    What is a Thyroid Function Test?

    The thyroid gland is a small, butterfly-shaped endocrine organ found in the lower front part of the neck. It plays a vital role in regulating various metabolic processes in the body by producing and secreting hormones, primarily thyroxine (T4) and triiodothyronine (T3). Thyroid function tests (TFT) are a series of blood tests that evaluate thyroid health by measuring the levels of thyroid hormones. The most common components of TFTs include measurements of thyroid-stimulating hormone (TSH), total thyroxine, and total triiodothyronine.

    The purpose of thyroid function testing is to evaluate how well the thyroid gland functions and to diagnose potential thyroid disorders. Abnormal results on the TFTs can help identify conditions such as hypothyroidism, which is characterised by insufficient hormone production, or hyperthyroidism, where excessive thyroid hormone levels lead to disturbances in metabolism. TFTs are also crucial for monitoring treatment effectiveness in individuals with known thyroid disorders and guiding necessary adjustments to therapy.

    Thyroid Function Test Results & Interpretation

    The results of Thyroid Function Test are interpreted using the normal range for each hormone in the thyroid panel. The thyroid function test interpretation is as follows:

    ParameterBiological Reference RangeInterpretation
    TSH0.400 to 4.049 µIU/mLNormal TSH levels indicate proper thyroid function. Increased TSH may suggest hypothyroidism, while low levels are associated with hyperthyroidism. In pregnant women, TSH levels vary by trimester.
    T4Total T4: 5.53-11.0 μg/dLNormal T4 levels reflect healthy thyroid function. Low levels are indicative of hypothyroidism, while elevated levels suggest hyperthyroidism or excessive thyroid hormone intake.
    T3Total T3: 0.97-1.69 ng/mLNormal Total T3 levels suggest adequate thyroid hormone production. Low levels may indicate hypothyroidism, while high levels are associated with hyperthyroidism.

    In pregnancy, the TSH levels can vary significantly. They are stated as below:

    TrimesterTSH (µIU/mL)
    First0.100 to 2.50
    Second0.200 to 3.00
    Third0.300 to 3.00

    The T3 and T4 levels change in every stage of pregnancy. They are as stated below:

    TrimesterT4 (μg/dL)T3 (ng/mL)
    First7.57 - 8.131.21 to 1.32
    Second7.17 - 8.641.13 to 1.64
    Third7.07 - 8.441.16 to 1.51

    FAQs on Thyroid Profile Test

    No, fasting is not typically required for Thyroid Test.

    Common symptoms that indicate a thyroid disease include weight changes, fatigue, hair loss, and changes in mood or energy levels.

    The frequency of TFTs depends on your health condition, especially if you have an existing thyroid disorder. For routine monitoring, annual testing is generally recommended, but your doctor may advise more frequent testing depending on your symptoms.

    While some thyroid disorders, such as hypothyroidism, can be managed effectively with medication, permanent reversal of thyroid damage may not always be possible. However, early detection and treatment can help control symptoms and prevent further complications.

    TFTs are simple blood tests with minimal risks. You might experience mild discomfort, slight bruising, or swelling at the puncture site, but serious complications are extremely rare.

    Abnormal TFT levels may be caused by a variety of factors, including thyroid dysfunction (hypothyroidism or hyperthyroidism), certain medications, iodine imbalance, and hormonal changes. Other conditions, such as autoimmune disorders, can also affect thyroid levels.

    Improving your thyroid levels typically involves following a balanced diet rich in nutrients like iodine, selenium, and zinc, managing stress, and taking prescribed thyroid medications regularly. Avoiding excessive iodine and regular monitoring also helps maintain optimal thyroid function.

    Yes, thyroid function is commonly monitored during pregnancy since thyroid hormone levels can fluctuate significantly. Proper monitoring ensures that both maternal and foetal thyroid health are managed, helping to avoid complications.

    Orange Health Labs ensures that you receive your TFT report timely. TFT results are generally available within 6 hours of collecting the sample.

    Abnormal TFT results can indicate conditions such as hypothyroidism (low thyroid function) or hyperthyroidism (excessive thyroid activity).

    What Do Thyroid Function Test Measure?

    Thyroid Function Test measure the concentration of specific hormones circulating in your bloodstream that commonly include:

    Thyroid Stimulating Hormone (TSH) : TSH is a key hormone produced by the pituitary gland in the body. It regulates the production of thyroid hormones. Elevated TSH levels often indicate hypothyroidism, while low levels can suggest hyperthyroidism.

    Triiodothyronine (T3) : This parameter measures the amount of T3, which plays a critical role in regulating metabolism. Abnormal T3 levels may indicate issues with thyroid hormone production and metabolism.

    Thyroxine (T4) : This test measures the primary hormone secreted by the thyroid. It provides essential insights into thyroid health, with low levels typically indicating an underactive thyroid and high levels indicating an overactive thyroid.

    Thyroid Function Test Normal Range

    The Thyroid Function test normal range may vary for pregnant and non-pregnant individuals, reflecting the physiological changes that occur during pregnancy. In non-pregnant individuals, established reference ranges indicate optimal thyroid hormone levels necessary for maintaining metabolic health. However, during pregnancy, thyroid hormone levels undergo significant fluctuations. As a result, the normal range for TSH, T3, and T4 are adjusted based on the trimester of pregnancy.

