I may recommend functional testing to confirm or rule out a driver for a particular symptom. For example, tests may look at your levels of specific nutrients or hormones or they may assess the function of particular systems in your body, for example your digestive function.
Tests that I recommend from a private lab can usually have samples collected by you at home which are then sent off for analysis. I can arrange these tests for you. Any functional testing with a private lab incurs an additional cost to your consultation.
There are some tests which you can request from your GP, and I will recommend these where appropriate.
