Blood work for Thyroid

uscgirl211

Hi, I was wondering do you all know if there is a certain time of day that is best to have your thyroid levels checked? Morning? Afternoon? Take my meds before I go have the blood work or wait? Eat or not eat before having them checked?

P.S. I had a total thyroidectomy so, I am reliant upon my cytomel and synthroid...

I've often wondered the same thing. I've just decided to be stay consistent. I take my meds at 6:30am and then usually go have my blood work done at 8:30-9 before I eat breakfast.

Hey, I was wondering if you all could tell me what each of the thyroid test mean?

My T4 Free (Direct) is .95 the range is .82 - 1.77 is it LOWER the # the hyper you are?

My TSH is 1.360 the range is .45 - 4.50 is it the LOWER the # the hyper you are?

My Triiodothyronine, Free Serum is 2.0 the range is 2.0 - 4.4 is the LOWER the # the hyper you are?

HELP! I just dont understand what each level means?
