Hello everyone, just joined the community this evening. I am 28 years old- tomorrow actually- and had a TT February of 09 and RAI in June. I recently had a thyroglobulin level of 4.9 and last week it was 6.6. I had a negative result today from my total body scan but had two injections of thyrogin this week to take another thyroglobulin test today... I'm wondering if another RAI treatment would be the best option for my situation, especially if my thyroglobulin levels come back even higher than 6.6. Thank so much in advance. PS- I don't think it's related, but I have had Type 1 diabetes since I was 8. KP
