Brief Answer:
Get free t3 and t4

Detailed Answer:
Hello

Thanks for the query

If TSH is normal and t3 and t4 levels are normal then I recommend you to get free t3 , free t4 and anti TPO for confirmation.
Other issues that closely mimics hypothyroidism are deficiency of Vit b12 and vit d. Please get these levels as well.

I hope I was of help, if you have any further queries please get back to me

t3 and t4 were also okay. are the blood levels of these always accurate?
free t3 and free t4 were okay. What is TPO?

Answered by Dr. Rakesh Madhyastha (21 hours later)

Brief Answer:
Anti thyroid antibodies

Detailed Answer:
Hello

Thanks for getting back. Anti tpo is anti thyroid antibodies, these antibodies attack one's thyroid cells. However in these patients free t 3 and t4 would be sub normal. In your case I recommend you to get other tests done which I have suggested in my previous reply to you.
