A South African consumers' guide to scams, pseudoscience and voodoo science, OR, a critical thinker's guide to the ins and outs of Complementary and Alternative Medicine
Three complainants challenged whether the claim “YorkTest define Food Intolerance as a food-specific IgG reaction”, and the overall impression of both ads that the test would inform consumers if they had a food intolerance, was misleading and could be substantiated. Another complainant challenged whether the efficacy claims about migraines in both ads and depression in ad (b) were misleading and could be substantiated.
The UK ASA concluded the evidence was insufficient to support the claims.
Similar companies in South Africa make the same unfair claims, .e.g., ImuPro.
The IgG test, for ‘food intolerance, is being sold in South Africa by among other, ImuPro and Yorktest. As mentioned in other posts on CamCheck, the Allergy Society of South Africa, the American Academy of Allergy and the European counterparts, all state that there is no validity to this test. Yet they continue to be sold to the unsuspecting public.
This article describes this problematic test being marketed in Canada.
‘There is no validity’: Unproven blood tests for food sensitivity widely offered in Canada
More than 2 dozen health groups have warned about misuse, misinterpretation of IgG tests for food intolerance
ImuPro, a blood test offered by WellPro, a division of Molecular Diagnostic Services (Pty) Ltd, is bringing Dr Camille Lieners to South Africa in order to promote this blood test for assessing “hypersensitiivies”. It should be noted that Dr Lieners is neither a medical doctor nor a dietitian. She has a PhD from Luxembourg. She is, in other words, not a clinician, and does not directly care for healthy people or patients. But she is dispensing clinical ‘advice’. It is unclear what her ‘PhD’ was about, and it is unclear why she should be regarded as an expert in the clinical setting.
The owner of Molecular Diagnostic Services, Dr Dennis York, continues to promote this product for assessing “hypersensitivies” in spite of ASA rulings against the claims, and in spite of international consensus and position statements from allergy societies and representative organisations throughout the world including … Read the rest
This ASA ruling against the complainant, is interesting for it relates to changing of website contents, integrity, proof and mainly, being careful to copy the contents of a website before laying a complaint!
In essence: I noticed that the ImuPro website was still making claims contrary to the ASA’s previous rulings. I laid a complaint. The ASA sent the complaint to Dr York, who claimed that the links I spoke about were no longer present and probably in the cache of my browser (unlikely for I viewed this page after having cleared my cache – done regularly). The ASA checked his claims that the links were not active and confirmed this to be true. Of course, I stand by my claim.
Considering that the ASA were not able to access the website page, the complaint was dismissed. I re-iterate, I feel so strongly about individuals being … Read the rest
In Food Detective / H A Steinman / 15038 (26 March 2010), the Directorate ruled that claims on the respondent’s pamphlet distributed to healthcare professionals for its Food Detective kit were unsubstantiated. The respondent was instructed to withdraw the relevant claims and not use them again in future. In a subsequent ruling, dated 12 November 2010, a breach allegation lodged by the complainant was dismissed on the basis that the amended claims at issue were sufficiently different to those originally considered and ruled on to negate an argument of breach. In a letter dated 2 November 2011, the complainant lodged a new breach allegation against the respondent’s advertisement for Food Detective, as was seen in the programme of a recent Allergy Society of South Africa’s congress. The complainant submitted that the respondent continues to claim that the Food Detective is “an easy to use, rapid test … Read the rest
The South African ASA has previously ruled against the claims being made for IgG/ImuPro testing. Here is the UK ASA ruling against the same/similar product being marketed in the UK.
Molecular Diagnostic Services (Pty) Ltd is a company established by Dr Denis York. They market the ImuPro test, a blood test using IgG testing to predict foods that may be responsible for a number and range of illnesses. They state, among other: “the internationally respected ImuPro Food IgG Intolerance Test can pinpoint food intolerances”.
In fact, ALL allergy societies throughout the world, including the European Academy of Allergy and Clinical Immunology (EACCI), the American Academy of Allergy Asthma and Immunology (AAAAI), the Allergy Society of South Africa and Australian counterparts, have all issued clear statements stating that there is NO evidence in support of the claims for this test.
In fact, there is evidence showing that the test is BOGUS in predicting adverse reactions to food, and in some instances, may be downright dangerous. Does Dr York care? Considering the repeated ASA rulings against his company for the claims … Read the rest
In Imupro / H A Steinman / 14955 (11 February 2010), the Directorate accepted the respondent’s voluntary undertaking that an advertisement that contained the claim that the “the internationally respected ImuPro Food IgG Intolerance Test can pinpoint food intolerances” was a once off advertisement and will not be used again. The undertaking was accepted on condition that the claim was not used again in future.
A number of allergies and intolerances are very difficult to diagnose, even by experts, which has resulted in a great number of scam or unsubstantiated tests being advertised that claim to be able to be able to determine the allergens or substances that are affecting you. The evidence for these tests are either scant or totally absent. This includes the ALCAT, IgG testing, hair analysis, etc. The Allergy Society of South Africa have published a Position Statement on the first two. Other international organisation, including EAACI (European Academy of Allergy and Clinical Immunology) have also made Position Statements on IgG Testing. In South Africa, two companies are marketing this test: Food Detective by Davies Diagnostics and ImuPro by Molecular Diagnostic Services.
These tests have no proof that they have any benefit in predicting the correct foods or substances causing your symptoms: not a single robust study to show that they
ImuPro is a blood test which claims to be able predict which foods make you sick, i.e., cause allergy or intolerances. The test is supported by Patrick Holford – which should already make the consumer concerned about the validity of this test! The company claims: “…the internationally respected ImuPro Food IgG Intolerance Test that can pinpoint food intolerances”.
The facts are: IgG is a valid blood test, but NOT for intolerances or predicting foods are responsible for allergy.
All major allergy societies throughout the world, and allergy experts, have published position statements warning against IgG tests for this purpose.
See the Allergy Society of South Africa’s position statement on this test (and see the references which indicate links to all of the other societies statements). (We have brought this to the attention of the company but they continued to make these claims – makes one wonder of their ethics!)
