The Total Thyroxine (T4) Test is a blood test that measures the levels of T4 hormone in the blood. T4 is a type of thyroid hormone that is responsible for regulating metabolism, growth and development, and other important bodily functions.

During the Total Thyroxine (T4) Test, a healthcare professional will draw blood from a vein in your arm and send the sample to a laboratory for analysis. You may be asked to fast for 8-12 hours before the test to ensure accurate results.

Normal T4 levels vary depending on age, sex, and other factors, but in general, levels between 5 and 12 μg/dL are considered normal. Low levels of T4 may indicate hypothyroidism, while high levels may indicate hyperthyroidism or other conditions.

If your Total Thyroxine (T4) Test results indicate abnormal levels, your healthcare provider may recommend further testing or treatment, such as thyroid hormone replacement therapy or medications to regulate thyroid function.
