Thyroid test results

by vtlisa, Jul 26, 2004 12:00AM
I had an appointment with my GP who was very concerned about my blood test results -TSH 0.18 and T4 1.1 - and immediately scheduled me for a MRI explaining the numbers indicated I have a tumor on the pituitary gland.  She also scheduled me an appointment with the Endocrinologist (3 1/2 weeks out due to his vacation).
The following day I received a call from the GP's assistant explaining that the GP had talked to the Endo and it was decided to cancel the MRI until I see him.
My questions are: do the numbers in fact reflect a pituitary problem and if yes is it prudent to delay 3 weeks before beginning the process for treatment?
Thank you very much for your time.

Every lab has it's own set of normal values. I assume the T4 is low  and your TSH is inappropriately low. These numbers alone would not support or exclude a tumor in your pituitary region. They do indicate some degree of pituitary dysfunction, cause unknown. I would need to take your history and examine you to determine if a MRI is indicated. I agree with the endocrine consult. They will most likely repeat the test and add other markers of endocrine and pituitary function. If this is a "pituitary tumor", they are usually benign tumors. Perhaps you should ask the endocrine forum for their advice. Good luck.
