Not All Allergies Can Be Diagnosed By An IgE Test


A recent study by Southampton Children’s Hospital has cautioned that tests to detect food allergies in children could be missing many potentially life-threatening conditions. Experts have warned that for every child diagnosed with an allergy via blood or skin prick test another goes undiagnosed.

A specialist paediatric dietician Dr Kate Grimshaw at the Hospital said that not all allergies can be detected by measuring levels of immunoglobulin E (IgE) antibody which is linked to allergic reactions. Her advice comes as new research into cow’s milk allergy found that for every UK child who had a cow’s milk reaction due to IgE in their blood there was a child who had a reaction who did not. The same advice could relate to adults as well as children.

Marlene @ the Devon Allergy Clinic who has a Diploma in Allergy has long advocated that to properly diagnose an allergy the testing by IgE pinprick or by a diagnostic machine is insufficient to arrive at a clear result. Just as important is the taking of family history notes & discussion of all symptoms presenting themselves with the patient.

Hair Dye & Henna Tattoos Can Cause Allergic Reactions

Doctors are warning that the trendy henna tattoos and hair dyes are increasingly causing allergic reactions among children.

Hair dyes and henna can contain chemical para-phenylenediamine and the trend for henna tattoos and hair dyes ‘are to blame for a rise in allergies and painful eczema. The chemicals can trigger allergies that result in contact eczema and although the use of of PPD in black henna tattoos is banned in the UK and elsewhere in Europe, it is still easy to get in other countries

Just one use of black hair dye or henna that includes the chemical para-phenylenediamine can create an allergy which results in painful eczema.

Data gathered over 20 years by dermatologists in Leeds suggests that 27 per cent of children suffer from contact eczema, an allergic reaction which can result in an itchy and painful rash.

But over the period the experts report a shift in the substances that they are reacting to.

A study presented recently at the British Association of Dermatologists annual meeting in Manchester cited the number of children reacting to nickel since its use was restricted across Europe in the 1990s.

But the overall number of children being seen with skin allergies has stayed the same, because the use of other substances have increased.

Experts are particularly worried about the use of para-phenylenediamine – or PPD , which is widely used in hair dye, particularly in black and dark brown colours.

More efforts need to be made to make people aware of the sensitising properties of common substances. For more information, or to find out how I can advise you if you have been affected, contact me for a chat.
