It is well known that the standard 2 tier testing used by the NHS is very poor and is estimated to produce upto 40%+ false negatives. The only way to go is private, I have been using Armin Labs, there are other good private tests out there as well.
Tests with Armin Labs can be arranged through myself or go to www.aonm.org/
Functional DX is just awesome, I have not seen anything like it before, just the basic test analyses 54 blood markers and then analyses the relationships between them to reveal a huge amount of information about health trends and what areas are most important to look at. www.functionaldx.com My comprehensive analysis is 60 pages long. Tests are can be ordered through me or practitioners can register themselves.
Other tests coming soon - KPU, Parasites, MTHFR, Post Provocation urinary analysis, live blood analysis
