‘Alternative’ allergy tests

19/06/2015 //  by Michelle Berridale Johnson//  2 Comments

Sense About ScienceSense About Science is a scientific charity whose remit is to inform the public and enable them to ‘make sense’ of scientific and medical discussions. A worthy aim in which they are usually moderately successful. However, they have just tackled allergy and, although they have recruited the best ‘experts’ and covered the subject very comprehensively, I suspect that the allergy virgin might go away a good deal more confused than they started! Not SAS’s fault but, the more we discover about allergy the less we actually seem to understand…

Anyhow the paper is well worth a read if you want to bring yourself up to date with the latest thinking. And slightly to my surprise, since they are coming from a strictly conventional medical standpoint, they made very few points with which the more ‘alternative-minded’ could take issue. But, inevitably, one of these was the much disputed area of allergy tests.

The discussion about ‘allergy testing’ is always bedevilled by semantics. While the term is understood by medics to refer to testing for immune-sytem related, ‘true’ allergies, the wider public use it for any test which might tell them what substance (usually a food or drink) is making them feel ill.

The discussion is further complicated complicated by:

1. The fact that even the medically ‘approved’ tests to diagnose IgE mediated ‘true’ allergy (skin  prick and blood tests) are widely recognised to be seriously flawed and are really only useful as a back up to a clear history of allergic reactions.

2. The fact that conventional medicine can offer no tests at all that will diagnose sensitivity/intolerance.

3. That many alternative practitioners can be very hazy about the difference  between a immune-system related allergy and an intolerance or sensitivity which can make the patient extremely ill, but will not cause a reaction which, in very rare cases, could prove fatal.

So the SAS paper lists Applied kinesiology, cytotoxic tests (ALCAT, FACT etc), Food specific IgG tests (York tests), hair testing, NAET and vega tests as being dangerous and to be avoided at all costs. As indeed they are if you think that you have a true, IgE-mediated allergy that could trigger your immune system into a violent and possibly even fatal reaction. However, if you feel like death, you have been referred for skin prick and/or blood tests and they have proved negative and your GP has run out of suggestions, any sort of test that offers you some sort of answers must be appealing.

What many of these tests do, especially those which rely on energy medicine (vega tests, NAET, kinesiology) is to measure disturbances or blockages in your energy pathways and to try to establish whether that disturbance is greater when you are in close contact with a specific food, drink or other substance than when you are not. If it is, then the assumption is that that excluding that particular food, drink or substance from your diet or your environment might be beneficial. If you accept the precepts of energy medicine then this is not an unreasonable assumption.

The danger is, of course, that if you are really unwell, you may react to all kinds of foods etc and that you could seriously restrict your diet – but, if your digestive process is seriously compromised for whatever reason, then a very restricted diet may be just what it needs.

In any case, the only true test of intolerance  is ‘exclusion and challenge’ – excluding the food or drink for limited period of time, seeing if your symptoms improve, then re-introducing it and seeing if your symptoms get worse. The crucial element is for both the therapist and the patient to use their common sense. A highly restricted diet for a week is not going to do anyone any harm – a highly restricted diet for six months or a year might well. So if the restricted diet produces no benefits and the patient feels no better after two, or an absolute maximum of three weeks, then it should be discontinued and an answer sought either with another food or in an entirely different area altogether.

In fact, a ‘challenge’ is the only really reliable test for a true allergy also. But, because of the inherent dangers in getting someone you believe to be allergic to a specific food to actually try eating it, challenges can only be carried out under controlled medical conditions – an expensive option so rarely on offer. But even here, an application of common sense is vital.  I have heard of ten-year olds whose lives are extremely restricted by ‘allergies’ to peanuts, milk and eggs. But these kids were diagnosed by skin prick tests when they were infants, have never suffered an allergic reaction to these foods, and have never been ‘challenged’. Given that 40-80% of children who ‘test’ positive to peanuts, do not react to them, this seems to be just as inappropriate and unnecessarily restrictive diet as any suggested by a Vega or a NAET practitioner!

The last section of the paper, Allergy Myths, deals with a whole range of myths which surround allergy – with very little basis in fact – including claim that either raw milk or A2 milk can ‘cure’ allergies. While either of these milks may be better tolerated by those with compromised digestions than standard, pasteurised A1 milk, all milks, be they raw, A1, or A2, contain the proteins that trigger an allergic reaction so must be avoided by anyone with a cow’s milk protein allergy.

Mind you, I did take exception to the suggestion that you should avoid ‘raw’ milk because you can get E.coli poisoning from it…. A suggestion hotly disputed by raw milk supporters who maintain that ‘raw’ milk has a shiningly good record as far as all bacteria are concerned. See the figures from the US quoted here.

    Hi Michelle, Our 3yo daughter had an anaphylactic reaction to dairy at 5 months, and at the subsequent skin prick tests, her results showed her as allergic to peanuts (very high reading), treenuts, egg yolk, egg white, soy (since outgrown at 2.5yo). I would love to read the information re 40-80% of peanut spt positive kids not reacting to them. We have an appointment with our new allergist next month (recently moved interstate) and I would love to take some information to her, as I desperately want to do everything I can to try and get our daughter to a situation where her allergens aren’t life threatening. Thanks so much, Mel Happ, Australia.

    Hi Mel – Well, if your daughter had an anaphylactic reaction to dairy then she is definitely allergic, whatever the skin prick tests had said!! Hopefully, though, that is one that she may grow out of.
    Th figure re the testing was quoted in the Sense About Science document I was writing about but I have certainly heard it quoted elsewhere. As you will have gathered, the only really reliable test for allergy is a challenge test, if you can persuade your allergist to do one. (They are often reluctant because they need to be done under carefully controlled conditions and are therefore expensive.) If she does not react then inducing/strengthening her tolerance by a eating a limited number or peanuts/treenuts regularly would, under the new way of thinking about allergies, probably be the route to follow – but you would obviously need to be guided in that by your allergist.

A food fad won’t kill you – an allergy will

There has been a predictable outcry in the allergy world this week’s in response to Rachel Johnson’s piece in Thursday’s Evening Standard on ‘dietary requirements’ and food fads. Being charitable, I am assuming that she has never suffered from or lived with someone with a food allergy. However, I do have some sympathy with her …

Bioplastics – a solution or part of the problem?

Everyday Plastic is a social enterprise group using accessible learning and publicity campaigns to reduce the amount of plastics used daily in our society. It was founded by its current director Daniel Webb who, having moved to Margate in Kent in 2016, was horrified to discover that there were no plastic recycling options on offer.  …

Do not extradite Julian Assange to the US

Julian Assange is being sought by the current US administration for publishing US government documents which exposed war crimes and human rights abuses. The politically motivated charges represent an unprecedented attack on press freedom and the public’s right to know – seeking to criminalise basic journalistic activity. Assange is facing a 175-year sentence for publishing …

What to believe – applying critical thought

For the average citizen evaluating the claims made for cure all – or even improve all – health products and procedures has always been difficult. Not only is it an area in which we have minimal expertise but most of us have a vested interest in finding a miracle intervention that will solve our health …

Could wireless monitoring devices be killing racehorses?

Regular readers may remember that back in August last year I alerted you to a posting on Arthur Firstenberg’s Cellphone Task Force site about phone masts and bird flu. Could there be a connection between the fact that the two wildlife sites in Holland and Northern France which had suffered catastrophic bird flu deaths were …
