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

Great way of testing if you are like me and frightened of blood tests!

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.
Once you have purchased our test you will receive an email to submit your details digitally online.
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.
Blood and DNA kits are sent out to the address provided at the time of purchase, with tracked Royal Mail post.
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.

Please ensure the correct postage amount has been paid as we are not liable for any extra charges.
