Free thyroxine index is calculated by dividing the total T4 by the TBI value T-uptake ratio. The mean free thyroxine level was significantly higher in patients with primary hypothyroidism than in euthyroid control subjects 136 - 0201 ngdL versus 110 - 0155 ngdL respectively.

The free thyroxine index has generally been replaced by Free Thyroxine in the assessment of thyroid function but is occasionally useful when a free T4 result is suspected of being anomalous.
Results should always be interpreted using the range from the laboratory that performed the test. Measurement of serum free thyroxine index may provide additional case detection compared to free thyroxine in the diagnosis of central hypothyroidism. In adults normal total T4 levels are within 50 to 120μgdL micrograms per deciliter.
59-132 mcgdL or 20 years. FTI increases could be caused by hyperthyroidism whilst decreased FTI could be attributed to hypothyroidism. FTI Thyroxine T4 Thyroid Binding Capacity.

The finding of an elevated TSH and low FT4 or FTI indicates primary hypothyroidism due to disease in the thyroid gland. Calculation CALC Immunoassay IA LOINC Codes Performing Laboratory. 08-2 ngdL 10-26 pmolL In adults.
To interpret test results use the reference range in the laboratory report. If your Free Thyroxine level is more than the normal range it may result in Hyperthyroidism whereas a lower level of Free Thyroxine Level can result in Hypothyroidism. 10 to 20 uIUml.
It is an attempt to obtain an indirect measurement of free thyroxine. P. Interassay precision CV is.
In most cases free thyroxine also known as free T4 is good indicator of thyroid function along with TSH and other measures. A normal free T4 range in adults is 8 to about 18 nanograms per deciliter ngdL. TT4-82-185 101-206 and 9-194 μgdL.
Approximately 85 of thyroid hormone released by the thyroid gland is T4 with approximately 15 being T3. Free T 4 can be measured by equilibrium dialysis gold standard of free T 4 assays or by immunometric techniques influenced by serum levels of lipids proteins and certain drugs. Reference range for T-uptake ratio is 0712 and for FTI is 61100 μ gdL.
Serum TSH had no significant correlation with TT4. Free thyroxine fT 4 or free T4 is generally elevated in hyperthyroidism and decreased in hypothyroidism. Ad If You Have Hashimotos You May Be At Risk for Developing Thyroid Eye Disease TED.
Normal thyroid levels specifically for TSH thyroid stimulating hormone fall within the range of 05 to 50 mIUL milli-international units per liter. Free thyroxine index FTI normal range 53142 The FTI is obtained from the measurement of serum T 4 and FBC. Serum free T 4 directly measures unbound thyroxine.
The free thyroxine index FTI is determined by the following calculation. Normal Ranges for Free T4. 4 55 11 123 μgdL 60.
Tests measuring free T4 either a free T4 FT4 or free T4 index FTI more accurately reflect how the thyroid gland is functioning when checked with a TSH. The normal level of Free Thyroxine in the body of an adult is 08 to 28 nanograms per deciliter ngdL. 54-115 mcgdL 57-148 nmolL Reference ranges for free thyroxine FT4 are as follows.
Reference ranges depend on the method of analysis. Service Area must be determined.
