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.

Very helpful information. I've recently reacted badly to an apple, and been eliminating food unsuccessfully for for 15 years in an attempt to reduce IBS. I had been refused allergy testing several times so I bought an IgE + IgG4 test. I had a lot of positives, but did follow up with their nutritionist. Im glad I did as the results alone couldn't help me make the right changes to my diet. Based on the results and her advice, my GP is finally referring me to an allergy clinic. I also learned more about cross related allergies, which is why I can’t eat most fruit and veg, and reacted to the apple. I knew since young that I had a milk allergy but... The real kicker was finding that I had a higher reaction to gluten (oats), soy, rice, and almond... all the alternative milks I had been using for years! Three days of making adjustments and the supposed IBS had gone! I would recommend testing but only to gain medical and nutritionist support, when all else fails.
