Ascia Action Plans Are Essential
On average the nut allergic person will have an accidental exposure every few years. The difficulties of avoiding peanuts, tree nuts or seeds completely make it essential to have an ASCIA Action Plan for Anaphylaxis when an adrenaline autoinjector has been prescribed.
Nut allergy can be effectively managed
Under the supervision of a clinical immunology/allergy specialist and with a network of supportive contacts, people with allergy to peanuts, tree nuts or seeds can learn to manage their allergies. The knowledge that adrenaline autoinjectors are available offers reassurance, but is not a substitute for strategies to minimise the risk of exposure to allergen triggers.
ASCIA is the peak professional body of clinical immunology/allergy specialists in Australia and New Zealand.

Most Familiar: Nut Allergy Blood Test With Your Own Doctor
- Amount of allergens tested varies
- Peanut + nut amounts varies
- Doctor office visit + lab
- Varies. See below for ~$200 estimate calculation.
Consulting with your own doctor directly about obtaining a nut allergy test is certainly a viable option. After all, you and your doctor have an established relationship. And the process is familiar.
However, I very much appreciate the power that, Personalabs, Quest Diagnostics, and HealthLabs.com provides to nut-allergic individuals. I have my own story of wishing I had taken action sooner and ordered a nut allergy test via one of these methods. Getting your doctors buy-in isnt always easy, and you definitely need to be your own biggest advocate. Even the most supportive doctors wont always have serious allergies themselves.
Another thing to consider is the time and cost involved in obtaining a nut allergy blood test through your own doctor. A doctors office visit, a referral for the lab, a lab test visit often times on a different day and at a different location. Insurance. But of course, go with your own comfort level.
What Does The Results Report Tell Me
An allergy test will tell you if you are sensitised to tree nuts or peanuts and how severe it is. Sensitisation means that your immune system produces more IgE antibodies against the allergens in the food.Sensitisation does not automatically mean that you have an allergy. However, if you also experience symptoms after eating certain nuts, you can assume that you have an allergy.

Be Prepared For An Allergic Reaction
Antihistamines should be carried at all times and taken if an allergic reaction occurs. The patient and their carers should be regularly trained in how to use an adrenaline auto-injector or adrenaline in a prepared syringe, and if the device has to be used, the patient must seek immediate medical attention .
Nut Allergy Treatment: Will My Nut Allergy Go Away
At the moment, there is no effective way to cure an allergy to peanuts or a tree nut allergy. Treatment consists primarily of avoiding the allergens. For milder symptoms such as red skin and an itchy mouth, you can take tablets or drops containing antihistamines. These medications are usually available over-the-counter at drugstores.

Severe Allergic Reaction Anaphylaxis
Peanuts and tree nuts are among the most common foods to cause severe allergic reactions. Severe allergic reaction is life threatening. Symptoms of a severe allergic reaction include:
- difficult or noisy breathing
- persistent dizziness or collapse
- paleness and floppiness in young children.
If you, or a child in your care, have a severe allergic reaction , call triple zero for an ambulance. Do not stand or walk . Administer adrenaline via autoinjector , if available.
How Do They Test For Nut Allergies
Doctors screen for allergies with the help of a blood test, for example. A laboratory tests your blood for certain antibodies, group E immunoglobins . These food allergy tests fifind out whether you are sensitized to an allergen that is, whether several IgE antibodies against the allergen are found in your blood. Such blood tests can be done with a doctor, but there are also home test kits that screen for nut allergies.Another way to detect sensitization to nuts is a prick test. In this testing method, a doctor places a liquid extract of the allergen or the allergen itself on your skin and checks for wheals and redness.
A provocation test can provide more certainty about whether you suffer from a nut allergy. Doctors administer a dose of the allergen to you or your child and observe whether a nut allergy reaction occurs. Since dangerous allergic reactions can also occur, this type of test must always take place under medical supervision.
If you find out you have a sensitivity to nuts through an IgE test, this is the first indication of an allergy. However, only physicians are allowed to make a concrete diagnosis you should take your results to them to discuss.

