T3 Uptake
Also known as T3 resin uptake. Measures the number of unbound sites on the thyroid binding proteins. Levels are used to identify thyroid states (hypo and hyper) as well as selenium and iodine sufficiency. Can also be used to identify how much binding globulins are available to bind to thyroid hormones.
