Have you ordered a Standard Intolerance Test within a month and would like to upgrade to an Optimum Intolerance Test? You can do it here.

You don't have to send your hair sample again, if you have sent it within a month. We can use the same hair sample for testing.

This test is an upgrade only and can not be your first order.

Please note: There is NO free naturopath consultation with the upgrade. It has been included to your Standard Intolerance Test order already.
