FAQs - Booking your appointment
- Do all tests need a GP appointment?
Most blood tests are taken during a GP appointment, so the £75 GP fee (£67.50 with DocTap Pass) applies. Some tests are the exception: asymptomatic STI tests and certain health screens are taken by a healthcare assistant (HCA), so the GP fee does not apply. STI tests without a GP appointment include: • STI screen: HIV, syphilis, chlamydia and gonorrhoea, from £128 • HIV, from £63 • Chlamydia and gonorrhoea, from £74 • HIV early detect, from £174 • Early detect screen: HIV, hepatitis B and C, chlamydia and gonorrhoea, from £267. Health screens without a GP appointment include: • Bronze health screen: full blood panel, vitals and a same-day report, from £172 • HbA1c diabetes check, from £68 • Iron deficiency screen, from £95. If you have symptoms, or want a doctor to advise, review and treat, choose the GP version instead.
- Do I need a GP referral to book a blood test?
No referral needed. Book a GP appointment and your GP arranges the right tests and takes your sample during the consultation. You can browse our A-Z list to check tests and prices first.
- How do I get a specific blood test I already know I want?
Book a GP appointment and tell the GP what you're after. They'll arrange the test and take your sample during the consultation. You can browse our A-Z list to check tests and prices beforehand, but the test itself is ordered in your appointment.
- How do I prepare for my test?
Most blood tests need no preparation. A few may need you to fast beforehand. If yours does, we'll tell you in advance, in your booking summary and confirmation email, along with any other instructions. The focused blood panel does not require fasting.
- Can you take bloods for my child?
Our laboratory partner TDL operate a Patient Reception at 76 Wimpole Street, London W1G 9RT where they are able to take bloods for children under 16. Your doctor will give you a phlebotomy form during your appointment so you can bring this with you to the patient reception. Our staff are not able to take blood from children under 16 in our clinics.
- Can I walk in for a blood test appointment?
While occasional walk-in slots may be available, we strongly recommend booking online to secure an appointment at a time that suits you.
- Do you offer blood testing at all of your clinic locations?
You can attend any of our clinics for your blood test. Some locations have on-site laboratories for faster results, and you can easily find your nearest clinic and view available services on the DocTap booking page.
FAQ - About our blood tests
- Who takes my blood sample?
All blood samples at DocTap are taken by qualified healthcare professionals - either a GP or Healthcare Assistant (HCA). We follow strict clinical standards to ensure safety, accuracy, and comfort.
- Are your tests UKAS accredited?
Yes. We use UKAS-accredited laboratories for testing ensuring that all results meet the highest standards of quality, accuracy, and reliability.
- Can I request specific blood tests during my appointment?
Yes, you can book an appointment with a GP to discuss the blood tests you need and bring any supporting documentation with you. The GP will review your request, take your sample, and order the tests as clinically appropriate.
- My doctor has requested I have some tests done, can I get these done with you?
If a patient requests blood tests recommended by another doctor, we may be able to help. However, the tests will only be carried out if a DocTap doctor deems them to be clinically appropriate. Please note, we do not offer a standalone 'phlebotomy service' (i.e. blood collection without testing). To proceed, the patient must book a GP consultation and pay the standard fee. During the appointment, the doctor will review the patient's condition and decide whether to carry out the requested tests. Any supporting information from the referring doctor can help our GP make this decision.
- What types of blood tests do you offer?
We offer a range of blood tests and health screens, including checks for infections, liver and kidney function, cholesterol, and other routine markers. Your clinician can recommend the most suitable tests based on your health and risk factors.
- I can't find the test I need on your website, do you offer it?
Our A-Z test list shows the full range of tests we offer and their prices. Some specialist tests can only be carried out by specific providers, so contact us if you're unsure. View the A-Z blood tests list → https://doctap.co.uk/blood-test-prices
FAQ - Results & turnaround times
- Will a doctor explain my results to me?
With the focused blood panel with GP review, a doctor reviews your results with you in the same visit. For other blood tests, your medical report and notes are available in your patient portal, and if a follow-up is needed we'll let you know. A GP review is available as an option.
- How quickly will I get my results?
At our five clinics with on-site labs (Canary Wharf, Hammersmith, Kings Cross & Euston, Liverpool Street & Bank, and London Bridge), key blood results can be ready in the same visit. Most other tests return within 24 to 48 hours, depending on what's ordered.
- Can I access and share my results?
Yes, you can securely access and download a complete copy of your results from your DocTap patient portal, and share them with any healthcare provider if needed.
- What happens if my results need urgent attention?
For tests requiring urgent review, your clinician will prioritise processing and contact you directly if immediate action or treatment is needed.
- I already have blood test results. Can a doctor explain them?
Yes. Book a GP appointment and bring your results and any relevant documents, and a doctor will talk you through them.
FAQ - Focused blood panel with GP review in one visit
- How is this different from a standard GP blood test appointment?
This appointment combines key blood tests with a GP review in the same visit. Your blood sample is taken when you arrive, processed in our on-site lab, and reviewed with your GP before you leave. With a standard GP blood test appointment, your GP arranges any tests you need during the consultation and takes your sample, but the results are usually available afterwards rather than being discussed during the same appointment.
- What is the focused blood panel with GP review?
A single appointment where your blood is taken on arrival, a focused panel is processed in our on-site lab in about 15 minutes, and a GP reviews the results with you in the same visit. You leave with your results explained and a plan. Available at our five clinics with on-site labs.
- Which clinics offer this appointment?
Our five London clinics with on-site labs: Canary Wharf, Hammersmith, Kings Cross & Euston, Liverpool Street & Bank, and London Bridge.
- How long does the appointment take?
Around 30 minutes. Your blood sample is taken when you arrive, your key results are ready in around 15 minutes, and you then meet with your GP to review the results and discuss any next steps.
- Do I need to fast before my blood test?
No. The focused panel does not require fasting. If any test ever needs preparation, we will tell you in your booking summary and confirmation email.
- What if my GP wants tests beyond the panel?
If your GP feels further tests are clinically appropriate, they can arrange them during your appointment. Some additional tests can be processed on-site, while others are sent to our partner laboratory and the results are shared with you afterwards.
FAQ - Prices & insurance
- How much do your tests cost?
Our A-Z test list (https://doctap.co.uk/blood-test-prices) shows the cost of all blood, urine and stool tests that we offer. Individual test prices start from £23. In addition to the cost of tests, there is a £20 handling fee and an appointment fee, starting from £10 for a healthcare assistant or £75 for a GP, during which your sample is taken. For example, a Full Blood Count is £38, a Cholesterol test £41 and a Thyroid (TSH) test £38, before fees. DocTap Pass, a one-off £15 pass, gives 10% off eligible tests and appointment fees for 12 months.
- Are there extra fees on top of the test price?
Yes, and we show them upfront: a £20 handling fee and a £75 GP appointment fee (£67.50 with DocTap Pass). There are no charges beyond the test price, handling fee and appointment fee.
- What is DocTap Pass?
DocTap Pass is a one-off £15 pass that gives you 10% off eligible DocTap appointments and tests for 12 months. Medications and imaging scans are excluded. You can add Pass when you book or when adding eligible tests during your consultation.
- Will my insurance provider cover my blood tests?
You should contact your insurance provider directly to confirm if you are covered under your plan. Your doctor can provisionally add the tests to your DocTap account, which allows you to check with your insurance provider before proceeding.