How Do Doctors Test For Food Allergies
How do doctors test for food allergies? Debra
Doctors often use a combination of skin testing and blood testing to diagnose a food allergy.
One common skin test is a scratch test. For this test, a doctor or nurse will scratch the skin with a tiny bit of liquid extract of an allergen . Allergists usually do skin tests on a person’s forearm or back. The allergist then waits 15 minutes or so to see if reddish, raised spots form, indicating an allergy.
If the doctor thinks someone might be allergic to more than one thing or if it’s not clear what’s triggering a person’s allergy the allergist will probably skin test for several different allergens at the same time.
When a skin test shows up as positive with a certain food, that only means a person mightbe allergic to that food. In these cases, doctors may want to do additional testing.
To diagnose a food allergy for certain, an allergist might do a blood test in addition to skin testing. This involves taking a small blood sample to send to a laboratory for analysis. The lab checks the blood for IgE antibodies to specific foods. If enough IgE antibodies to a particular food are in the blood, it’s very likely that the person is allergic to it.
If the results of the skin and blood tests are still unclear, though, an allergist might do something called a food challenge. During this test, the person is given gradually increasing amounts of the potential food allergen to eat while the doctor watches for symptoms.
How Can I Prevent A Peanut Allergy
Feeding infants small amounts of peanut-containing foods can lessen the chances that they will develop an allergy. One study found that 17% of babies who did not eat peanuts developed an allergy by age 5. In contrast, only 3% of those who ate peanuts developed a peanut allergy by age 5.
Always ask your childs healthcare provider for recommendations about feeding your child peanuts. The timing of introducing your child to peanuts varies, depending on if your child has:
- Egg allergies.
- Both severe food allergies and eczema.

How Do You Identify Allergens On Food Labels
Food manufacturers are now required to mark the 14 most common allergens in bold print on ingredients lists. These include peanuts and tree nuts. Suppliers of loose goods, such as bakeries and restaurants, must also provide information about allergens in their products. The statement May contain traces is voluntary. More precise statements such as May contain traces of hazelnuts are rather rare.
Did you know that avoiding peanuts completely is difficult for many people. According to studies, 75 percent of peanut allergy sufferers accidentally ingest peanuts at least once over the course of ten years.
Test Family Members For Peanut Allergy
Between 5% and 9% of siblings of children with a peanut allergy will also have a peanut allergy. In individuals at high risk of an allergic reaction or in cases of parental anxiety, it is advisable to perform skin prick testing or specific IgE testing before the child introduces peanut into their diet. In individuals at low risk of an allergy, peanuts can be carefully introduced to test for any allergic reaction .

What Is The Treatment Of Peanut Allergy
The treatment of anaphylaxis is a medical emergency entailing the stabilisation of airway, breathing, and circulation.
- Intramuscularadrenaline must be given immediately to patients with signs of shock, airway swelling, or definite difficulty in breathing.
- This may be followed by treatment with an antihistamine, a corticosteroid, and other drugs.
Confirmed peanut allergy needs a comprehensive management plan, which should be shared with the patient’s wider family, school, and/or workplace .

Can Nut Allergy Be Prevented
For a long time, experts advised parents to keep young children away from typical allergy triggers such as nuts, even if they had not yet developed an allergy. But new studies suggest that children who eat peanuts at an early age are less likely to develop an allergy.Thats why health authorities in the United States updated their peanut allergy management guidance in January 2018. The new recommendation for parents whose children are considered at risk for allergies because they suffer from dermatitis or an egg allergy is now to include food containing peanuts in your childs diet between the ages of four and six months old. Before that, you should ensure your child takes an allergy test to make sure that your child does not already have a peanut allergy.

Nut Allergy Reaction: What Is An Anaphylactic Shock
A particularly severe nut allergy reaction that can affect the entire body is called anaphylaxis. It can cause a life-threatening anaphylactic shock.
Anaphylactic shock is sometimes, but not always, preceded by warning signs. Those about to suffer an anaphylactic shock might experience the following possible nut allergy symptoms:
- Itching, burning, and tingling on the hands, soles of the feet, and genital area
- Tingling and itching on the tongue and top of the mouth
- Anxiety and headaches
- A metallic taste in the mouth
Children often become restless as well as anxious or aggressive before showing other symptoms.

