Reading Labs: The Importance of T4 in the Bigger Picture

In this episode of Reading Labs, Nurse Doza discusses the importance of understanding the T4 thyroid panel. T4 is a potent thyroid hormone, but it’s not the ideal hormone we want - that’s T3. Nurse Doza explains that when taking thyroid medication like Synthroid, it’s crucial to check your free and total T4 levels to see if the medication is converting and absorbing properly. However, she emphasizes the need to also consider TSH and T3 levels to get the bigger picture of your thyroid health.
