Understanding Blood Test Results in the UK

If you've recently had a blood test, you're probably wondering, how long do blood test results take? Waiting for results can be nerve-wracking, especially if you're unsure of what to expect. This guide explains how long different types of blood tests take, when to expect a call from your doctor, and what to do if your results are delayed.

How Long Does a Blood Test Take for Results?

Routine and Specialised Blood Tests

Most routine blood tests in the UK take about 72 hours (3 days) to be processed and reviewed by your GP. If your results are normal, you may not be contacted. However, if your doctor needs to discuss something, they will get in touch.

Test Type Time for Results
 Routine Blood Tests  72 hoursn
 Diabetes (Hba1c)  1 week
 Rheumatoid Arthritis  1 week
 Coeliac Disease (Endomysial Antibody)  2 weeks
 Vitamin D Levels  3 weeks
 Bone Profile Blood Test  1 week
 Liver Function Test  1 week
 Kidney Function Test  1 week
 Thyroid Function Test  1 week
 Full Blood Count (FBC)  72 hours

If your doctor has asked for additional tests, it may take longer to receive a full analysis.

Where Can You Get Your Blood Test Results?

You can access your blood test results in a few different ways:

  1. NHS App – The fastest way to check your results online.
  2. GP Online Services – Log in via your GP practice's website.
  3. Phone Call to Your GP Surgery – If you're unable to access your results online, you can call to ask.
  4. In-person Appointment – If your doctor needs to discuss your results in detail, you may be asked to book an appointment.

Translate My Blood Test Results

Interpreting your blood test results can sometimes be confusing. If you're unsure what your results mean, consider the following options:

  • Ask your GP or Nurse – They can provide a clear explanation based on your medical history.
  • Use the NHS Website – The NHS blood test guide offers insights into common blood tests.
  • Online Blood Test Translators – Some medical websites offer tools to help interpret your results, but always confirm with your doctor.
  • Book a Private Consultation – If you need more detailed guidance, our private blood test services provide expert consultations.

What Happens If You Need a Repeat Test?

If your doctor asks for a repeat blood test, it’s usually because:

  • Your first result was borderline or unclear, and they need to check again.
  • Your result was abnormal, but further tests are needed for confirmation.
  • They need to monitor a condition over time.

Don’t panic—if there’s an urgent issue, your doctor will explain what happens next.

FAQs About How Long Do Blood Test Results Take

How Quickly Will a Doctor Call With Blood Test Results?

Yes, you can view your blood test results on the NHS App or through your GP’s online services.

Some tests, like Vitamin D and Coeliac Disease tests, take longer due to complex processing. If it's delayed beyond the normal timeframe, check with your GP surgery.

What if I don’t get a call about my results?

If you haven’t heard from your doctor and are concerned, check online or call your GP practice to follow up.
