Total Thyroid Profile Health Test-5 indicators （in store test）

The Total Thyroid Profile is a 5-marker blood test measuring TSH, free T4, free T3 and two thyroid antibodies for a fuller assessment of thyroid function, processed by London Medical Laboratory (LML), a UKAS-accredited ISO 15189 laboratory, and sold by Ways Pharmacy (UK).

Key facts

Who it is for

• People with thyroid symptoms — fatigue, weight change, mood changes, temperature intolerance — wanting a fuller assessment than TSH and T4 alone
• People being investigated for autoimmune thyroid conditions such as Hashimoto's or Graves' disease, where antibodies are relevant
• People with a family history of thyroid disease wanting comprehensive screening
• People on thyroid medication who want a fuller picture between GP reviews

Not suitable for: people who only want a basic check (the Thyroid Function Test covers TSH and free T4); acutely unwell people who need urgent assessment; replacement for assessment by a doctor.

What is measured

• Thyroid Stimulating Hormone (TSH) — the pituitary hormone that signals the thyroid; the most sensitive first-line marker
• Free T4 (thyroxine) — the main thyroid hormone in its unbound, active form
• Free T3 (triiodothyronine) — the more active thyroid hormone, useful in fuller assessment
• Thyroid Peroxidase Antibodies (TPO) — autoantibodies linked to autoimmune thyroid disease
• Antithyroglobulin Antibodies — a second autoantibody used to investigate autoimmune thyroid conditions

How it works

1. Complete payment online and choose your option: an appointment at Holborn London, or an at-home self-collection kit posted to you.
2. For in-store, attend Ways Pharmacy, 77 Southampton Row, London WC1B 4ET, where a trained operator takes one tube of venous blood. For at-home, follow the kit instructions to collect a finger-prick sample and return it in the prepaid packaging.
3. Your sample is sent to London Medical Laboratory for analysis.
4. You receive a written report with each marker against its reference range; values outside the range are flagged, typically within 3–5 working days.
5. A pharmacist can talk you through the result and, where appropriate, recommend GP follow-up.

Frequently asked questions

Do I need to fast before this test?

No. A thyroid profile does not require fasting, so you can eat and drink as normal. If you take thyroid medication, ask the pharmacist about timing, as it can affect the reading; otherwise take your usual medicines unless your GP has advised otherwise.

What do the thyroid antibodies tell me?

Thyroid peroxidase and antithyroglobulin antibodies help investigate autoimmune thyroid conditions, where the immune system targets the thyroid. Their presence is interpreted alongside TSH, free T4 and free T3 and your symptoms — they are one part of the picture, not a diagnosis on their own.

How long do results take?

Results are typically returned 3 to 5 working days after London Medical Laboratory receives your sample. You will receive a written report showing each marker against its reference range, with out-of-range values flagged.

Is the laboratory accredited?

Yes. Samples are processed by London Medical Laboratory (LML), a UKAS-accredited laboratory operating to ISO 15189, the international standard for medical testing laboratories.

What if a result is abnormal?

An out-of-range result does not diagnose a condition on its own. The pharmacist will explain what it means and recommend GP follow-up where appropriate, which may include repeat testing. Reference ranges are provided with your report.

When to seek further advice

This profile does not diagnose a thyroid condition. Reference ranges are provided with your report; discuss your results with a clinician, and if a result is abnormal, follow it up with your GP. Seek prompt medical advice if you feel acutely unwell.

This is a private health screening service. Results are interpretive and do not replace clinical diagnosis by a GP or specialist. Abnormal results should be followed up with your GP.
