A thyroid function test or TFT blood test looks at the levels of thyroid stimulating hormone (TSH) and thyroxine (T4) in your blood. It can be used to detect an under-active thyroid or over-active thyroid gland.
A thyroid function test is an important component of our unwell patient screen. Do not worry about determining for yourself which if any blood test you need. This is something that your doctor will be able to determine and explain during your consultation.
All our blood tests are available same day with some of the fastest results in London. One of our doctors will take the time to explain to you what your test results mean and put in place any appropriate next steps based on those results.

This is only a small sample of the many blood tests which DocTap provide. Our expert doctors can advise you during your consultation on the most appropriate tests for your condition. View all blood tests.
DocTap seek to provide the most convenient, fastest, effective and best value private blood testing service in London. With 12 blood test centres across London and same day appointments available 7 days a week, it has never been easier to book a tft blood test. We are proud to partner with The Doctors Laboratory (TDL) which has a worldwide reputation for excellence.
Unlike many blood test clinics, you will see a UK accredited GP who will be able to offer their expert option on what test is most appropriate for you. Your results will also be accompanied by a written analysis of what they mean and what your doctor advises you to do next. Should additional treatment be required, or if you simply wish to discuss the results in more detail, then you can book a 15 minute follow up consultation for only £25. This can either be at any DocTap clinic or over the phone. When booking your follow up consultation you can request to see you original doctor if you wish (subject to their availability).
Should you require a full consulation before deciding to have a tft blood test then there may be insufficient time to also take a blood sample in the appointment. In that case you can choose to either go to our walk in laboratory by Oxford Street (£15 phlebotomy fee applies) or to make a second appointment for the doctor to take the bloods.
The thyroid gland is found at the front of the neck and is a small gland with a big job. The chemicals (called hormones) that it makes and releases are essential for the smooth running of the entire body. When there is a problem and too much or too little hormone is released then there can be an array of different symptoms. The thyroid gland is also connected to the pituitary gland in the brain. The pituitary can sense when too much or too little thyroid hormone is being produced and signals to the thyroid to restore the balance.
If the level of thyroxine becomes too low, this is known as hypothyroidism. This can make you feel tired or cold, gain weight, lose hair or lead to depression. These are common symptoms that can be caused by a range of health problems, often no cause can be found, so it is important that your thyroid gland function is tested with a simple blood test to ensure that an under-active thyroid isn't missed.
If the level of thyroxine is too high, this is known as hyperthyroidism. This can lead to weight loss, heat intolerance, palpitations and eye problems.
There are many reasons why the thyroid can become disrupted. The most common are autoimmune conditions - which is where the body wrongly attacks itself. The immune system stops recognising the thyroid as part of the body and sees it as a foreign invader.
Both under-active and overactive thyroid conditions can be treated, either with medication or sometimes with other treatments such as surgery. The blood tests are also used to monitor the response to treatment and ensure that the medication is dosed at the correct levels.See a GP for a TFT blood test now
I was seen on time by a very good GP and the consultation was not rushed in way. All good.Sunday, March 24, 2019
The whole process and quality of care by the doctor was excellent.Friday, March 22, 2019
My doctor was really nice, very clear and very patient. I would definitely go back if I need help.Friday, March 22, 2019
Doctor was amazing, location was easily accessible and got updated when my doctor was running later. However pricing is not very clear... paid £30 for appointment and then money for results on same day. I assumed £30 was a deposit that I could use towards results cost (which it was not) so website should be clearer on this as it is a little misleading as other places provide same service but cheaper!Friday, March 22, 2019

It was a bit difficult figuring out where it was on the premises but that could have been because of how sick I was and from being out of town. The doctor was amazing.Monday, March 11, 2019
Excellent doctor. Great personality.Saturday, March 9, 2019
Doctap is great. I had several questions before my appointment which the team who replied to my emails (Fouzia and Christof), dealt with really quickly, within 2 minutes of me emailing. This meant I knew exactly what I was getting from my appointment and understood the costs and timing of the blood tests. I've been treated by lots of fertility clinics in UK and overseas, and they have terribly slow customer service, I was beginning to think it was the whole medical industry, but you are a refreshing exception. If you were to bring this customer service excellence to fertility treatment, there might actually be some hopeful parents who don't end up feeling like they've been taken for a massive ride by a bunch of lack lustre health professionals who make continual errors, and fail to respond to enquiries.Friday, March 8, 2019
