Waiting for blood test results can feel stressful, especially if you’re not sure what to expect. At OneMedicine, we’re often asked: how long do blood test results take? The answer depends on the type of test, how it’s processed, and whether your doctor needs to review the results in more detail.
This guide explains typical timelines, how to access your results, and when to expect a call from your GP.
How Long Does a Blood Test Take for Results?
Most routine blood tests in the UK are ready within 72 hours (3 days). If your results are normal, you may not hear from your NHS GP. However, if something needs to be discussed, you’ll usually be contacted directly.
At OneMedicine in Edgbaston, we offer rapid turnaround on many blood tests, with some results back within just 24 hours, so you don’t have to wait unnecessarily. If you’re wondering how long does a blood test result take, the table below gives a clear breakdown.
| Test Type | Typical NHS Time for Results |
|---|---|
| Routine Blood Tests | 72 hours |
| Full Blood Count (FBC) | 72 hours |
| Diabetes (HbA1c) | 1 week |
| Rheumatoid Arthritis | 1 week |
| Thyroid Function Test | 1 week |
| Kidney Function Test | 1 week |
| Liver Function Test | 1 week |
| Bone Profile | 1 week |
| Coeliac Disease (Endomysial Antibody) | 2 weeks |
| Vitamin D Levels | Up to 3 weeks |
If your doctor has requested additional or specialised tests, full analysis can take longer. This explains why answers to how long does it take for blood test result can vary so much.
Where Can You Get Your Blood Test Results?
You can usually access results in these ways:
✔ NHS App – the fastest option for NHS patients
✔ GP Online Services – log in via your surgery’s website
✔ Phone Call – if you prefer, you can call your GP practice
✔ Face-to-Face Appointment – if your results need careful discussion
At OneMedicine, we simplify this: your results are securely shared with you, and we will go through them in detail, so you always leave with clarity and a plan.
Making Sense of Your Results
Blood test reports can be full of numbers and abbreviations that aren’t always easy to interpret. To avoid confusion:
- Ask your GP or nurse – they can explain results in the context of your health.
- NHS Website – a useful reference for common tests.
- Private Consultation – at OneMedicine, we explain results in plain language and recommend next steps, so you don’t have to search for answers online.
What Happens If You Need a Repeat Test?
Sometimes your doctor may ask for a repeat test. Common reasons include:
- Results were borderline or unclear
- An abnormal result needs confirmation
- Your condition requires ongoing monitoring
Don’t panic—a repeat test doesn’t always mean something serious. If there’s an urgent issue, you’ll be contacted quickly.
Reduced Risk of Bruising
A common concern after a blood test is bruising around the puncture site. This usually happens when the vein is missed, or the needle is not inserted smoothly. At OneMedicine, all blood tests are carried out by experienced doctors, not rushed phlebotomists, which greatly reduces the risk of bruising or discomfort.
Our doctors take time to locate the right vein, use the correct technique, and ensure the process is as comfortable as possible. This not only improves your experience on the day but also means you can leave the clinic without worrying about visible marks on your arm.
FAQs: How Long Do Blood Test Results Take?
How quickly will my NHS doctor call?
If urgent, you’ll usually hear within 24–48 hours. Otherwise, results are often only discussed if follow-up is needed.
Why are my NHS results delayed?
Specialised tests like Vitamin D or Coeliac screening take longer due to more complex lab processing.
Can I check my results online?
Yes – NHS patients can use the NHS App. At OneMedicine, results are shared directly with you, often the next day.
What if I don’t get a call?
If you’re worried, contact your GP or, if tested with us, your OneMedicine doctor will review and follow up proactively.
