Always Tired? A Blood Test Can Tell You Why.

Standard NHS panels often only flag results outside a broad reference range, which can miss suboptimal levels that still leave you feeling exhausted. Our panels test a wider range of markers and are interpreted with your symptoms in mind, not just a pass/fail range.

It depends on the panel — the thyroid profile doesn't require fasting, but if you're combining it with markers like glucose or cholesterol, an 8-12 hour fast is best. We'll confirm this when you book.

It varies by cause — a straightforward vitamin deficiency can often improve within weeks of supplementation, while hormone or thyroid issues may take longer. We'll talk through realistic timelines at your results review.

That's still useful information — it rules out the most common physical causes, so we can look at other factors like sleep quality, stress or lifestyle with more clarity.
