help me understand test results

[shanny2]

Originally, I had tingling and buzzing in my hands and feet.  I had blood tests:  results low TSH (.26) and low Free T4 (.74) which I guess is unusual,  I had a head MRI to rule out a tumor on my pituitary glad and it was normal.
  I had more specialized blood work which showed receptor antibodies positive which may suggest I guess some kind of acute inflammatory process?  I have an appointment in 2 weeks to see an endocrinologist.  All of this waiting....I had to wait so long for all of my results and I am wondering if you can give me any information about what could be going on.  I would appreciate anything you can tell me while I wait.

"I wondered why they didn't test for the T3" - they seldom do at first unless you ask. Many doctors are not well educated in thyroid and rarely extend education past their outdated medical schooling. And medical school itself is outdated in many illnesses.

T4 is converted to T3 if your thyroid and liver do its job right, not all do. T4 is a storage hormone for making T3 as you need it. So T3 is what you feel.

I have already done a lot of research on those two diseases.  The weird part is that one shows Hypothyroidism and the other shows possibly Graves.  I got the MRI because they thought there was a tumor on the pituitary gland.  I freaked out about that too!  
I just get impatient with all of the waiting 'cause I didn't even feel sick.  I only asked the doctor about the buzzing/tingling and asked him if I could have it checked.  That's when all the other stuff came into play.  I didn't want to delay treatment as my sister passed away because she waited to find out about something (not thyroid).  Thanks for your response.  I wondered why they didn't test for the T3.  Thanks for responding.

Thanks for responding.....I had the b12 tested when I had the thyroid blood tests the 1st time and it was okay.

Have you had your vitamin b12 levels tested?  Low levels can cause tingling in hands and feet.

Depending on your positive antibody test, it would be Hoshi (hypo) or Graves (hyper) - google these or look on our health pages (upper right). Sometimes symptoms dont come to the surface years after finding antibodies.

Cant really go by TSH only. if we did, yours looks great. You need free T3 testing. This is part of the big picture that is missing.

Good you had the MRI, not easy to get.

Waiting is what we all do, sorry about that. The more info you get, the more possible info we can explain. So the more you get, feel free to post here.
