About Us

The Smartblood Laboratory
Elisa plate testing

User Friendly, Reliable, Fast and Trackable.

We created Smartblood with a view to building the world’s first user friendly, reliable, speedy and trackable food intolerance testing service.

We passionately believe that the elimination of foods based upon IgG antibody testing, when combined with the support of a qualified nutritionist can help to alleviate a number of conditions. Our position is supported by published scientific studies as well as feedback from our patients, and also the experiences of our experienced BANT registered Nutritional Therapists who have completed thousands of food intolerance consultations between them.
