Frequently Asked Questions
Is this real ELISA plate laboratory testing?
Yes, Smartblood use the established ELISA plate testing method to accurately detect IgG antibody reactions to over 134 food and drink ingredients. There is no doubt that using ELISA plate techniques yield reliable repeatable results. View our scientific studies page for more information.Is this "bioresonance" or some other such mumbo jumbo?
No, this is absolutely NOT bioresonance testing. Our position is that such techniques have no lawful basis in food intolerance testing. Some bioresonance providers clearly state their method, others do not - if in doubt, please call our customer care line on 01392 539444.I've been told that Smartblood only test IgG subclass 4 antibodies, and not all IgG Subclasses. Is this correct?
No, this is not true. Smartblood tests whole IgG antibody reactions. Whilst IgG subclasses do exist, any talk of them in relation to IgG food intolerance testing is probably a result of over zealous marketing.Can the Smartblood Food Intolerance tests be taken at home?
Yes, both the First Step Test and the full Smartblood Food Intolerance Test can easily be carried out, by yourself, at home, or at work. A very small amount of blood is needed, full instructions are given, and a return envelope is provided so that you may return your sample safely to our Laboratory.Is there a minimum age for Smartblood Food Intolerance Tests?
The minimum age we recommend is 24 months due to an undeveloped immune system.What medications can affect test results?
Both Steroids and Immunosuppresants may affect results – please let us know if you are considering taking the test whilst on these. We will never suggest you stop taking these drugs.Videos that help explain the Smartblood Process.