    Conversely, any deviations from the thyroid function test normal values can indicate potential thyroid dysfunction, such as hypothyroidism or hyperthyroidism. The results of the test should be discussed with a doctor for accurate interpretation and diagnosis.

    Factors Affecting Your Thyroid Test Results?

    Several factors can influence the results of thyroid function tests, leading to fluctuations in the levels of thyroid hormones.

    • Medical Conditions That Can Impact TFT Results

    Conditions such as hypothyroidism or hyperthyroidism can lead to an increase or decrease in TSH levels. The levels of T3 and T4 hormones reduce in hypothyroidism, whereas their levels rise in hyperthyroidism. Disorders like Graves' disease or toxic nodular goitre can also alter thyroid hormone production. Additionally, serious illnesses including heart attack, kidney failure, liver illness, trauma etc., can also affect the results of TFTs.

    • Impact of Food/ Other Factors on TFT Results

    The presence of too much iodine in the body affects TFT results. This may happen with tests such as a CT scan with contrast. In rare cases, consuming foods that contain iodine may also cause abnormal TFT results in individuals with an existing thyroid disease. Fasting and malnutrition can also affect the concentration of thyroid hormones. Thyroid hormone levels may decline in the presence of a severe acute illness.

    • How Medications Affect TFT Results

    Medications can significantly impact TFT results by altering thyroid hormone levels. Vitamins and mineral supplements containing iodine or biotin affect TFT results. Drugs such as phenothiazines, phenytoin, and glucocorticoids may suppress TSH release, leading to false low readings. The excessive intake of thyroid hormone medications or supplements, painkillers, and chemotherapy can also suppress TSH levels and elevate T3/T4 levels.

    When to Seek Medical Advice Based on TFT Results

    Abnormal thyroid function test (TFT) results can indicate underlying thyroid disorders that require medical attention.

    • Consulting a Doctor for High/Abnormal TFT Levels

    If your TFT results are outside the normal range, it’s crucial to seek medical advice as they may suggest hypothyroidism, hyperthyroidism, or other thyroid-related issues. A doctor can further evaluate you to identify the exact condition and recommend appropriate treatment.

    • Addressing Abnormal TFT Results

    Abnormal TFT results may necessitate lifestyle modifications and/or treatment. Your treating doctor might recommend dietary changes, weight management, increased physical activity, or stress management techniques to support thyroid health.

    • When Lifestyle Changes Aren’t Enough

    In some cases, lifestyle changes may not adequately address thyroid imbalances. If you continue to experience symptoms or if your TFT results remain abnormal despite these adjustments, it is essential to consult a doctor for further evaluation. They may suggest medications including thyroid hormone replacement therapy for managing thyroid levels.

    • Medication Adjustments Based on TFT Levels

    If you are already undergoing treatment for thyroid dysfunction, TFT levels will be considered to adjust medications. High or low hormone levels may require a change in dosage or a different medication altogether. Regular monitoring of TFT results is essential to ensure that treatment remains effective and that your thyroid function is appropriately managed.

    Key Benefits of Thyroid Profile Test

    TFTs offer a range of benefits, from early detection of thyroid disorders to ongoing monitoring of existing conditions.

    • Preventing Complications Related to Thyroid Health : By regularly assessing thyroid hormone levels through TFTs, potential complications associated with thyroid dysfunction can be prevented. This can help prevent more severe health issues, such as cardiovascular problems, weight changes, and mood disorders, contributing to better overall health.

    • Cost-Effectiveness of Regular Testing : Regular TFTs are a cost-effective strategy for maintaining thyroid health. The thyroid function test cost is a small investment compared to the potential expenses that may arise from untreated thyroid disorders.

    Common Diseases Diagnosed by Thyroid Profile Test

    TFTs are widely used to diagnose a range of thyroid diseases and related illnesses such as:

    • Hypothyroidism

    • Hyperthyroidism

    • Hashimoto’s disease

    • Graves’ disease

    • Thyroid nodules

    • Thyroid cancer

    Risk Factors for Thyroid Disorders

    Several risk factors may be linked to thyroid disorders. These include:

    • Family history of thyroid disease

    • Gender (females may be at higher risk)

    • Increasing age (older than years)

    • Previous thyroid problems

    • Autoimmune diseases (e.g., type diabetes, pernicious anaemia, and Addison’s disease)

    • Iodine deficiency or excessive iodine intake

    • Getting exposed to radiation, particularly in the neck region

    Complications of Untreated TFT Levels

    Failure to address abnormal TFT levels can lead to serious health complications that can affect various bodily functions. Complications may include:

    • Severe fatigue and weakness

    • Mood disorders like depression

    • Infertility or reproductive issues

    • Goitre (enlargement of the thyroid gland)

    • Osteoporosis

    • Heart problems (heart failure or stroke)

    • Myxoedema coma (due to hypothyroidism)

    Overall, untreated thyroid disorders can significantly impact the quality of life.

    How to Maintain a Healthy Lifestyle

    Maintaining thyroid health is crucial for overall well-being. Here are some key tips to promote a healthy lifestyle:
