Who it's for

Anyone living with persistent tiredness that doesn't respond to rest — and wanting clinical answers rather than vague advice. Targeted at the most common medical causes of low energy.

What you'll learn

Thirty-seven markers built around the biological drivers of fatigue: iron status, thyroid function, vitamin D, B12, cortisol and inflammation. Reveals which system is actually causing your symptoms.

Why it matters

Persistent fatigue is rarely just tiredness — it's almost always a treatable underlying cause hiding in plain sight. Iron, thyroid, vitamin D and cortisol are the most missed culprits. The right test ends years of guessing.

FAQ

Common questions

How do I take my blood sample?

We post you a free venous home collection kit with everything you need — sample tubes, instructions and a pre-paid Tracked 24 return envelope. You’ll need someone trained to draw blood, or you can add a phlebotomist home visit at checkout and we’ll come to you.

When should I take my sample?

Morning is best — most hormones (especially total testosterone and cortisol) follow a daily rhythm and read most accurately before 10am. Avoid intense exercise for 24 hours beforehand so your recovery and inflammation markers read true.

How fast will I receive my results?

Same day your sample arrives at our UK lab. You’ll get a notification when your AI report is ready in your private dashboard.

What if I take the sample wrong?

If you have a problem during collection — the tube won’t fill, you spill it, the cap leaks — message us before you post the sample and we’ll send a free replacement kit. Once it reaches the lab, retests carry a £15 fee, so it’s always cheaper to flag it with us first.

Will I understand the results?

Yes. Every result comes with a plain-English AI report explaining what each marker means and what’s optimal for your age and goals. If you want to talk it through, you can book a consultation with one of our doctors.

Where is my sample tested?

All samples are processed at our own UKAS-accredited UK laboratory, Bloods UK Ltd. We run the lab in-house — meaning shorter chain of custody, faster turnaround, and tighter quality control than third-party processors.

How is this different from a blood test from my GP?

Your GP tests to diagnose illness — we test to optimise your health. This is a focused panel of 37 markers, read against optimal ranges rather than just ‘in range’, with a plain-English AI report that’s yours to keep. Want a wider picture? You can add related markers at checkout or choose one of our full-body panels.

Wherever possible, samples are tested on the same day. Occasionally, testing may take a little longer due to laboratory workflows or operational requirements.
