You’re not imagining it and you’re not making a fuss. Daily exhaustion, dizziness when you stand, aching joints — that’s a story worth thirty minutes and a proper look.

That matters, because whether a result is right for you depends on three things a range can’t see: where in the range it sits, what your other results are doing alongside it, and what is actually happening to you day to day.A ferritin scraping the bottom of the range in a woman with heavy periods and daily exhaustion is not the same finding as the same number in someone who feels fine. A thyroid result at the edge of normal alongside cold hands, weight change and hair loss is worth a conversation.And some things won’t show up unless somebody thinks to look. A 2025 audit of nearly 17,000 primary care requests for tiredness found ferritin was requested in only 9.4% of cases and coeliac testing in 3.2% — yet when ferritin was measured, a quarter of results came back abnormal.1None of that means your previous results were read wrongly. It means ten minutes is not long enough to do it, and a text message is not a way to explain it.Where in the rangeTwo people can both be told “normal” and be in completely different situations. The number matters, not just the label.The picture togetherOne result on its own tells you very little. Read alongside your other results and your symptoms, it can point somewhere specific.What wasn’t testedSeveral common causes of ongoing tiredness aren’t on a routine panel at all. They only get found when somebody asks.Time to explain itA result you don’t understand isn’t a result. Ours are talked through with you, then written down.Sound familiar?What we hear, almost word for wordIf more than a couple of these are yours, the free call is worth ten minutes of your evening.“I wake up tired and by two in the afternoon I’ve got nothing left.”“My head swims every time I stand up too quickly.”“My heart’s racing and I’m sitting still.”“I ache everywhere and it moves around.”“They said my bloods were normal. That was the whole conversation.”“I got a text. Nobody explained anything.”“I asked for a follow-up and got offered one in six weeks.”“I’ve stopped mentioning it because I sound like I’m complaining.”You’re not being dramaticYou’re tired, and nobody has sat down and gone through it with you properly. That’s what the thirty minutes is for.What’s in the panelThe “Tired All The Time” review — every test, and what it’s forBuilt around the first-line investigations NICE recommends for tiredness in adults,2 weighted towards the ones the evidence says get missed most often.What we test when you’re tired all the timeCore panel — included as standardWhat it’s looking forFull blood countAnaemia, infection, blood disorders. The most commonly ordered test for fatigue, and the right starting point.Ferritin, serum iron & transferrin saturationIron stores, not just haemoglobin. You can be iron deficient with a perfectly normal full blood count. Common in women with heavy periods.Thyroid function — TSH & free T4An under- or over-active thyroid. Free T3 and thyroid antibodies added where the picture suggests it.Vitamin B12 & folateDeficiencies causing fatigue, brain fog, pins and needles and mood change.Vitamin D (25-OH)Deficiency causing tiredness, muscle aches and bone pain — very common at this latitude.Coeliac screen — tTG-IgA with total IgACoeliac disease. NICE lists prolonged fatigue and unexplained iron, B12 or folate deficiency as reasons to test.3 It’s one of the least requested tests in fatigue.1HbA1cDiabetes and pre-diabetes, which often present as tiredness long before anything else.Kidney function (U&E) & eGFRKidney function, and salt and potassium balance — relevant if you’re dizzy or lightheaded.Liver function testsLiver inflammation or fatty liver. Abnormal in around a quarter of fatigue presentations.1Bone profile — calcium, phosphate, ALP, albuminCalcium and bone chemistry, which affect both fatigue and muscle pain.MagnesiumDeficiency causing muscle cramps, twitching, palpitations and fatigue.Inflammatory markers — CRP and plasma viscosityInflammation anywhere in the body. In the 2025 audit, plasma viscosity had the highest abnormality rate of any first-line test.1Creatine kinase (CK)Muscle inflammation or damage — worth having when the aching is muscular. Requested in only 1.4% of fatigue presentations.1Extra tests we may suggestAdded where your symptoms point that wayWhen we’d suggest itLying & standing heart rate and blood pressureIf you go dizzy on standing or your heart races at rest. Measured lying down, then at intervals over ten minutes on your feet. Simple, and the measurement most often not yet done.ECGPalpitations, a racing heart or an irregular pulse. See our ECG & heart rhythm recording page.Female hormones — FSH, LH, oestradiolWhere your cycle has changed or perimenopause is in the frame. We’ll also be straight with you about the limits of hormone blood testing. See women’s health screening.Prolactin, testosterone & SHBGIrregular or absent periods, unwanted hair growth, or suspected PCOS.Morning cortisolWhere the pattern raises a question about adrenal function.Autoimmune screen — ANA, rheumatoid factor, anti-CCPJoint pain with morning stiffness, or a family history of autoimmune disease.Nothing is taken until you’ve agreed to itYou’ll see the list, the reason for each test and the total cost before a single sample is taken. If we don’t think a test will tell us anything useful, we’ll say so — you are not getting sold the biggest panel on the list. Individual tests and other panels are on our blood tests & phlebotomy page and in the full price list.The processFrom the first call to the answerFive steps, and you can stop after any of them.1A free 10-minute call with a GPYou tell a doctor what’s been going on. They tell you what’s worth doing — tests, a longer appointment, something specific to ask your own GP for, or nothing at all. No card details, no obligation, nobody chases you afterwards. Pick a time here.2A 30-minute appointmentThe full history, properly. Everything you’ve already had done and what you were told — including the parts you’ve stopped mentioning because they sound vague. Face-to-face, or by video if getting here is the hard part.3We agree what to test, and what it costsItemised before anything is taken, and you can say no to any of it.4Bloods taken here, reviewed by a doctorTaken at the clinic on Dudhope Street. Routine results in 48–72 hours; specialist panels 5–10 days. Every result is reviewed by a GP before you hear about it.5A conversation, then it in writingA doctor goes through what came back, what it means and what happens next. Then a written record of the whole thing — yours to keep, to reread at 11pm, or to hand to your NHS GP.What it costsPriced before you commit, not afterNo packages you didn’t ask for and no surprises after the fact.

