Results in 24 hours.


What is this test?

A thyroid blood test is often used to assess the functioning of the thyroid gland. The thyroid gland in the neck produces hormones that regulate various bodily functions, including metabolism, energy levels, and growth. The blood test measures the levels of specific hormones produced by the thyroid.

Thyroid blood tests are commonly performed to diagnose thyroid disorders, including hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). The blood test results help doctors determine the appropriate treatment plan, monitor the effectiveness of ongoing treatment, or detect any changes in thyroid function.

Thyroid Function

Free Thyroxine (FT4) and Thyroid Stimulating Hormone (TSH) are important health markers for evaluating thyroid function. Their measurements offer insights into the thyroid gland's function and help diagnose conditions like hyperthyroidism or hypothyroidism.

Understanding Thyroid Function

If you are experiencing symptoms associated with thyroid disorders, such as unexplained weight changes, fatigue, changes in mood or energy levels, hair loss, menstrual irregularities, or other related symptoms, a thyroid blood test can help determine if thyroid dysfunction is the underlying cause.

Routine Check-up

Thyroid blood tests may be a part of routine check-ups, especially for individuals at higher risk of thyroid disorders, such as women over the age of 60, individuals with a family history of thyroid disease, or those with certain autoimmune conditions.

Monitoring Thyroid Medication

For individuals already diagnosed with a thyroid disorder and receiving thyroid hormone replacement therapy, regular thyroid blood tests are essential to monitor the effectiveness of the medication and ensure hormone levels are within the target range.

Fertility and Pregnancy

Thyroid dysfunction can affect fertility and pregnancy outcomes. If you are planning to conceive or are pregnant, your healthcare provider may recommend thyroid blood tests to assess thyroid function and ensure optimal hormone levels for a healthy pregnancy.

Unexplained Weight Changes

Significant and unexplained weight loss or weight gain can be an indicator of thyroid dysfunction. A thyroid blood test can help identify any underlying thyroid-related issues contributing to these changes.

Heart-related Symptoms

Thyroid hormones play a crucial role in regulating heart function. If you are experiencing symptoms such as a rapid or irregular heartbeat, palpitations, or unexplained changes in blood pressure, a thyroid blood test may be ordered to assess thyroid function and rule out any thyroid-related cardiac issues.

Goitre or Thyroid Nodules

If your doctor detects an enlargement of the thyroid gland (goitre) during a physical examination or if thyroid nodules are discovered, a thyroid blood test may be conducted to evaluate thyroid function and rule out any underlying abnormalities.
