I am pleased with the blood results as it highlighted allergies that I knew I already had since a young child (increasing the validity) and also new food allergies that I did not know I had.
I am looking forward to eliminating these foods from my diet!
Hannah F
Foods eliminated
I have eliminated the foods that you recommended and have been thrilled to add back some foods that I previously thought were problems for me.
I feel so much better! I have recommended your testing to many people. Thank you!
Riva V
Happy mum
My mother has been having some stomach issues and wanted to find out exactly what was wrong, the doctors couldn’t tell her.
Now my mom can make those subtle food changes and have a much happier stomach and not be questioning everything she eats!
Helena S
Surprised to find out...
I received my results by email and I’m very surprised to find out that I have an intolerance to pretty much every nut.
I also have a high intolerance to barley. I can now cut these out of my diet and hopefully my reactions will be a thing of the past!
Richard K
So easy to do!
The test was so easy to do from reading the instructions, quick and easy delivery, great customer service!
Great way of testing if you are like me and frightened of blood tests!
Nadia
Got my results fast!
Kit was very easy to use and send back, even to getting the results, everything was very fast.
According to the test, I have 9 allergies and 14 intolerances. Overall, it was really straightforward and I was quite surprised at some results.
Sam
Couldn’t be simpler!
This home testing kit couldn’t be simpler! Quick finger prick, put the samples on the card provided and post it off!
I got my results 4 days later, and I now have a list of foods I am intolerant to that I can avoid in my diet.

Frequently asked questions
Allergy & Intolerance Testing
Allergies
An allergy is an immune system response. It is caused when the body mistakes a protein as a harmful substance and creates a defence system (antibodies) to fight it.
Allergic reactions are immediate reactions, and they can be life-threatening in some cases.
Intolerances
An intolerance is a non-immune system response. Symptoms of intolerance usually occur several hours after exposure to a trigger, whereas an allergy can result in an immediate reaction.
Often people need to be exposed to larger amounts of food types to trigger an intolerance unlike an allergy. A food intolerance is not life-threatening.
We have IgE ELISA food and non-food allergy testing. IgE antibodies are involved in Type I allergies and can cause rapid type immune reactions, with symptoms occurring within a few minutes up to two hours after eating a specific food.
We provide you with easy-to-use lancets designed to give you a tiny prick on the finger to start the blood flow.
It’s precisely the same as a pinprick and, if administered correctly following our provided instructions and tips, will not hurt.
While we allow children from the age of 2 and above for blood allergy and intolerance testing.
There is evidence that allergies are not fully developed until the age of 7. Please check with a medical professional before purchasing.
There are a few types of medication that may stop your test from being accurate.
Immune suppressant medications can also affect the results of the testing, we advise that you check with our team prior to testing regarding medications.
Antihistamines have been shown to affect results; we advise stopping antihistamine use for 3-5 days before taking your sample.
However, we would recommend seeking advice from a medical professional before changing any medication.
Sensitivities include all those reactions to food and non-food items that can activate a non-immune mediated response.
Instead they can be caused by not having the right enzymes you need to digest certain foods or a reaction to food additives or preservatives.
The safest way to take a hair sample is to ask someone else to help you. Using your forefinger and thumb, gather 3 or 4 strands and slightly twist the hair together.
This will make cutting the hair sample much more accessible and keep all the hair strand in the same direction.
Try to cut the hair sample as close to the scalp as possible, using one cut. If you do not have anyone to help you, using a mirror may help ensure you avoid injury.
If you have purchased a kit and not selected to Go Green and Save option at checkout, then you will receive a kit in the post. This is sent out to the address provided at the time of purchase, with tracked Royal Mail post. We will send your tracking via email.
If you have selected the Go Green and Save option, you will not receive anything in the post and instead you’ll receive an email to submit your details digitally online. If you need this resending, please reach out on LiveChat.
The hair sample does not have to be from the head, we can test hair from any part of the body, including leg, arm or chest.
The test is completed on the hair sample composition so that no hair processing will not affect the result. However, if you would like, you can provide hair from elsewhere on the body.
Children can complete a hair sensitivity test once they reach five years old due to their immune system changes and the importance of eating a varied diet.
Infants have not yet built up their tolerance levels to items, highlighting false positives in their test results.
However, it is up to the parents or guardians if they would still like to proceed knowing this.
If you’ve purchased one of the sensitivity tests, you will have to pay the postage cost back to the processing centre, which then sends the sample to the UK.
We try to keep our costs as low as possible (by not sending out physical hair testing kits) so that we can offer such a comprehensive test at the price offered.
Please ensure the correct postage amount has been paid as we are not liable for any extra charges.
Although the products can vary for different regions, we currently have an extensive range on offer. We have liver function testing, vitamin D at-home blood testing, prostate, persistent inflammation, thyroid, menopause testing, urine kidney testing, inflammatory bowel disease testing, ovarian and colon testing. All are available at-home, with immediate results.

A strict quality assurance process combined with myDNA’s state of the art laboratory facilities allows handlers of your DNA to control the reliability and validity of the tests.
