralise threats. Think of them as your tiny personal bodyguards. They fend off pathogens like viruses and harmful bacteria and even fungi.

There are 5 types of human immunoglobins [1];

  • IgM
  • IgG
  • IgA
  • IgE
  • IgD


IgE Allergy Testing

Immunoglobin E (IgE) protects the body against parasites and is also what causes allergic reactions in those with allergies. This is because, occasionally, even our immune system gets things wrong, and it sees an allergen as an ‘invader’ out to harm you. So, your body sends out a batch of IgE’s to deal with the ‘threat’.

IgE blood testing is one of the medically validated diagnostic methods of diagnosing an allergy [2]. With our allergy blood testing, we analyse the sample you send in against various allergens and check for IgE in response to those allergens, to determine if an allergy is present.


IgG Food Intolerance Testing

Blood tests such as our Prime 110 and Choice 70 test for both allergies and intolerances. Because these two are different responses from the body, different immunoglobin types are used in response to them. In these tests, we analyse the blood sample against various food items for both an IgG and IgE response, to determine if food intolerances or allergies are present, respectively.

A food intolerance can be identified by the IgG antibodies produced in response to a particular food item. This happens in a similar manner to the allergic reaction, but more slowly and to a less drastic degree – as the symptoms are much less severe. Studies indicate that IgG testing can be an effective diagnostic method for food intolerances [3].


Which Test to Get

So which test should you get? Well, it depends on what you’re looking for. If you are specifically looking to learn about any allergies that you may have, then blood allergy testing is your only option, since allergies can’t be tested for using a hair sample.

If you are looking for a holistic approach to optimising your health, then bioresonance hair testing may be exactly what you need as these tests can analyse a variety of different health markers such as food sensitivity, gut biome, nutritional deficiencies and metal toxicity.

Because each person is different, we can’t say that any one of our tests is suitable for all needs, but we will say that both our Choice 70 and Prime 110 tests analyse the blood sample for both food intolerances and allergies via IgG and IgE respectively.
