Pharmacist’s Letter issues warning about Hemocode food intolerance testing
From the December, 2012 Canadian Pharmacist’s Letter (paywalled, sorry), a subscription-funded, completely independent resource for pharmacists, comes a warning about the Hemocode food intolerance test:
Patients are hearing misleading claims about the Hemocode test for food intolerance. This test is NOT proven to help…and it could cause problems.
Hemocode isn’t the first lab test for food intolerance. But it’s becoming more popular now that the test kits are being sold in some pharmacies…and advertising is directed at consumers. But a positive IgG reaction to certain foods does NOT necessarily mean intolerance. In fact, positive test results to IgG antibodies are EXPECTED…because they’re markers of exposure to those foods.
Their bottom line?
Tell patients to save their money…these tests usually cost between $450 and $700. Have patients see an allergist if they’re concerned about food allergies…and explain that so far there’s no proof that IgG testing can diagnose food intolerance.
For more information about the scientific evidence of food intolerance testing, and the lack of utility of IgG blood tests, see:
