How It Works

Book a Private Blood Test
Online. Today.

No GP referral. No waiting list. No awkward conversation. Choose your panel, book a clinic near you or arrange at-home phlebotomy, and get your results in 48 hours. Private blood testing with TrueVitals takes four steps and about 15 minutes of your time. Here is exactly how it works.

Four Steps

From booking to results in 48 hours

1

Choose your panel

Browse the TrueVitals panels and choose the level of depth that matches your goals. Not sure which to pick? The health quiz takes 3 minutes and recommends a panel based on your symptoms, lifestyle, and health history.

Advanced (74 markers, £269) — core blood health, liver, kidney, thyroid, lipids, vitamins, iron, and metabolic markers. A strong starting point for general screening.

Ultimate (114 markers, £349) — everything in Essential plus full hormonal profile, advanced lipids (ApoB, Lp(a)), fasting insulin, HOMA-IR, immunoglobulins, tumour markers, and coeliac screening. The most popular choice and the most comprehensive private blood test under £400 in the UK.

Signature (200+ markers, £799) — the deepest blood test available in the UK. 200+ biomarkers via Randox laboratories. Extended autoimmune, allergy, and research markers alongside everything in Ultimate. Available at Randox clinic locations.

Book your appointment

Choose how and where you want your blood drawn:

Clinic phlebotomy (+£19) — attend one of 103+ clinic locations across the UK. Walk in, have your blood drawn by a qualified phlebotomist, walk out. Most appointments are available within days. Find your nearest clinic.

At-home phlebotomy (+£39) — a mobile phlebotomist comes to your home, office, or any private location. Same professional venous blood draw, same accredited laboratory processing, complete privacy. Morning appointments available for fasting tests.

Both options use venous blood draws (not finger-prick). Venous draws produce larger, higher-quality samples that allow 100+ markers to be tested from a single collection. Finger-prick kits limit you to 10 to 20 markers and have higher failure rates.

3

Attend your 15-minute appointment

The phlebotomist draws a small amount of blood from a vein in your arm. It's the same procedure used in NHS hospitals. The entire draw takes 5 to 10 minutes. With check-in and labelling, expect 10 to 15 minutes total.

If you're nervous about needles, tell your phlebotomist. They handle anxious patients daily and can make the process significantly more comfortable. Look away, breathe slowly, and it's over before you know it. Most people say the anticipation was worse than the experience.

Your samples are labelled, packaged, and sent to a UKAS-accredited laboratory for analysis. The same laboratory standards and accreditations used by NHS hospitals apply to private blood testing.

Get your results (typically 48 hours)

Your results arrive via a secure online dashboard. No phoning the surgery. No waiting for a callback. No "the doctor hasn't reviewed them yet." You log in and everything is there.

The TrueVitals report goes significantly beyond a list of numbers. Every result is flagged against both standard reference ranges and evidence-based optimal ranges. The AI cross-system analysis identifies patterns between markers across different body systems. Specific, actionable recommendations (supplement forms, doses, dietary adjustments, lifestyle changes) are provided based on your actual data. A medical professional reviews every report before it's released.

Before Your Appointment

How to prepare for your blood test

Fasting: 10 to 12 hours before (overnight)

For panels that include fasting glucose, fasting insulin, HOMA-IR, and lipids, an overnight fast produces the most accurate results. Stop eating at 10pm, attend a morning appointment, and eat normally afterwards. Drink water freely throughout the fast. Coffee, tea, juice, and milk count as breaking the fast. If fasting is not possible, most markers (thyroid, hormones, vitamins, FBC, liver, kidney) are unaffected. Only glucose, insulin, and triglycerides shift meaningfully with food intake.

Hydration: drink plenty of water

Good hydration makes your veins easier to find and the draw smoother. Drink 2 to 3 glasses of water in the hours before your appointment. Dehydrated veins are harder to access and increase the chance of bruising or needing a second attempt.

Timing: morning is best

Cortisol is highest in the morning (the cortisol awakening response). Testosterone peaks in the early morning. Fasting is easiest overnight. For the most consistent, interpretable results, book a morning appointment between 7am and 10am. If only afternoon slots are available, the results are still valid for most markers — the report accounts for collection time.

Medications: take as normal (with one exception)

Continue all regular medications unless specifically advised otherwise. The exception: if you take biotin (vitamin B7) supplements, stop them 48 to 72 hours before your test. High-dose biotin interferes with immunoassay-based tests and can produce falsely normal or falsely abnormal results for thyroid, hormones, and some cardiac markers.

Exercise: avoid strenuous training for 24 hours

Intense exercise temporarily elevates CK, AST, cortisol, and inflammatory markers. For the most accurate metabolic and liver readings, avoid heavy training in the 24 hours before your appointment. Light walking and normal activity are fine.

After Your Results

What to do once you have your report

If everything is normal: that's the best possible outcome. You have a comprehensive baseline. Save it. Retest in 12 months to track trends. The longitudinal comparison between tests is where the deepest insights emerge. How often to retest.

If specific markers are flagged: the report explains what each finding means, how it connects to other markers, and what to do about it. Recommendations include specific supplement forms and doses, dietary adjustments, and lifestyle changes. For findings that need clinical attention, the report recommends discussing with your GP and provides the context your GP needs to act.

Taking results to your GP: print or save the report PDF. Book a GP appointment. Highlight the specific findings you want to discuss. Most GPs appreciate the data and many report significantly more productive consultations when patients arrive with comprehensive blood work rather than vague symptoms. Your GP may repeat specific tests through the NHS before prescribing treatment. Will my GP accept private results?

No referral. No waiting list. 103+ clinic locations or at-home phlebotomy. Results in 48 hours. AI-powered report with medical review. Payl8r, Klarna, and Clearpay available.

Concerns Addressed

Things people worry about (and shouldn't)

"I'm scared of needles"

Completely normal. Tell your phlebotomist before they start. They can use smaller gauge needles, apply a numbing spray if available, and talk you through the process. Look away. Breathe slowly. The actual draw takes under 60 seconds. Most people say "is that it?" when it's over. If your anxiety is severe, at-home phlebotomy in a comfortable environment (your sofa, your kitchen) is often significantly easier than a clinical setting.

"What if my results are bad?"

Better to know than not to know. Most abnormal findings are correctable with supplements, dietary changes, or medication. The people who suffer worst from health problems are the ones who discover them late. Finding elevated fasting insulin at 40 and changing your diet is dramatically better than finding out you have type 2 diabetes at 55. The test doesn't create problems. It reveals them while they're still manageable.

"Is private testing as reliable as NHS?"

Yes. Private blood tests are processed by UKAS-accredited laboratories that meet the same ISO 15189 standards as NHS hospital labs. Many providers use the same laboratories. The blood collection method (venous draw by a qualified phlebotomist) is identical. The difference is in which markers are tested, how quickly results return, and the depth of interpretation provided. The laboratory science is the same.

"Can I do this if I'm already under a GP or specialist?"

Yes. Private testing complements NHS care. It does not replace it. Many people use comprehensive private testing to fill the gaps between NHS appointments or to bring more data to specialist consultations. If your consultant has requested specific tests, check whether the private panel covers them to avoid unnecessary duplication.

Common Questions

Frequently asked questions

How do I book a private blood test online?
Choose your panel on the TrueVitals website, select clinic or at-home phlebotomy, complete payment, and book your appointment. No referral needed. The entire booking process takes 5 minutes. View panels and book.
Do I need a GP referral?
No. Private blood testing does not require a referral, prescription, or prior appointment. You choose which tests you want and book directly. Results are sent to you, not your GP. You can share them with your GP if you wish.
Do I need to fast?
For comprehensive panels, a 10 to 12 hour overnight fast is recommended. Drink water normally. Avoid food, coffee, and juice. Book a morning appointment. If fasting isn't possible, most markers are unaffected — only glucose, insulin, and triglycerides change significantly.
How long does the appointment take?
10 to 15 minutes total. The blood draw itself is 5 to 10 minutes. Same procedure as an NHS blood test: venous draw from a vein in your arm by a qualified phlebotomist.
How quickly do results come back?
TrueVitals results are typically available within 48 hours via a secure online dashboard. NHS results typically take 1 to 3 weeks plus a separate GP appointment to discuss them. See what the report looks like.
