Scan Effectiveness Factors ?

[Guest guest]

Hi,

I'm trying to get a little better understanding of the effectiveness of

scans based on TSH levels. My TSH levels are not climbing to 30,

despite being on a M,W,F only synthroid for 3 weeks, and now a 5 week

run of no synthroid at all. The TSH test of the last three weeks were

5.3, 10.2, then 6.8 last wednesday. My nuclear medicine doctor has

proposed doing the small dose and scan this coming wednesday and

friday. I am wondering if any research or thoughts exist regarding the

effectiveness of the scan if someone isn't at a TSH level of 30 or

above ?

And with my TSH levels are climbing very slowly, and even going

backwards, is it just a matter of time before they creep up to the 30

level ? My surgeon is known to be very thorough, but I understand that

the only thing supressing TSH is thyroid tissue. I'm happy to wait if

it will make a better scan and uptake of the ablative dose.

I'd love to hear from people with similar slowly rising TSH levels, and

learn what they did. This is sort of an addendum to my previous post.

Thanks.

Jay
