Overview of the Thyroid Full Profile Test
The Thyroid Full Profile is a comprehensive six-marker blood test assessing thyroid hormone production, thyroid regulation and two important thyroid autoantibodies.
The profile measures T4, Thyroid-Stimulating Hormone (TSH), Free T3, Free T4, Thyroglobulin Antibodies and Thyroid Peroxidase Antibodies.
Thyroid hormones influence metabolism, energy use, temperature regulation, heart rate and many other physiological processes.
TSH provides information about how the pituitary gland is signalling the thyroid, while Free T3 and Free T4 assess circulating thyroid hormones available to tissues.
The antibody component adds information about possible autoimmune thyroid activity.
This makes the Thyroid Full Profile broader than a basic TSH-only or TSH/Free T4 test. The Thyroid Full Profile costs £149.
What Does the Thyroid Full Profile Test Check?
The Thyroid Full Profile combines thyroid hormones, pituitary regulation and thyroid autoantibodies. This test measures 6 biomarkers.
T4
Measures total Thyroxine circulating in the blood, including both protein-bound and free hormone.
Thyroid-Stimulating Hormone (TSH)
Measures the pituitary hormone responsible for regulating thyroid hormone production.
Free T3
Measures the free circulating fraction of Tri-iodothyronine, the more biologically active thyroid hormone.
Free T4
Measures the free circulating fraction of Thyroxine available to body tissues.
Thyroglobulin Antibodies
Detects antibodies directed against Thyroglobulin, which can be associated with autoimmune thyroid conditions.
Thyroid Peroxidase Antibodies
Detects antibodies directed against Thyroid Peroxidase, an enzyme involved in thyroid hormone production.
Who May Benefit From the Thyroid Full Profile Test?
The Thyroid Full Profile may be useful for people who require broader thyroid assessment than TSH alone can provide.
People with symptoms potentially associated with thyroid dysfunction - Hormones and antibodies are assessed within one profile.
People with a previous abnormal TSH result - Free T3, Free T4 and additional markers can provide more context.
People with a known thyroid condition - Repeat testing may be useful when clinically appropriate.
People with a family history of autoimmune thyroid disease - Thyroid antibodies are included.
People taking thyroid medication - Blood testing may form part of treatment monitoring.
People with unexplained changes in energy, weight or temperature tolerance - Thyroid function may be one area worth assessing.
People who want thyroid antibody testing alongside hormone measurements - Anti-Tg and Anti-TPO are both included.
How to Prepare
Do not stop prescribed thyroid medication without medical advice.
Where repeat monitoring is being performed, using similar collection conditions can make trends easier to interpret.
Symptoms and Reasons to Consider the Thyroid Full Profile Test
Thyroid conditions can produce varied symptoms, and similar symptoms can also occur for many other reasons.
Persistent tiredness - Both underactive and overactive thyroid conditions can affect energy.
Unexplained weight changes - Changes in thyroid hormone activity can influence metabolism.
Feeling unusually cold or hot - Thyroid hormones contribute to temperature regulation.
Changes in heart rate or palpitations - Thyroid dysfunction can influence cardiovascular activity.
Changes in bowel habit - Thyroid hormone abnormalities can affect gastrointestinal motility.
Hair thinning or dry skin - These may occur with thyroid dysfunction but are not specific to it.
Menstrual or fertility concerns - Thyroid function can be relevant to reproductive health.
Previous thyroid antibody positivity - Repeat testing may sometimes be appropriate.
Severe palpitations, chest pain, fainting, marked confusion or other acute symptoms require prompt medical assessment.
Thyroid blood results should always be considered alongside symptoms, medication and medical history.

Your completed Thyroid Full Profile is returned securely.
When Will I Receive My Results?
Results are generally expected within approximately 2 days.
Turnaround begins once the specimen enters laboratory processing.
Occasional repeat or confirmatory analysis can extend reporting.
Understanding Your Results
TSH, Free T4 and Free T3 should be interpreted together because each provides different information about thyroid regulation and circulating hormone levels.
Total T4 adds further information about circulating Thyroxine.
Thyroglobulin and Thyroid Peroxidase antibodies can indicate autoimmune thyroid activity but do not independently determine how well the thyroid is currently functioning.
It is possible to have thyroid antibodies while hormone concentrations remain within reference ranges.
Abnormal results may require clinical review, repeat testing or additional thyroid investigations.
