Symptoms That May Indicate You Need a Thyroid Function Test

Thyroid disorders often develop gradually, making them easy to overlook. Common symptoms include:

Persistent fatigue
Weight changes
Feeling unusually cold or hot
Hair thinning or hair loss
Dry skin
Anxiety or depression
Difficulty concentrating

Mood changes
Constipation or frequent bowel movements
Increased heart rate or palpitations
Swelling at the front of the neck
Irregular or heavy periods
Reduced fertility

If these symptoms continue or worsen, a thyroid blood test can help identify the underlying cause.

What Does Our Private Thyroid Function Test Include?

Our comprehensive thyroid blood test measures several important markers to provide a complete picture of your thyroid health.

Thyroid Stimulating Hormone (TSH)

TSH is the main hormone used to assess how well your thyroid is working. The pituitary gland produces it and controls the production of thyroid hormones.

We include TSH in every thyroid function test. Abnormal levels can help identify an underactive or overactive thyroid, allowing for early diagnosis and treatment.

Free T4 (Thyroxine)

Free T4 measures the amount of active thyroxine in your blood. This hormone plays an important role in regulating your metabolism, energy levels, and overall health.

At The Luna Clinic, we test Free T4 alongside TSH to provide a more accurate assessment of your thyroid function and hormone balance.

Free T3 (Triiodothyronine)

Free T3 is the active thyroid hormone used by your body’s tissues. It helps regulate metabolism, heart rate, and energy production.

At The Luna Clinic, Free T3 testing helps us investigate suspected thyroid disorders and gain a more complete understanding of your thyroid health.

Thyroid Peroxidase (TPO) Antibodies

TPO antibodies help detect autoimmune thyroid conditions, including Hashimoto’s thyroiditis. High levels may indicate that your immune system is affecting your thyroid gland.

At The Luna Clinic, TPO antibody testing supports early diagnosis and helps guide the most appropriate care for your thyroid health.

Thyroglobulin (TgAb) Antibodies

Thyroglobulin (TgAb) antibodies provide additional information about autoimmune thyroid disorders. They are often tested alongside other thyroid markers.

At The Luna Clinic, TgAb testing helps support diagnosis and ongoing monitoring of thyroid conditions for more personalised care.

Thyroid Receptor (TRAb) Antibodies

TRAb antibodies are commonly linked to Graves’ disease, a condition that causes an overactive thyroid. Testing these antibodies helps confirm the diagnosis.

At The Luna Clinic, we use TRAb testing to support accurate diagnosis and monitor your condition when needed.

Comprehensive Thyroid Health Assessment

A complete thyroid assessment looks beyond a single blood test. We evaluate your hormone levels, antibody results, symptoms, and medical history together.

At The Luna Clinic, this comprehensive approach helps us understand your thyroid health and provide personalised advice based on your individual needs.

Thyroid Conditions We Help Identify and Monitor

Our thyroid testing can assist in diagnosing and monitoring a wide range of thyroid disorders.

Hypothyroidism

Hypothyroidism, or an underactive thyroid, occurs when your thyroid does not produce enough hormones.

Our comprehensive thyroid testing helps diagnose hypothyroidism early, allowing timely treatment and ongoing monitoring where needed.

Hyperthyroidism

Hyperthyroidism occurs when your thyroid produces too much hormone, causing your metabolism to speed up.

Our thyroid function tests help identify hyperthyroidism quickly, supporting accurate diagnosis and appropriate treatment.

Hashimoto's Thyroiditis

Hashimoto’s thyroiditis is the most common autoimmune cause of an underactive thyroid. It develops when the immune system attacks the thyroid gland.

Using hormone and antibody testing, we can help diagnose Hashimoto’s disease early and support effective long-term management.

Graves' Disease

Graves’ disease is an autoimmune condition that commonly causes an overactive thyroid. Early diagnosis helps reduce symptoms and prevent complications.

Our comprehensive thyroid assessment includes antibody testing to accurately diagnose and monitor Graves’ disease.

Goitre

A goitre is an enlargement of the thyroid gland that may cause swelling or discomfort in the neck. It can occur with normal, low, or high thyroid hormone levels.

Thyroid blood tests help identify the underlying cause and determine whether further investigations are required.

Thyroid Nodules

Thyroid nodules are small lumps that develop within the thyroid gland. While most are harmless, some may require additional assessment.

Blood testing is often the first step in evaluating thyroid function and deciding if further investigations are needed.

Autoimmune Thyroid Disease

Autoimmune thyroid disease occurs when the immune system attacks the thyroid gland, affecting its normal function over time.

Our thyroid antibody tests help detect these conditions early, allowing for more personalised care and monitoring.

Subclinical Thyroid Disorders

Subclinical thyroid disorders occur when thyroid blood test results are abnormal before noticeable symptoms appear.

Comprehensive testing helps identify these early changes, making it easier to monitor your thyroid health and begin treatment when appropriate.

Private Thyroid Testing for Fertility and Reproductive Health

Healthy thyroid function plays an important role in fertility for both women and men.

Even mild thyroid hormone imbalance can affect ovulation, menstrual cycles, sperm quality, embryo implantation, and pregnancy outcomes.

At The Luna Clinic, thyroid testing is often recommended as part of a comprehensive infertility assessment.

Identifying thyroid abnormalities early can improve reproductive health and support successful fertility treatment.

Thyroid Function and Women's Hormonal Health

Thyroid hormones work closely with other reproductive hormones throughout a woman’s life.

Poor thyroid function may contribute to:

Irregular menstrual cycles
Heavy or light periods
Difficulty conceiving
Recurrent miscarriage

Polycystic ovary syndrome (PCOS)
Pregnancy complications
Perimenopausal symptoms
Menopausal hormone imbalance

Understanding your thyroid health can help identify factors affecting your hormonal wellbeing and guide appropriate treatment.
