Approximately 4.5 to 12.5
Nothing. Thyroid levels are reported in terms of TSH, free T4 and total T4 level values.
4-11 ug/dl at 10 years and older.
Free T4 is free (unbound) thyroxine.
I have a lowTSH,0.06 and within the normal range readings of T3,T4 I am being treated for Hypothyroidism, have weight gain problems, dry skin etc. Should my current dose of 150 be increased to 200?
Hey my name is Julee and doctors have been telling my i have hyperthyroidism as well as graves disease for years now. My level was the exact same ... 0.26 TSH and 8.4 for T4 Total. I feel weak and have alot of anxiety. My heart races alot and i am also tiered all the time.
A doctor orders a free T4 blood test (or FT4) to see if your thyroid gland is working properly. The "free" part refers to released thyroxine in your system. The free T4 part actually means it is only measuring the unbound T4 (which is usable) the free T4 blood test is better than just the T4, you need to know how much free T4 (unbound and usable) hormone there is in your body to help determine whether you are suffering from thyroid disease.
Thyroid function - Hypothyroidism. A low level of thyroxine and high level of TSH indicate an underactive thyroid.
The old Total T4 test (TT4) is no longer considered the best way to test for T4 levels. T4 and T3 can both be bound by other proteins and hormones in the body. When this happens, the T4 or T3 is not usable by the body. The body can only use T4 and T3 that is not bound, or free. For this reason, Free T4, which only tests the free levels of the hormone, is now preferred over Total T4 testing as more accurate.
If my thyroid T4 free blood results are dropping what does this mean?
Your doctor will determine if you need to be on Armour Thyroid which is used to raise the level of T4 hormone. Speak to your physician.
No.
