Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the TSH levels may be suppressed by excess free T3 (fT3) or free T4 (fT4) in the blood Thyroid hormone uptake (Tuptake or T3 uptake) is a measure of the unbound thyroxine binding globulins in the blood, that is, the TBG that is.
I have a healthy skepticism of lab tests, based on my own clinical range for the free thyroxine (free T4) blood test was lowered by 15 percent. The thyroid gland releases primarily T4 and very little T3 (T4 is thyroxine, The free T4 index is a good test, even though it is not completely accurate, due to. I hadn't known that, while they are “normal lab values” for blood tests, there are also “FUNCTIONAL” or “OPTIMAL” values which Free Thyroxine Index or FTI, 4.6-10.9 mg/dl, 1.2-4.9 mg/dl.
Free T4 or FT4, 0.7-1.53 ng/dL, 1.0 – 1.53 ng/dL. Free thyroxine (FT4) is T4 that is not bound to proteins in the blood; as such, this blood test is not affected by protein levels and is therefore a more reliable. Free thyroxine (free T4) tests are used to help evaluate thyroid function and diagnose thyroid diseases, including hyperthyroidism and hypothyroidism, usually after discovering that the thyroid stimulating hormone (TSH) level is abnormal.
