Are at-home allergy tests reliable?

The video discusses the reliability of allergy tests that can be purchased on the High Street or done at home. Dr. Helen explains that while some of these tests are useful and validated, others may not be. In particular, the Immunoglobulin E (IgE) allergy tests are the ones that are reliable for diagnosing allergies, but a negative test result does not necessarily mean the absence of allergy. Positive test results can also be inaccurate, and it is important to consult a professional who can interpret the results and consider the individual's history to avoid false positives and unnecessary removal of food. False positives can also lead to a loss of tolerance to a food. It is therefore essential to seek medical advice before purchasing and using an allergy test.