Unorthodox Allergy Tests Are Unproven
There are several methods of unorthodox tests for food allergy. Examples include cytotoxic food testing, Vega testing, kinesiology, allergy elimination techniques, iridology, pulse testing, Alcat testing, Rinkel’s intradermal skin testing, reflexology, hair analysis and IgG food antibody testing. These tests have no scientific basis, are unreliable and can’t be reproduced. ASCIA advises against the use of these tests. No Medicare rebate is available in Australia for these tests, and their use is not supported in New Zealand.
Adverse consequences may arise from unorthodox testing and treatments. Treatment based on inaccurate, false positive or clinically irrelevant results can lead to ineffective and expensive treatments, and delay more effective therapy. Sometimes harmful therapy may result, such as unnecessary dietary avoidance and risk of malnutrition, particularly in children.
Why Am I Doing This
Today my daughter is having her annual allergy skin testing and our Paediatric Allergist has asked me to bring in these two cakes to perform skin testing with baked goods that contain two of her allergens -egg and milk. So many emotions come up as I bake these cakes and prepare for her appointment:
FEAR: It is frightening to bring these ingredients into the kitchen -coming in contact with my bakeware and utensils. My daughter is fearful of the test but I assured her it was less risky than the usual testing where they use straight milk or egg.
EXCITEMENT & HOPE: Every year I get my hopes up that maybe this year will be the year she outgrows at least ONE of her severe allergies.
Sooooo, I just put a chocolate cake in the oven with a cup of milk in it -I may have licked the spoon and just pulled out the Carrot cake I made with an egg in it -MAN does an egg make a difference! That cake is so light and fluffy -sighIve missed eggs. But I do have to say I can REALLY taste the egg and I only used one instead of the three the recipe called for so I think it would taste really EGGY to me with the regular recipe.

Diagnosis Of Nut Allergies
If you have allergic symptoms, visit your family doctor who will ask some questions about your allergic reactions. You can also discuss your record of your symptoms. To diagnose your allergy, your doctor may refer you to a specialist doctor known as an allergist or clinical immunologist. Allergists can test for allergies using a number of methods, depending on the type of potential allergy. To test for an allergy to peanuts, tree nuts and seeds, the allergist might:
- do a skin prick test
- do a blood test
- ask you to temporarily avoid all nuts or products containing nuts , then follow up with the introduction of nuts back into your diet under strict medical supervision.
Can Peanut Allergy Be Prevented
In 2017, the National Institute for Allergy and Infectious Disease issued new in order to define high, moderate and low-risk infants for developing peanut allergy. The guidelines also address how to proceed with introduction of peanut based on risk in order to prevent the development of peanut allergy.
The updated guidelines are a breakthrough for the prevention of peanut allergy. Peanut allergy has become much more common in recent years, and there is now a roadmap to prevent many new cases.
According to the new guidelines, an infant at high risk of developing peanut allergy is one with severe eczema and/or egg allergy. The guidelines recommend introduction of peanut-containing foods as early as 4-6 months for high-risk infants who have already started solid foods, after determining that it is safe to do so.
If your child is determined to be high risk, the guidelines recommend having them tested for peanut allergy. Your allergist may do this with a skin test or blood test. Depending on the results, they may recommend attempting to try peanut for the first time in the office. A positive test alone does not necessarily prove your child is allergic, and studies have shown infants who have a peanut sensitivity arent necessarily allergic.
Although parents want to do whats best for their children, determining what best means isnt always easy. So if your son or daughter is struggling with peanut allergies, take control of the situation and consult an allergist today.

Does Immunotherapy Work For Nut Allergies
As a peanut allergy sufferer, you can now hope for a cure in the future. Scientists are currently working on oral immunotherapy, whereby patients ingest peanut allergens orally. In one study, researchers gave children with peanut allergies peanut proteins along with probiotics, or lactic acid bacteria. Probiotics stimulate the immune system and are thus thought to enhance the effect of immunotherapy.A total of 67 percent of the children were able to eat peanuts again after treatment none of the children suffered anaphylactic shock for four years following treatment. The study was small, however, with only 24 children participating. Now the researchers want to test their method in larger studies.A recent review study that looked at 12 studies of oral immunotherapy for peanut allergy dampens our hopes somewhat. The risk of a severe nut allergy reaction such as anaphylaxis during treatment is still too high. According to the researchers, treatment still need to be improved and made safer.
Did you know that egg allergy and milk allergy affects mainly young children and disappear by the time they start school? Peanut allergy, however, only develops during adulthood in around 20 percent of those affected.
