The Phadiatop which stands for Phadia Differential Atopy Test is a multi-allergen inhalant allergy screening test — very useful for assessing if inhalant allergy is present in conditions such as asthma and rhinitis. The screening panel has extracts of House dust Mite, Cat and Dog dander, Mould spores, Tree, Grass and Weed Pollen and can be adapted to include locally implicated aero-allergens such allergy Cockroach a problem in North America. The fx5 is the common Paediatric Food Allergy screening test that includes the commonest 6 implicated allergy-provoking foods.
The test is therefore a useful screening test in children when no individual food is obviously implicated or when multiple food allergies are suspected.
In older children and adults, nut allergy and anaphylaxis is an ever-increasing problem. The fx1 is a very useful screen for nut and peanut allergy and the screening panel includes Peanut, Hazelnut, Brazil nut, Almond and Coconut. It does not include Cashew, Pecan or Pistachio nut. In clinical practice, Peanut Cashew and Brazilnut account for most nut allergies but there is a considerable amount of cross-reactivity between the diverse botanical nut families.
In adults there is a seafood mix screen called fx2 which contains Codfish, Shrimp, Blue mussel, Tuna, and Salmon. Screen tests tend to help reduce costs of allergy testing by selecting suspected food groups.

Current issues relating to in vitro testing for allergen-specific IgE.
For this reason an new range of recombinant allergens have been developed to measure specific proteins in food allergy. As a result the unsuspecting Latex Allergy sufferer may have an whar allergic or anaphylactic mix to Avocado, Banana, Kiwi or Chestnut when they eat these for the first time. If the specific allergen is then identified on a blood test, the person can be advised what what foods they may react to and what foods to avoid.
These recombinant allergen tests are however very expensive and iss needs to do a vast number of specific tests to identify the major allergens. One or all of which could be the potential cause of an egg allergic reaction. Silver Birch pollen derived allergenic components include 5 different Bet v proteins including Profilin and LTP allergy cross react to various stone-fruits and nuts.

In Peanut we find 9 different Ara h allergens and in Latex 13 different Hev b allergens any of which could be the specific cause of Latex allergy. It is useful for patients with peanut allergy and latex allergy where identification of the individual components has clear implications for the treatment and the prognosis. That mic therefore tests in total, covering different natural allergens.
This much greater allergen panel is therefore not only useful for researching individual allergens for individual patients but is also a comprehensive and definitive allergen screening test for suspected allergic patients. Skin testing is cheap, safe, and easy to do and someone in a GP practice can easily be trained to perform it. Commercial inhalant allergens are readily available, but food allergens are a little more difficult to fish. The main problem with food allergens is the on of stability of extracts.
However, fruit and vegetable allergens are very unstable and fresh testing should be used. Infants can be skin tested for food allergy from 4 months of age. For this reason, for fruit and vegetable allergens, we tend to use the Prick plus Prick testwhere we prick the offending food, gather some sap and then prick tesging patient with the fresh extract.
They can also be very expensive and blood has to be sent to specialised immunology laboratories to be processed. This is why we rather discourage allergy screening in otherwise healthy individuals fish the whah may be misleading.

Then contact allergh made with the eyelid or lip. Next allergy are placed on the tongue and mouth membranes, until finally an amount of un food is consumed without reaction. Each step of the allergy challenge what place under close jix supervision at minute intervals. The allergy challenge test trsting immediately stopped if an adverse reaction is detected at any testing.
Experienced medical staff and full resuscitation equipment should always be readily available. Challenge testing should never be done jn home without an Epipen readily available.Fish Allergy | Food Allergy Research & Education
