Stop guessing why you feel so tired
Ongoing tiredness usually has a cause you can measure. An underactive thyroid, low iron, low vitamin B12 or vitamin D, a raised blood sugar or a hidden infection can all leave you drained. This test looks at each of them in one go so you know where you stand.
Answers, not a shrug
Instead of being told you are just run down, you get measured results across the systems that commonly drive fatigue.
A report you can read
Your results come with reference ranges and plain-English notes, with anything out of range flagged so it is easy to spot.

Worth checking if you recognise these
This test is a sensible first step if tiredness has been hanging around and you want to know why.
Persistent or severe fatigue should always be reviewed by a doctor. This test helps find a cause; it does not replace medical assessment.

Difficult veins? We find them with ultrasound
If you have fragile or hard-to-find veins and have had failed attempts before, our consultant radiologists can take the sample under real-time ultrasound. It is the only such service in South Wales, and patients travel to us from across Wales and the West for it.
Nobody had managed to take my blood in years without several attempts. Here it was done first time with the ultrasound. Such a relief.

Common questions about the fatigue blood test
How much is the Tired All The Time blood test?
£210 all inclusive. That covers the blood draw, all the panels listed above, and a plain-English report emailed to you. A £50 deposit secures your appointment and comes off the total.
What does this test check for?
It looks at the common medical causes of ongoing tiredness: thyroid function, iron levels, vitamin B12, folate and vitamin D, a full blood count, blood sugar and diabetes markers, kidney function, and a marker of inflammation.
Do I need a GP referral?
No. This is a self-refer test. Book online or call 029 2199 9300.
Do I need to fast before the test?
For the most accurate glucose and diabetes results we usually recommend fasting for around 10 to 12 hours, with water allowed. We will confirm exactly what to do when you book.
How quickly will I get my results?
It depends on which markers are in your test. As a rough guide, results take anywhere from a few days to a couple of weeks. Ask us when you book and we will give you a clearer idea for your test. Your report lists reference ranges with any out-of-range values flagged.
Where is the blood taken?
At our Penarth clinic (13 Washington Buildings, CF64 2AD) or our Cowbridge clinic (10 High Street, CF71 7AG). Both are a short drive from Cardiff with easy parking.
I have difficult veins. Can you still take blood?
Yes. Our consultant radiologists can take the sample under real-time ultrasound, the only such service in South Wales. Mention it when you book so we can allow time.
Can a doctor talk me through my results?
Yes. You can book a private GP appointment and one of our doctors will go through your results and next steps.
Will this test tell me exactly why I am tired?
It checks the causes that show up in blood, which is where most reversible causes of fatigue are found. If your results are all normal, that is useful too, and a GP can help you look at other causes such as sleep, stress or lifestyle.
Want a doctor to explain the results?
You do not have to make sense of the numbers on your own. Book a private GP appointment and one of our doctors will talk you through what your results mean and any next steps.

Important: Blood test results are most useful when reviewed by a doctor who knows your history. We recommend discussing your results with your own GP, or booking a private GP appointment with us, before acting on any findings. Persistent tiredness can have many causes, and this test does not replace a medical assessment. Lab values alone do not constitute medical advice.
