What are antithyroglobulin antibodies, mine are within normal range now but I have no idea what it is or what happens when it is high or low. Sorry this might be a stupid question but I wasn't given any info when the doc office alled with results.
Thanks, Annette
Thyroglobulin antibodies and thyroid peroxidase antibodies are the thyroid autoantibodies that docs check to see if they are elevated and if so it indicates Hashimoto's thyroidititus.
dea is right. What the thyroglobulin and thryoid peroxidase antibodies are, are particles made by your immune system which are directed at destroying the above. Sounds kinda stupid eh? Why would your body be making antibodies against itself? Well, that's what medicine has been primarily trying to fix for the 60-70 years. Just like rheumatoid arthritis, lupus, diabetes etc. etc. hashi's is a disease where your immune system thinks the very body that it's trying to protect is the enemy. Pretty nasty if you ask me.
Does Hashi's occur w/ only 1 type of antibody present, or does tpo have to be elevated? To rule out Hashi's my doc only ordered TPO-anti testing, which came back neg.

To DEFINITIVELY diagnose Hashimoto's requires a biopsy of thyroid tissue. TPO and/or Thyroglobulin antibodies are often indicative of possible or likely Hashimoto's, but cannot definitively diagnose it.

MEEP, this is very interesting, why then would one have antibodies if it is not Hashi's? What would cause there to be thyroid antibodies? Does anyone with thyroid problems have antibodies? or is there another underlying condition that can cause one to have thyroid antibodies? I know antibodies indicates Hashi's, just wondering if it can mean something else.

Hi! I had the fine needle biopsy (for a nodule) results came back that 1 of the 3 smears looked suspicious. The lab suggested that you need to rule out Hashi's, if it is not hashi's another biopsy needs to be done. I had antibodies test TPO was elevated. So Meep is correct.

I have been confused by this too for the longest time.
What are antithyroglobulin antibodies?
