The Thyroid gland plays a crucial role in regulating your metabolism, energy, and overall physical and cognitive health. Our Advanced Thyroid Test measures the levels of thyroid hormones (TSH, FT4, FT3) and detects antibodies; the key biomarkers of autoimmune thyroid disorder.

If you are experiencing unexplained weight changes, fatigue, depression, or hair problems, you must get your thyroid level tested. The private thyroid test by The National Blood Test Clinic UK evaluates T3, T4, and TSH levels to assess how well thyroid function can be regulated.

Why Get Tested

Thyroid disorders are common, especially in women, but they can develop in men too, and are often hard to diagnose due to overlapping symptoms with other conditions. 

An underactive thyroid (Hypothyroidism) may lead to tiredness, weight gain, hair loss, depression, and cold sensitivity. On the other hand, an overactive thyroid (Hyperthyroidism) can result in unexplained weight loss, anxiety, mood swings, trouble sleeping, heat sensitivity, muscle weakness, itchiness, and frequent urination.

If you're experiencing any of these symptoms, our private thyroid test can help you gain clarity. This thyroid test kit is designed to perform convenient at-home testing to check your thyroid levels, including T3, T4, and TSH.

Frequently Asked Questions (FAQs)

What’s the difference between a basic and advanced thyroid test?

A basic test usually checks TSH only. Our advanced test includes FT3, FT4, and
thyroid antibodies — giving a complete picture of your thyroid and immune
activity.

Can thyroid issues affect mental health?

Yes. Imbalances can lead to anxiety, depression, or brain fog.

When should I take the test?

Anytime, but morning samples are ideal. You can test even while on medication just let us know during registration.

Do I need to fast?

No fasting is required for this test.

What does the thyroid function test determine?

Thyroid function tests measure the levels of Triiodothyronine (T3), Thyroxine (T4), and Thyroid Stimulating Hormone (TSH) in the blood. Typically, TSH is tested first, as it regulates the production of T3 and T4, and helps assess how well your thyroid is functioning.

What are the common causes of thyroid disorders in females?

Thyroid disorders in females are often caused by a combination of factors, with genetics and hormonal imbalances being the most common. Autoimmune conditions can also contribute to thyroid dysfunction.

Can thyroid hormone levels be measured at home?

Yes, thyroid hormone levels can be measured at home using a simple finger-prick blood sample. Home thyroid test kits accurately assess hormone levels and can also detect thyroid antibodies, providing valuable insight into your thyroid health.
