Sometimes, no matter how healthy your food is, it can make you sick. Intolerance tests allow you to better understand your body’s sensitivities and enable you to live a compromise-free life. Intolerance tests are safe and usually use the skin prick method to collect a sample for testing.

An intolerance test is an inexpensive way of understanding your body’s chemistry. Food intolerances are not permanent and will fade away on their own, but travelling with an unknown allergy or intolerance can prove to be very costly. When travelling, you will eat different foods, some of which aren’t prepared with the same ingredients that your body is used to, which could result in food intolerance.

The more you eat a food that you’re intolerant to, the more severe your symptoms will manifest. So, let’s say you go without knowing that you’ve become intolerant of your favourite food, you will keep having intense symptoms. If you eat a little of the food you’re intolerant to, the symptoms won’t be as fierce. The symptoms will become more intense if you increase the quantity.

Medical care and hospitalization abroad can cost you thousands of pounds, making an intolerance test a must if you’re a frequent traveller or just as a precaution. So, where can you get a quick intolerance test?


Intolerance Test Kits

Food intolerance takes time to manifest. It can take a few hours up to days to see the symptoms. By then, you have already eaten other foods, and you won’t know exactly which one of the many meals you’ve had has resulted in intolerance. Blood tests are used to check for intolerance and test the level of IgG antibodies in your system because when your body is fighting something it considers “harmful” it produces these antibodies. The sample you send back to the lab is tested against various common foods known to cause intolerance, then the doctor’s know the results through the number of antibodies your blood fights back using.

Immunoglobulin G (IgG) can help diagnose whether an individual is allergic to certain food products [1]. The medical field has come up with inexpensive intolerance test kits that can provide quick and convenient testing.

Intolerance test kits can be bought online or through NHS-approved retailers. Healthcare companies like Test Your Intolerance use innovative methods to test a single blood sample for more than 100 different allergy tests, providing you with a comprehensive profile of your allergen tolerances. The kits safely store your samples so that they are free from any unwanted microbes, and medical professionals can then run different tests to diagnose your allergies or sensitivities.
