What accurate allergy blood tests are available?
There is the original old Total serum IgE blood allergy test, which has been superseded by the newer multi-allergen screening tests. The inhalant allergy screen is called a ImmunoCAP Phadiatop, then there are various ImmunoCAP food allergy screening panels such as the fx5 for common paediatric food allergens, fx1 for nuts, fx2 for seafood’s and fx3 for cereals. There are over 450 individual RASTs available for everything from sheep dander to sesame seeds. These are now called Immunocap RAST tests by Phadia(UK).
