Blood Drug Testing

Thyroid blood tests - what do they mean?

Have been hyperthyroid (Grave's) for two years. Been on various different dosages of carbimazole - ranging from 5 - 40mg per day. Have also had a few breaks from Carbimazole. I am presently on 20mg daily. My blood teats are confusing me and no one has told me what they mean this time - I see my GP in two weeks - he's good at explainig them - but can't wait until then. March 1st 2008 Free T4 = 5 Free T3 = 1.2 TSH = not detected Previous January 28 2008 Free T4 =14 Free T3 = 2.3 TSH not detected. Am I still hyperthyroid? Am I under control? OR am I hypothyroid. Any help would be greatly appreciated - I have muscle cramps, fatigue and have put 14lb of weight on in 4 weeks!!! Feeling dreadful. Help Please. Thanks. Ps TSH has always been not detected!!

1. Well, normal T4 is 4.5 to 11, so I guess you're "under control." Can't say the same about your weight and the fatigue. That sounds hypothyroid. Ummm.... He may back off your med a little.
2. I haven't been able to find test values with explanations, but I do know that some go down & that's not good. Is the TSH not detected because test not being taken? Ask MD to take it & also Calculated T4 & Calculated T3. Your symptoms sound hypothyroid. Call MD Mon AM & ask to speak to him because of symptoms & then ask him to explain test values. This way you won't have to wait 2 weeks! Good luck
3. Well your TSH is still none detected, which to me would seem like you still have a hyperthryroid. What kind of medication did they put you on? It might not be your thyroid, it could even be your pituitary. The pituitary is what makes TSH, so if you don't have that at all, I would think that is the problem. Anyways, I wish I could be more of help, I listed some really good links at the bottom, I think they will help you out!
