Thyroid Function Test: Comprehensive Assessment for Thyroid Health

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 underactive 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.

Thyroid Function Tests (TFTs)

Thyroid function tests assess how well your thyroid gland is working, which plays a key role in regulating metabolism, energy levels, and blood sugar balance. The standard initial tests include TSH (Thyroid Stimulating Hormone) and Free T4, which help identify whether the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism). Thyroid health is particularly important in people with diabetes, as thyroid disorders can contribute to symptoms such as fatigue, weight changes, and unexplained fluctuations in blood glucose levels.

For a more comprehensive assessment, we offer different levels of thyroid profiles depending on your clinical needs:

  • Thyroid Profile 1 (Basic) - £ 75
    • TSH
    • Free T4
  • Thyroid Profile 2 (Comprehensive) - £125
    • TSH
    • Total T4
    • Free T4
    • Free T3
    • Thyroid Peroxidase Antibodies (TPOAb)
    • Thyroglobulin Antibodies (TgAb)
  • Thyroid Profile 3 (Advanced Function) - £95
    • TSH
    • Free T4
    • Free T3

These profiles allow us to not only assess thyroid function but also detect autoimmune thyroid conditions such as Hashimoto’s thyroiditis and Graves’ disease, which are more common in individuals with Type 1 diabetes or persistent metabolic symptoms.

How Many Attempts to Collect the Blood Sample?

  • Please take note of the following in our Phlebotomy policy: Each staff member is permitted only two attempts to collect a blood sample from a patient.
  • However, if a patient's veins are difficult to access, another phlebotomist may take over the collection, or the patient will be rebooked to be attended by our Senior Registered Manager, with the patient's consent.
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 We provide a same-day blood result service for some blood tests (Monday – Friday, excluding Bank Holidays). A £ 35 fee for Phlebotomy + Courier charge will be applied for all Bloods.

Frequently Asked Questions (FAQs)

  1. What is a blood test for thyroid function?
A Thyroid Function Blood Test checks for certain hormones in your blood to see how well your thyroid gland is working. This can help find conditions where the thyroid is either too active or not active enough.
  1. Why is it important for my health to get my thyroid tested?
The thyroid gland controls many body functions, such as metabolism, energy levels, body temperature, heart rate, and more. Thyroid levels that are too high or too low can change your mood, weight, energy, and general health.
  1. How long does it take to get results?
Depending on how long it takes the lab to process the samples, results are usually ready in a few days. Your doctor will explain what the numbers mean for your health.
  1. What do thyroid tests that aren't normal mean?
If your hormone levels are too high or too low, it could mean you have hypothyroidism (an underactive thyroid), hyperthyroidism (an overactive thyroid), or another thyroid disorder. Your doctor will look at the results in light of your symptoms and medical history.
  1. How often should you check your thyroid function?
How often you do it depends on how healthy you are. People who have thyroid problems, take thyroid medication, or have symptoms that are related to thyroid problems may need to be checked on a regular basis. Others may only need to be tested once a year or as directed by a doctor.

When is a Thyroid Ultrasound Recommended?

If your thyroid blood tests show any abnormalities, further imaging may be recommended to assess the structure of the thyroid gland. While blood tests evaluate how your thyroid is functioning, they do not detect physical changes such as nodules, cysts, or enlargement.

A thyroid ultrasound scan provides a detailed view of the thyroid and surrounding structures, helping to identify potential causes of abnormal results, including nodules or inflammation. This is particularly important if you have persistent symptoms, abnormal thyroid levels, or a palpable neck lump.
