Thyroid Panel Blood Test (TSH, FT3, FT4)

Biomarkers/Parameters Included in this Thyroid Function/Panel blood test kit:

• Thyroid-Stimulating Hormone (TSH)

• Free T4 (FT4)

• Free T3 (FT3)

This test can give you an insight into your thyroid health and function. Simply collect a sample of blood at home using a finger prick and send the provided tube to our lab for analysis. You will get a lab test report from our lab within 1-3 days of sample receipt.

Thyroid disorders can cause weight fluctuations, sleep difficulties and sensitivity to heat or cold. Parameters tested are:

1. Thyroid Stimulating Hormone (TSH): TSH is a hormone produced by the pituitary gland in the brain. Increased levels of TSH can be related to primary hypothyroidism (thyroid dysfunction). Decreased levels of TSH can be related to secondary hypothyroidism (pituitary or hypothalamus dysfunction). 
2.  Free T4: Free thyroxine (FT4) is a thyroid hormone produced by the thyroid gland. It plays a crucial role in regulating metabolism and energy levels in the body. Free T4 refers to the portion of T4 that is not bound to proteins in the blood and is available for use by cells. Increased levels of free T4 (FT4) may be an indicator of hypothyroid states, pituitary insufficiency or iodine insufficiency. 
3. Free T3: Free triiodothyronine (T3) is another thyroid hormone that plays a key role in regulating metabolism, growth, and energy production. Like free T4, free T3 refers to the unbound, active form of T3 that is available for cellular use. Free T3 levels provide insight into thyroid function and metabolism.

Thyroid Blood Test FAQs:

Q1: What is included in a Thyroid Profile test?
A: This test measures TSH (Thyroid Stimulating Hormone), Free T4 (Thyroxine), and Free T3 (Triiodothyronine). It provides a comprehensive overview of thyroid function, helping detect underactive (hypothyroidism) or overactive (hyperthyroidism) thyroid conditions.

Q2: How often should I test my thyroid?
A: NICE and NHS guidance recommends testing:

• At diagnosis of thyroid disease

• 6–12 weeks after starting or adjusting treatment

• Periodic monitoring as advised by your GP
  This test can help track changes between GP appointments, but results should always be interpreted by a healthcare professional.

Q3: Can this test replace NHS testing?
A: No. This test is supplementary. Results should always be reviewed with a GP or healthcare professional, particularly if you are taking medication or have abnormal results. NHS appointments remain essential for diagnosis and treatment planning.

Q4: How do I provide a sample for this test?
A: This test requires a finger-prick blood sample. The kit includes detailed instructions, collection tubes, and a prepaid envelope for lab submission. Most users find the process quick and straightforward.

Q5: Is this test safe?
A: Yes. This test is safe, minimally invasive, and processed in UK-accredited laboratories. It is designed for convenient and hygienic sample collection.

Q6: How long does it take to get results?
A: Once your sample reaches our lab, results from this test are typically available within 2–5 working days. You receive a secure online report showing TSH, Free T4, and Free T3 levels, along with reference ranges to discuss with your GP.

Q7: What do my thyroid test results mean?
A: This test report shows:

• TSH – regulates thyroid activity

• Free T4 – main thyroid hormone

• Free T3 – active thyroid hormone, measured especially for hyperthyroidism
  A GP can interpret results in context, adjust medication if necessary, and recommend further monitoring.

Q8: Can I take this test if I am on thyroid medication?
A: Yes. This test is particularly useful for people taking medication such as levothyroxine or carbimazole, helping monitor treatment effectiveness. Always share results with your GP before any medication adjustments.

Q9: Do I need a GP referral to take this test?
A: No referral is required. You can order this test directly, but abnormal results should always be discussed with your GP.

Q10: Is this test suitable for all ages?
A: This test is suitable for adults of all ages. Children or pregnant women should consult a healthcare professional before testing.

Q11: How accurate is this test?
A: This test is processed in UK-accredited laboratories using clinical-grade analyzers, providing accuracy comparable to NHS laboratory tests.

Q12: Can I monitor my thyroid long-term with this test?
A: Yes. Many users monitor their thyroid every 3–6 months or as advised by their GP to track medication response and hormone trends. The secure online results make it easy to compare previous tests.

Q13: What if my results are abnormal?
A: Do not adjust medication on your own. Contact your GP with your results for interpretation, further testing if needed, and treatment advice.

Q14: How does this test compare to NHS testing?
A: This test measures the same markers as standard NHS blood tests but offers more convenience and faster access. It allows you to monitor thyroid function between GP visits.

Q15: Can I use this test to track lifestyle effects on thyroid health?
A: Yes. Results can support discussions with your GP about diet, exercise, or stress management, which may influence thyroid function.
