I was having some sort of allergy, so my doctor checked my THS, T3, and T4. All of which were normal. She also checked my ATG and Anti TPO.
(I'm not in the UK, just in case the reference ranges are different than the ones is the UK, I'll mention the normal ranges)
TSH was 3.6 (normal is between 0.43 - 4.10)
ATG was 25 (normal is under 100)
Anti-thyroperoxydase antibodies were high 105 (normal is under 34)!
She said this means in the future I might get hypothyroidism in the future. Or it might be a wrong reading, since ATG seems normal.
That really scared me!
2 months later, I redid the test in another lab (private one since state labs in my country are not that reliable) and results of ATG and Anti TPO both came out very high!
ATG was 135 (normal is under 4.11)
Anti TPO was 89 (normal is under 5.6)
My TSH in this test is 1.24 (normal is between 0.35 - 4.9)
I know, I need to see an endocrinologist. But that will take time till I get an appointment, and I need to put my mind at ease.
1- So, is this really a harbinger that I will have hypothyroidism? And is it a matter of months or years or what? Is this reversible? Can I do something my lifestyle to stop this from happening?
2- How come 2 months ago my anti TG was normal, and now it is super high?!
3- Is it normal for my TSH to move from 3.6 to 1.24 in two months? Both numbers are within the normal range thanks God, bit Is this usual with TSH to change over time, or it should be stable for each person?
4- I have a cat. Could this be messing my lab results? Because I've read this online:
"Some patients who have been exposed to animal antigens, either in the environment or as part of treatment or imaging procedures, may have circulating antianimal antibodies present. These antibodies may interfere with the assay reagents to produce unreliable results."
Wishful thinking, I know it might be so.
Sorry for blabbing, but I'm really worried.
Thank you all.