Is there any point?Often, yes — for two reasons. A result inside the reference range can still be low or high for you, and that only becomes clear when someone looks at it alongside your symptoms and your other results. And standard panels don’t include everything; ferritin, coeliac testing and creatine kinase are all recommended for tiredness and all rarely requested.1Bring your previous results to the free call and we’ll tell you honestly whether more testing would add anything. Will you just tell me it’s stress?Stress and exhaustion are real and they cause real physical symptoms, so it may come up. But it isn’t a conclusion we reach by default or before looking. If we do end up there, it’ll be after we’ve ruled out what’s ruleable, and it’ll come with a plan rather than a shrug. Is the free call really free?Yes. Ten minutes with a GP, no card details, no obligation. It isn’t a full consultation, so it can’t include a diagnosis, a prescription or a sick note — ten minutes isn’t long enough to do those properly and we won’t pretend otherwise. It’s there so you can find out what would actually help before you spend anything.If you do go ahead afterwards, nothing is added to your bill for the call. Can I just have the blood tests without the appointment?You can — we offer individual tests and panels on their own, listed on our blood tests & phlebotomy page. But for unexplained tiredness we’d usually advise against it. The value here isn’t the sample; it’s someone taking the history first so the right tests get chosen, and then explaining what comes back. About coming to us Do I have to leave my NHS GP?No. Nothing changes with your NHS practice, and you don’t need to be registered with one to see us. We don’t contact your GP unless you ask us to. Plenty of patients use us for one specific thing and keep everything else where it is. What if you don’t find anything?Then we’ll tell you that clearly, and we’ll tell you what we think is going on and what’s worth trying. Ruling things out has real value. But “your tests are clear” is the start of the conversation here, not the end of it. How long does it take to get results?Routine blood tests come back in 48–72 hours. Specialist panels take 5–10 days. A GP reviews everything before you hear about it, and you get told what it means by a person — not by text and not through a portal. When not to wait for a private appointmentIf you have chest pain, you’re fainting, or you’re breathless at rest, please contact NHS 111 — or 999 if it’s severe. Private testing isn’t the right route for symptoms that need urgent assessment.EvidenceWhy we test what we testThe panel is built against published guidance, not a price list.It’s built around the first-line investigations NICE recommends for an adult presenting with tiredness or fatigue,2 weighted towards the tests the published evidence says get left out.What the research showsIn 2025, researchers audited 16,889 primary care test requests where tiredness or fatigue appeared in the clinical details, and compared them against that guidance.1 Full blood count, kidney function, liver function and thyroid stimulating hormone were requested in around 80–89% of cases. But ferritin was requested in just 9.4%, coeliac testing in 3.2%, and creatine kinase in 1.4%.The abnormality rates ran the other way. Plasma viscosity was abnormal in 37% of cases, ferritin in 26% and liver function tests in 25%. Some of the tests most likely to explain your symptoms are among the least likely to have been done.Coeliac disease is a specific example. NICE guideline NG20 lists prolonged fatigue, and unexplained iron, vitamin B12 or folate deficiency, among the reasons to offer serological testing.3 It remains one of the least requested tests in people presenting with tiredness.1Handjiev S, Nobes J, Murphy MJ. ‘Tired all the time’: what general practitioners request and find in patients with tiredness/fatigue — an audit against NICE clinical knowledge summary of tiredness/fatigue in adults.
