The thyroid is a small gland with an outsized influence on how you feel every day. It regulates your metabolism, energy levels, body temperature, mood, weight, and much more. When it is not working as it should, the effects can be far-reaching — and yet thyroid dysfunction is frequently missed or dismissed because its symptoms are so easily attributed to stress, ageing, or simply being busy.
If you have been struggling with unexplained fatigue, unexpected weight changes, persistent low mood, brain fog, or feeling cold when others are comfortable, a private Thyroid Function Test can tell you clearly whether your thyroid is the cause. No guessing. No waiting months for a GP referral.
At Trupoint Health, we offer a comprehensive private thyroid blood test that goes beyond the basic NHS TSH-only screen. Our panel includes TSH, Free T4, and Free T3, giving a clinically complete picture of how your thyroid is actually functioning. Our qualified phlebotomists serve clients across Gloucestershire and the surrounding areas, with results returned securely within 24–48 hours.

What Does the Thyroid Function Test Include?
Our private Thyroid Function Test measures four key markers that together provide a thorough and clinically meaningful assessment of thyroid health — including markers that a standard NHS screen may not routinely include.
TSH — Thyroid Stimulating Hormone
TSH is produced by the pituitary gland and acts as the primary control signal for thyroid activity. A raised TSH indicates that the pituitary is working harder than it should to stimulate the thyroid — a classic sign of an underactive thyroid (hypothyroidism). A suppressed TSH suggests the thyroid is overproducing hormones — consistent with an overactive thyroid (hyperthyroidism). TSH alone, however, does not always tell the full story, which is why we include the markers below.
Free T4 — Thyroxine
T4 is the main hormone produced and secreted directly by the thyroid gland. “Free” T4 refers to the portion that is unbound and biologically active. It regulates metabolism, energy production, body temperature, and heart rate. Low Free T4 alongside a raised TSH confirms hypothyroidism; elevated Free T4 with a suppressed TSH confirms hyperthyroidism. Together, TSH and Free T4 form the core of any complete thyroid assessment.
Free T3 — Triiodothyronine
T3 is the most potent and metabolically active form of thyroid hormone. Some people experience persistent symptoms of thyroid dysfunction despite TSH and T4 results appearing within normal range. Measuring Free T3 captures this picture more completely and is particularly relevant for those already on thyroid medication who feel their treatment is not fully effective.
Thyroid Antibodies — TPO and TgAb (available as an add-on)
Thyroid Peroxidase antibodies (TPO) and Thyroglobulin antibodies (TgAb) are markers of autoimmune thyroid conditions. Elevated TPO antibodies are strongly associated with Hashimoto’s thyroiditis — the most common cause of hypothyroidism in the UK. Elevated TgAb can indicate Graves’ disease or Hashimoto’s. If you have a family history of autoimmune conditions, adding antibody testing provides a significantly more complete picture.
All tests are carried out by our qualified phlebotomists and analysed by accredited laboratories.
Who Should Consider a Thyroid Function Test?
Thyroid disorders are remarkably common — hypothyroidism alone affects an estimated one in twenty women in the UK — and yet they are regularly underdiagnosed. You do not need to be severely unwell to benefit from a thyroid test; the earlier thyroid dysfunction is identified, the easier it is to manage.
This test is particularly well suited to anyone experiencing unexplained fatigue that does not improve with rest, persistent brain fog or difficulty concentrating, changes in weight that are not explained by changes in diet or activity, or a low mood that does not lift. Many people describe feeling cold all the time, noticing hair thinning or loss, or experiencing dry, rough skin — these are all classic signs of a thyroid that is underperforming.
Women over 35 are at statistically higher risk of thyroid dysfunction than the general population, and that risk increases further around the perimenopause and menopause. However, thyroid disorders affect men too, and are frequently overlooked in male patients. Anyone with a close family member who has a thyroid condition or an autoimmune disease should also consider regular testing.
