Of course! Free Thyroxine (FT4) test, often called “thyroxine bioavailability analysis,” gauges blood levels of free T4. Thyroxine, also known as T4, is the main hormone that the thyroid gland produces and is essential for controlling energy balance, metabolism, and total metabolic rate. The term “free” component describes thyroxine that is not attached to blood proteins, making it active and accessible. This type of thyroxine is a better measure of thyroid function than total T4 levels.The description of the thyroxine bioavailability analysis highlights the significance of “health heart diagnostics” (HHD) in the management of cardiovascular health. Heart rate, cardiac contractility, and the general functioning of the cardiovascular system are all influenced by thyroid. It also has an impact on metabolism and cholesterol levels, two important aspects of cardiovascular health.
