what does it mean if on my thyroid panel, my t-uptake was elevated?

May be nothing: If the rest of the tests are normal, and the t3ru (t3 (liothyronine) resin uptake) is abnormal, the thyroid is probably working normally. T3ru reflects the amount of thyroid binding proteins in the blood, and can be high in women taking birth control pills, estrogen or who are pregnant. It's main use is to correct total T4 levels for protein changes, but is less useful since most labs check free T4 instead now.
