A test measuring total thyroxine (T4) levels in the blood. T4 is the main hormone produced by the thyroid gland, and abnormal levels can indicate thyroid disease.
Total Thyroxine (T4) Test Test in Guwahati Overview
The Total T4 (thyroxine) test measures the amount of thyroid hormone T4 in the blood. T4 is produced by the thyroid gland and plays a crucial role in regulating metabolism, energy, and overall growth.
Why consider this test?
This test helps assess thyroid function. Low T4 levels can indicate hypothyroidism (underactive thyroid), while high levels can suggest hyperthyroidism (overactive thyroid). These conditions can affect metabolism, energy levels, and overall health.
Who should get this test done?
Individuals who have symptoms of thyroid dysfunction, such as weight changes, fatigue, sensitivity to temperature, or mood changes, should consider getting this test. It is also important for those with a family history of thyroid disease or individuals undergoing treatment for thyroid conditions.
More Information
The Total T4 test measures both bound and free T4 hormone levels in the blood. T4 levels are often assessed along with other thyroid function tests, such as TSH (thyroid-stimulating hormone), to get a more comprehensive view of thyroid health.
