INTRODUCTION
The thyroid gland is responsible for producing hormones that regulate many critical body functions. When this gland isn’t functioning properly, it can lead to a range of health problems. One of the most reliable ways to check the condition of your thyroid is through a blood test, which measures two important hormones: Thyroid Stimulating Hormone (TSH) and Free T4 (FT4).
This particular test is designed to evaluate the functionality of your thyroid. It measures the levels of TSH and FT4 in your blood to determine if your thyroid is either underactive (hypothyroidism) or overactive (hyperthyroidism). Thyroid conditions are relatively common, yet they often go undiagnosed due to the subtlety of symptoms, which are easily mistaken for other conditions.
Both conditions can result in symptoms such as fatigue, changes in mood, and fluctuations in weight.
Additionally, this test can be useful for tracking IgG levels after infections. Immunoglobulin G (IgG) levels tend to decline over time after an infection, and monitoring these levels can help you understand how your body is responding.
HOW DOES THIS TEST WORK?
A blood test is the best way to detect potential health issues, or monitor existing ones.
Whether you are actively managing a condition or simply want to stay informed about your health, blood tests provide a clear and efficient way to get the answers you need.
Our thyroid function test is straightforward and hassle-free. Simply visit one of our pharmacy locations to have your blood sample collected.
The turnaround time is swift – you’ll receive your results the day after your sample reaches our lab. Our laboratory operates around the clock, allowing our in-house team of GPs to evaluate and communicate your results efficiently. The quick delivery of results ensures that you can take action if needed without delay.
However, it’s important to remember that blood tests should not be your sole method of diagnosing health conditions. If you are experiencing symptoms, it is crucial that you consult a healthcare professional for a thorough evaluation.
WHO SHOULD TAKE A THYROID BLOOD TEST AND WHEN?
Anyone experiencing symptoms that could be linked to thyroid imbalances should consider taking a thyroid blood test. Hypothyroidism and hyperthyroidism each present with distinct symptoms, and recognizing these can help determine when a test might be necessary.
Hyperthyroidism (Overactive Thyroid) – Symptoms can include unexplained weight loss or gain, sweating, tremors, sensitivity to heat, and reduced libido. This condition is more frequently seen in individuals over the age of 60, and women are particularly prone to developing it.
Hypothyroidism (Underactive Thyroid) – Symptoms can include persistent fatigue, dry skin, decreased appetite, memory problems, and difficulty concentrating. As with hyperthyroidism, this condition is more common as people age and is also prevalent among pregnant women.
Additionally, people who have certain pre-existing conditions may be more likely to develop thyroid issues and should regularly monitor their thyroid function. These include:
. Type 1 Diabetes
. Addison’s Disease
. Coeliac Disease
. Individuals taking specific medications such as Lithium and Amiodarone.
WHAT DO YOU TEST?
THYROID (2 BIOMARKERS)
Thyroid function is often impaired without noticeable early symptoms, which is why regular testing can be so important.
Thyroid Stimulating Hormone (TSH)
This hormone is produced by the pituitary gland and sends signals the thyroid to produce thyroid hormones. These hormones are critical in regulating metabolism, body temperature, and muscle strength. Abnormal TSH levels can indicate thyroid disease. It is commonly tested alongside Free T3 and Free T4 to provide a fuller understanding of your thyroid function.
Free T4 (Thyroxine)
Free T4 is one of the main hormones produced by the thyroid gland and plays an important role in metabolism and growth. By measuring Free T4, we can help diagnose conditions like hypothyroidism and hyperthyroidism. This hormone also plays a role in diagnosing female fertility issues. Free T4 is often tested with TSH and Free T3.
FREQUENTLY ASKED QUESTIONS
Why is a thyroid test important?
Essential hormones are produced by the thyroid gland and travel throughout the body. Among the most important roles of the thyroid is regulating metabolism, which impacts your brain function, heart rate, and body temperature.
What are the early warning signs of a thyroid problem?
Early symptoms of thyroid dysfunction can be subtle but may include unexplained hair loss, trouble concentrating, dry skin, and puffiness in the hands, face or feet.
What is the normal range for thyroid function, and what happens if my results are abnormal?
The normal range for TSH levels is between 0.3 and 3.05, and the range for Free T4 is 9 to 23. If your results fall outside of these ranges, our medical consultants will flag the abnormal results and provide recommendations on the next steps. This often includes a referral to your doctor for further evaluation and possible treatment.
How should I prepare for the test?
It’s important to notify your doctor if you are taking any medications that might affect thyroid function. Imaging tests with contrast dye containing iodine can also affect results, so mention any recent medical tests. If you’re pregnant, it’s important to inform your healthcare provider, as pregnancy can impact thyroid levels.
