i am in confusion,help me
hi everyone, i am new to this website. I am 28yr old, i am trying to concieve, last month i came to know my TSH is 18, T3 and T4 were normal, antibodies were >600.so my doctor gave me 75mcg thyroxin, again i tested my level after 1 month,2 days before, it is 0.21,this time my doctor has reduced my dosage from 75mcg to 50mcg. i dont understand how does thyroxin again help me in boosting up my level back from 0.21 to 2. i am little confused.
As i have less knowledge about this, can anybody tell me, how does it work?
I just want to become normal and start to try for pregnancy. its been 3 yrs for my marriage.if i knew all these before i could have made my health normal by this time.from 6 months we are trying for pregnancy. please pray for me.
Thank you in advance.

thanks goolarra...
actually my doctor told me once my TSH come to normal value then i should check for FT3 and FT4 and TPO antibodies.
And yes my doctor told me not to try for pregnancy atleast for 2 months, so i am just waiting for everything to be normal.
And Thanks a lot, your answers really helped me to understand how my thyroid is varying and how my medicines are working. i am really very thankful to you.

In the labs you posted above, there's an inconsistency between your FT3 and FT4 levels. FT4, at 12.1, is right on the floor or the range, indicating hypo. However, FT3, at 6.06) is high in the range. It's 80% of range. Your high FT3 is probably what's keeping you from having symptoms.
You should insist that your doctor test FT3 and FT4 EVERY time you have labs. TSH is a screening test at best and should never be used alone to treat. If your doctor won't test those, you should find a more savvy thyroid doctor.
A change in TSH from 21 to 18 really isn't significant. TSH is very volatile and can change as much as 70% just depending on the time of day the blood is drawn. Both labs are probably correct. TSH is always changing.
Has your doctor mentioned anything about Hashi's?
If I were you, I'd want my thyroid condition stable before conceiving. Your baby will be dependent on your hormones until his thyroid develops. Low maternal thyroid levels can cause miscarriage or developmental problems. By "stable", I mean that you should be on a consistent dose for several months with periodic lab work. Also, I'd want to make sure I had a doctor who ordered the correct tests and who I was confident could manage my meds. Pregnancy will change your need for meds, so FT3, FT4 and TSH have to be monitored carefully. Just my opinion...

And i have no symptoms at all.... i went for general enquiry and overall checkup as we decided to become parents. So i was asked to do following tests.
TSH, Prolactin, Heamoglobin, Fasting Blood sugar tests.
except TSH , all other tests were normal. so i came to know i am hypothyroid. Then i was asked to do FT3 ,FT4, TPO antibodies, TSH tests again in some other laboratory. Otherwise i have no symptoms, my menstruation cycle is regular, i am very healthy.
But one thing i dont understand, in one laboratory my TSH was 21 and after 3 days i went to different laboratory and it showed 18. so i decided to continue to test in one lab always.But its confusing, so much difference in values. :( . i dont know which lab is correct.

thanks goolarra... now i know how my medicines are working on me.
last month FT3 and FT4 with biological reference range are...
parameters Observed Values Biological Reference range
FT3 6.06 pmol/L 3.1 - 6.8 pmol/L
FT4 12.10 pmol/L 12 - 22 pmol/L
After taking medicine for 1 month,i was told only TSH test, so i dont know how it had affected my FT3 and FT4. Now 50 mcg thyroxin i am taking and november 15 i got to do TSH test again.
Hope by next month my levels are normal.so that i can try for baby.
Thanks once again goolarra.

What are the refeence ranges for your FT3 and FT4? Ranges vary lab to lab, so you have to post ranges with results. Also, does your lab report say that these tests are free T3 (or FT3) and free T4 (or FT4) or does it just say T3 and T4. If "free" is not specified, then the tests were for total T3 and total T4.
Elevated TPOab indicates that you have Hashimoto's thyroiditis, which is an autoimmune disease and the most prevalent cause of hypo in the developed world. Your will progressively lose more and more thyroid function as the antibodies destroy your thyroi'd ability to produce hormone.
TSH is counterintuitive; when TSH is high, you are hypothyroid (low thyroid function), and when it's low, your are hyperthyroid (high thyroid function). When everything is working properly, the higher your FT3 and FT4 levels, the lower your TSH. (I have to caution here that TSH is a very poor indicator of thyroid status and should never be used alone to manage thyroid meds. FT3 and FT4 levels are much more important.)
So, when you started taking meds, your FT3 and FT4 levels most likely increased, which made your TSH go down from 18 to 0.21. Your doctor feels that 0.21 is too low, so he has decreased your meds from 75 to 50 mcg. The decrease will cause your FT3 and FT4 to go back down a little, and your TSH will go back up a little.
How do you feel? Are you having any hyper symptoms? Have your hypo symptoms gone away?

hi goolarra...
you are correct. my doctor wants my TSH to be in range 2 to 2.5.
my FreeT3 is 6.06 pmol/L and my FreeT4 is 12.10 pmol/L. My doctor said FreeT3 and FreeT4 are in proper range.
But TPO antibodies are more than 600. so i have been given 75mcg thyroxin for 1 month. after 1 month only TSH is been tested. so it was 0.21 now. so to bring my TSH to 2 to 2.5, i have been now given 50mcg thyroxin.
My question is, by taking 75mcg thyroxin my TSH has gone down from 18 to 0.21, again 50mcg thyroxin tablet will bring TSH 0.21 to 2? how?

I'm not sure I understand what you're asking. You had a TSH test a month ago with a result of 18. After one month, your TSH was tested again, and it was 0.21, correct?
"i dont understand how does thyroxin again help me in boosting up my level back from 0.21 to 2." Please explain where the "2" comes into play. Is that the level your doctor is trying to achieve?
Is your doctor testing FREE T3 and FREE T4 as well as TSH? If so, please post results and reference ranges. Ranges vary lab to lab, so they have to come from your own lab report.
