Low thyroid (TT3) from 24.4 being normal I have a 21.81?

does anyone know how bad could it be having a thyroid problem, my results came out low , what should I do?Low thyroid (TT3) from 24.4 being normal I have a 21.81?
Here's one site that explains what the thyroid does and how it can be hard to determine why lab values are sometimes hard to comprehend (especially in women):http://www.womentowomen.com/hypothyroidi...
Was your TT3 the only lab value out of normal range? I'll go check your other questions now.
I am assuming TT3 is total T3. This is one of the thyroid hormones. Is this the only result that was off ? Do you feel tired or fatigued? This may be a sign that your thyroid is underactive.
If your thyroid is underactive you can take medication which is actually just thyroid hormone. This is done on a daily basis.
You can see an endocrinologist (thyroid and metabolism specialist), if you need to be treated. Only a doctor can diagnose you.
