T4, also called thyroxine; the T4 test is a medical test used to measure the levels of thyroid hormones in the blood. This T4 lab test is often conducted to diagnose thyroid disorders and monitor treatment effectiveness for thyroid conditions.
The T4 blood test, also known as the thyroxine blood test, is a common blood test used to evaluate thyroid gland function. The thyroid gland is responsible for producing hormones that regulate metabolism, growth and development, and energy levels in the body. During a T4 blood test, a healthcare provider will take a small sample of blood from the patient's arm and send it to a laboratory for analysis. The laboratory will measure the level of thyroxine (T4) hormone in the blood. There are two types of T4 hormone: Free T4 (FT4) and total T4 (TT4). Free T4 is the portion of T4 that is not bound to proteins in the blood and is considered the biologically active form. T4 total blood test includes both free T4 and T4 that are bound to proteins.
Abnormal T4 levels can indicate an underlying thyroid condition, such as hyperthyroidism (an overactive thyroid) or hypothyroidism (an underactive thyroid). Symptoms of these conditions can include weight gain or weight loss, fatigue, hair loss, and changes in heart rate.
It is important to note that the T4 blood test is just one of several tests that can be used to evaluate thyroid function, and results should be interpreted by a healthcare professional in conjunction with other clinical information. Max Lab ensures that free T4 blood tests are conducted under the supervision of medical professionals. Highly-qualified doctors ensure that the results of the free T4 test are accurate.

A T4 blood test may be prescribed by a healthcare provider if they suspect a patient has a thyroid condition or to monitor the effectiveness of thyroid hormone replacement therapy. Some common reasons a T4 blood test may be prescribed to check the normal T4 levels or high T4 levels include:
The time required for T4 test reports can vary depending on the laboratory and healthcare provider. Generally, results for T4 blood tests can be available within a day or two of the blood draw. However, some laboratories may take longer to process the sample, and healthcare providers may also need additional time to review and interpret the results.
After the T4 test results are available, the healthcare provider will typically review them and determine the next steps based on the patient's individual health situation. If the T4 levels are within a normal range, no further action may be necessary. However, if the T4 levels are abnormal, the healthcare provider may order additional tests, such as a TSH blood test or thyroid ultrasound, to help diagnose the underlying cause of the abnormality.