If you are already taking thyroid medication but still not feeling well, this panel — ideally including Free T3 — can help clarify whether your current dose is genuinely optimising your levels.
What to Expect at Your Appointment
Your appointment will typically take no more than 15 minutes from arrival to leaving. Our phlebotomist will confirm your details and take a small blood sample — usually from a vein in the crease of your elbow. Most clients find the procedure causes only mild, brief discomfort.
Timing matters for thyroid testing. We recommend booking a morning appointment, ideally before 10am, as TSH levels are naturally at their highest in the morning. If you take thyroid medication such as levothyroxine, please take your blood test before your morning dose on the day of your appointment.
No fasting is required for the thyroid panel. Results are delivered securely to your personal online portal within 24–48 hours, with each marker clearly explained against standard reference ranges. If any result falls outside the normal range, we recommend discussing it with your GP or an endocrinologist for further guidance.
Why Choose Trupoint Health for Your Thyroid Function Test?
Trupoint Health offers something the standard NHS thyroid screen often does not: a genuinely comprehensive panel that includes Free T3 alongside TSH and Free T4. Many patients find that their concerns are dismissed after a normal TSH result, when in fact a fuller picture would reveal more. We believe you deserve a thorough assessment, not a single data point.
There is no GP referral required. You book directly online, choose a time that works for you, and attend a comfortable, professional appointment with one of our qualified phlebotomists. Every sample is sent to an accredited laboratory for analysis, and results are returned to your secure portal within 24–48 hours. Our pricing is completely transparent — the figure you see at the point of booking is all you pay.

Thyroid Function Test — Frequently Asked Questions
Do I need a GP referral for a private Thyroid Function Test?
No GP referral is required. You can book your Thyroid Function Test directly with Trupoint Health online, at a time that suits you. This is particularly valuable if your GP has declined to test beyond TSH, or if you are experiencing symptoms but have been told your previous results were “normal”.
How quickly will I receive my thyroid test results?
Results are typically available within 24–48 hours of your appointment, delivered securely to your personal online portal. Each marker — TSH, Free T4, Free T3, and antibodies if included — is presented alongside standard reference ranges and a clear explanation of what each figure means.
Do I need to fast before my Thyroid Function Test?
Fasting is not required for the thyroid panel. However, we strongly recommend booking a morning appointment, ideally before 10am, as TSH levels are naturally at their highest in the morning. If you are on thyroid medication, please take your test before your morning dose to ensure the most accurate readings.
How much does a private Thyroid Function Test cost?
Trupoint Health provides transparent, fixed pricing with no hidden fees. Please visit our booking page for current panel prices. Thyroid antibody testing is available as an add-on if you would like a more detailed autoimmune picture.
What happens if my results show something abnormal?
Any result outside the standard reference range will be clearly highlighted within your online results portal, with a plain-language explanation. We recommend sharing out-of-range results with your GP, who can advise on further investigation or treatment. Our team is also happy to help you understand what your results mean.
Is my thyroid test information kept confidential?
Yes, completely. Trupoint Health is fully compliant with UK GDPR and registered with the ICO. Your personal and health data is stored securely and never shared with third parties without your explicit consent. Your GP will only be informed of your results if you choose to share them.
What is the difference between TSH, T4, and T3?
TSH is the pituitary’s signal to the thyroid. T4 is the main hormone the thyroid produces, and T3 is the active form that cells actually use. Measuring all three gives a complete picture — some people show a normal TSH but have poor T4 to T3 conversion that explains ongoing symptoms. Testing T3 can reveal what a TSH-only screen would miss.
Can thyroid problems cause anxiety or depression?
Yes. An overactive thyroid is commonly associated with anxiety and palpitations, while an underactive thyroid frequently presents with low mood and depression. Both conditions can be mistaken for primary mental health disorders. If you are experiencing mood changes alongside physical symptoms such as weight fluctuation or fatigue, thyroid testing is a sensible and often illuminating step.
