About the tests

  • What is a blood test?

    A blood test is a scientific examination of a sample of blood. Our test measures the presence of IgE (allergy) and IgG4 (intolerance) antibodies to specific allergens using a modified Elisa in-vitro technique.

  • Why are your blood tests more expensive than hair tests?

    Blood testing is usually a much longer process than hair testing, and our staff have to be fully trained to handle biological samples, and ensure the appropriate kits are sent out to clients for the collection of their sample. The blood must be stored appropriately on arrival and it is more time sensitive as blood biodegrades quickly. For this reason, we recommend once you have taken your blood sample it is very important to send this back in the postage paid envelope the same day.

  • What’s the difference between blood and hair testing?

    Hair testing is a type of holistic therapy which measures subtle energies to make a diagnosis, whereas, blood testing is a more in-depth test which produces results based on in-vitro diagnosis.

  • What do you test for?

    Our tests measure antibodies in the blood of the patient, which show if the patient reacts against specific foods and allergens.

  • How soon will I receive my test?

    You should receive your test kit within 3 working days after purchase. Once your sample arrives back to our lab your results will be ready within 5-7 working days.

  • Are your tests just for food?

    No we also include non-food items are included on our Complete Body Test.

  • What happens to my blood after you have tested it?

    All biological specimens are put into Biohazard waste and is incinerated – this happens immediately after testing.

  • What do you do with my DNA afterwards?

    All biological specimens are put into Biohazard waste and is incinerated. We do not keep any DNA anywhere in our laboratory.

  • I haven’t received my kit yet. When should I get in touch to let you know?

    If you haven’t received your kit within 3 working days of ordering, please contact us for assistance – you can contact us via email or LiveChat.

  • I’ve lost my instructions. Can you send me some more or can I download them?

    All instructions are detailed on the website. Alternatively feel free to contact us either via LiveChat or email and the team will advise you on where to find the detailed instructions.

  • Does my kit expire?

    We recommend using your kit within six months of receiving it. There are not really any specific lifespans of the contents, but the alcohol wipe may start to dry out after 12 months from manufacture.

  • Can I buy a test for someone else?

    Lifelab Testing kits can be given to anyone as a gift, we don’t need to know their details upfront. Each of our kits contains a unique code that our customers can register online to create their account. This way, they can receive their test results without providing any payment details.
    You can have the kit delivered to your address or send it directly to the recipient. (Please note: at the moment, kits can only be delivered within the UK.)

  • Can I buy more than one test?

    Yes, you are welcome to purchase however many you require.

  • What payment methods do you accept?

    Visa, Visa Electron, Mastercard, Maestro American express and PayPal – all methods can be seen at the bottom of the website.

  • What are the benefits?

    A Lifelab Test can offer many benefits. It is important to know if you are allergic to foods/non-food items and our tests can identify this for you. A hidden food intolerance/allergy can leave you with many uncomfortable symptoms, so it is very important that you know what foods are triggering your symptoms as this could lead to long-term health problems.
    We can provide results within 14 working days, as we work fast and efficiently to get you the help you need.

  • Why don’t you test for Gluten? – We do on other tests.

    We do test for gluten intolerance (IgG4). We do not test for gluten IgE allergy as in our experience this is rarely seen. It must be noted that gluten IgE allergy is not the same as coeliac disease, this is an autoimmune condition and if you suspect you may have coeliac disease we strongly recommend you seek advice from your GP.

Taking the tests

Test results


  • What’s the difference between an allergy and intolerance?

    People often get confused between a food allergy and a food intolerance. A food allergy is different from food intolerance. A true food allergy causes an immune system reaction that affects numerous organs in the body. It can cause a range of symptoms. In some cases, an allergic food reaction can be severe or life-threatening. In contrast, food intolerance symptoms are generally less serious and often limited to digestive problems and can change depending on diet and lifestyle.

  • Do you test on children’s blood?

    We do not test children under the age of 5 years old. This is because your child has yet to build up their intolerance levels, so the results may not be accurate.

  • Can I do this test on my baby? Age?

    We do not test children under the age of 5 years old. This is because your child has yet to build up their intolerance levels, so the results may not be accurate.

  • What if I’m on medication?

    The only medication which may affect results are immunosuppressant medications. Anticoagulants may also affect the conduction of the test. If you’re unsure as to whether your medication will affect your results, please seek advice from your doctor, or a member of our dedicated Customer Services team who are available on LiveChat 24 hours a day, Monday-Friday

  • Do I have to get a doctor to take my blood sample?

    No - this test is designed to perform at home and you can watch a step – by – step video here: https://www.youtube.com/watch?time_continue=5&v=AiY-zo94hdg

  • Why do you extract the plasma from my blood?

    The test is designed to work on plasma only, we find that it is a very effective way to perform the testing.

  • Does your test replace a GPs?

    We do not advise that you replace your medical history or doctor’s prognosis with these results. A Lifelab test is designed to complement a doctor’s opinion, not replace it.

  • Can I have a test if I’ve had a recent tattoo?

    Yes, a recent tattoo will not affect your blood sample or results.

  • Do you have to be eating the foods to have the test?

    The development of IgE (allergy) antibodies occurs after first contact with a food. The evidence around the development of IgG (intolerance) antibodies is less clear cut. If you are unsure about this we advise that you seek assistance from our Customer Service team, who will be able to connect you with a nutritionist to help you further.

  • Can you take the test if you have a blood born disease like HIV or hepatitis?

    No, please do not take our test if you have any blood born disease.

  • Can you take the test if pregnant?

    The allergy triggering potential of the immune system may also be heightened during pregnancy with the shift to an allergy type immune response. You can do, but we would suggest that results may be varied as the body is working so hard during pregnancy. We would advise you to wait until after childbirth.
