Understanding TSH 3rd Generation

by education_nut, May 06, 2008 01:06PM
I had a TSH 3rd Generation w/reflex 4ft test done.  The result were Free 4T was 1.1 and TSH was .27.  Should I be concerned?

These are essentially normal labs -- would watch the TSH as it is a bit low.  Would repeat TSH and FT4 in a few months to make sure there is not a trend towards hyperthyroidism.

Not a typo. :) The doctor says I need to do more tests to rule out a pituitary tumor. Should I be concerned? What type of tests will they do and what will determine whether or not it is in fact a tumor that is causing my level to be so high? Is there anything else that would cause this level to be this high? Thanks!!!

My mom 3rd generation TSH is  0.137 UIU/ml  (normal range is 0.47 - 4.64)  what does this mean?  Please advise what to check and do.  She had history of Atrial fibrillation, are these related?  Fatty liver infltration with hepatic cyst, multiple cholelethiasis with dilated common bile duct. She also had carotid artery disease, and history of TIA
