No Thyroid

I'm a little confused about my TSH/FT4 results.  My thyroid was removed in 2007, I have been on Synthroid 200 mcg since then.  Jan, 2009 results - TSH = 1.63/no FT4; Jan. 2010 - TSH = 29.25/FT4 = 1.35; Feb. 2010 - TSH = .32/FT4 = 1.52. What would cause these fluctuations?

The TSH is a responder to thyroid function and many things play apart in our thyroid wellness that sometimes changes things up and down.

I'd like to see the Free T3 and Free T4 blood patterns here more and ask you how you feel comparing the 2 TSH labs?

Take it on an empty stomache every day at the same time. No food one hour before or after. Call your doctor for more info
