Allergy & Intolerance Test FAQ

This is a HUGE topic and I have answered much in the free Allergy 101 Factsheet for you. Meanwhile, here are some common questions - I'll build this as I get questions in for you..


Q: Can I do allergy or intolerance testing for my child?


A: It depends on their age really and the type of testing you are planning.


IgE classical allergy testing can be done reliably from about 9 months onward. This is because babies do not have a fully developed IgE response until about 6-12 months. The same therefore goes for reliable skin prick testing in my view as that is looking for IgE responses too.


The usual issue with blood tests for little ones is getting the blood. For these tests to be processed the lab needs 1 full serum tube (8-10ml) of blood which can be challenging to draw from children as young as 2 or 3 years old. Some phlebotomy clinics are reluctant to take blood draws from children at such a young age.


The FACT cellular Genova tests are not suitable for children under the age of 2 years old.


ALCAT testing is suitable for any age, the lab says, as long as you can get enough blood.


Cyrex testing is suitable as long as they are eating gluten or the allergens being tested, but the issue is with getting enough blood as per. 


York IgG tests, children must be over two.


Alletess IgA/IgM/IgG tests state a minimum age of 12 months, although I would say 18 months to 2 years is probably more reliable.
