Tests needed

[Guest guest]

Hi ,

Here's a quote from a post Elaine made to Mediboard; I think it answers the

question of which antibody tests to get for autoimmune thyroid disease. If I

leave anything out, hopefully someone else will straighten it out!

" There are three types of TSH receptor antibodies: blocking, stimulating, and

binding TRAb. Stimulating TRAb are the same as TSI. These antibodies all bind to

the TSH receptor. . . . Most people with autoimmune thyroid disease have a

combination of TRAb. The type of TRAb that predominates at the time determines

if you're hyper or hypo, with TSI [stimulating TRAb] predominating in GD. But

over time 20% of people with GD quit producing TSI and start producing blocking

TRAb. "

So I guess the proper tests would be, separately, for stimulating TRAb and

blocking TRAb. (I'm not sure that whether there's a need to test for binding

TRAb.)

Best wishes,
