Thyroid Blood Test Question?
I have been taking 50mcg (5mg) of a thyroid supplement for 12 years. It has worked perfectly. A new doctor in a new location with a new and different lab now tells me that the TSH is " 8.90H. "
He wants me to take MORE sythroid daily.
I'm confused. If my thyroid is not producing enough stuff, why does the test say H? (for 'high?')
Why would I take MORE if it is High?
(I'm also suspicious, as I have NO symptoms of problems, and my daughter has a misread for thyroid at the same place. She was placed on meds, and because of her horrific side effects, she was re- tested and found out she didn't need it at all.)
Suggestions?

A high TSH indicates an underactive thyroid. TSH is your body's way of trying to stimulate more thyroid hormone production (T4). It has detected low T4 levels in your bloodstream and is trying to stimulate more production.
Yes a higher dose of thyroid medication makes sense. You should have been having annual blood tests to catch the fact that your thyroid has been getting worse.
I wouldn't wait for symptoms to arise before taking the increased dosage but if you are concerned, have another blood test to confirm the results.
