Do you feel exhausted no matter how much you sleep? For many people living with chronic fatigue or fibromyalgia, standard blood tests come back completely normal — which can be more frustrating than an actual diagnosis.
That's where the Organic Acids Test (OAT) comes in. It's a functional lab test that uses a single urine sample to assess how efficiently your body is producing energy at a cellular level, alongside gut yeast overgrowth, oxalate levels and nutrient status — all things that can quietly drive fatigue and body-wide pain, and that routine NHS bloods simply don't screen for.
At The Better Living Clinic, this is one of the tests we come back to again and again for clients with unexplained fatigue and fibromyalgia, because it gives us somewhere concrete to start rather than another "everything looks fine."
A quick note: this is a functional test, not a diagnostic one. We review every result with you in detail, and it's designed to work alongside — never replace — your GP or specialist care.
If August has left you more exhausted than your holiday should have, this could be a good next step. Message us to find out more or book your Organic Acids Test.
