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

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. ...Read more

Hyperparathyroidism: Sounds as if you have hyperparathyroidism. You didn't mention your renal function, though, as chronic kidney disease (CKD) is a very common cause of hyperparathyroidism. You should have your renal function and serum phosphorus levels checked...then get back to us! This condition, hyperparathyroidism, depending on the cause, is very treatable but can cause some serious problems if not. Good luck! ...Read more

Thyroiditis: Why are you having your thyroid tested? what are your symptoms? start from the begining. Medicine is not about scans and numbers. TSH is suppressed by the elevated T3 (liothyronine) as feedback inhibition. I would expect normal to high uptake but it can be low in some cases of Hashimoto's thyroiditis. thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thyroid may be burning out. ...Read more

My thyroid uptake was high. I feel terrible. Should i consider ablation of the thyroid? My TSH is low normal and my T3 (liothyronine) andt4 are high normal. Help!

Yes/drugs/surgery.: You apparently have a serious issue with your thyroid. Although your lab values are not evident, the fact that you feel bad is enough to see your doctor for urgent treatment. One option is ablation of a nodule, not your whole thyroid, by radioiodine. Another is surgery. If you have high hormone levels, drugs like ptu (propylthiouracil) & DEXA and potass-iodode are needed. Again see your doctor asap for work-up. ...Read more

Subclinical Hypothyr: Your TSH is quite high with normal t4, it suggest you have subclinical hypothyroidism, it may be due to hashimoto disease and need to check for antithyroid antibodies and need to ba treated with replacement thyroid hormone till TSH comes down to within normal range consult your doctor or an endocrinologist. ...Read more

How soon after a thyroid scan should you wait before an uptake scan?

How soon after a thyroid scan should you wait before an uptake scan?

One after the other: The exact scanning time after taking the capsule varies according to the isotope and protocol used. For i-123 and low i-131 the uptake and the scan is usually done at 24 hours. A thyroid probe directed to your neck measures the radioiodine uptake, this is follow by a gamma camera scan which makes an image of your thyroid gland based on the radioiodine distribution. ...Read more
