Description

The T4, Free tests are used to measure a person’s levels of thyroxine (T4) and triiodothyronine (free T3) hormones. These hormones are produced by the thyroid gland and play a key role in regulating the body’s metabolism. Higher levels of T4 and Free T3 can help increase the rate of metabolism, while lower levels can lead to symptoms like fatigue, weight gain, and depression. The T4, Free tests are important for assessing an individual’s health, as they can indicate whether a person has hypothyroidism (low thyroid hormone levels) or hyperthyroidism (high thyroid hormone levels). If these levels are abnormal, further testing may be needed to determine the cause of the abnormality and the best treatment options.
